* Eco filament experiments: recycled PP & PET from Robries (Surabaya) -> wallet. It will extrude on D3D but bed adhesion issues; heat bed and chamber will be needed, although with perf plate I believe thin wall geometries will be OK.

* Seed for [[Useful_3D_Prints#D3D_Universal_Calibration_Prints]]
* prepping for Arduino curric - hello world code (potentiometer -> flashing light & tone generator)
* Printing Jeremy's work in progress for pitab on 1.2mm nozzle

= Jan 25 - Feb 2 2020 --- STEAM camp 1 =

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

= Nov 1 - Nov 7 =

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

Also got trip details planned and tickets purchased for Nov 8 - 23

==Camera Module==

<gallery perrow=6>

</gallery>

=Add-On Modules=
#Cordless welder battery pack that also serves as a long-life battery add-on

=Data Collection=
*4.2V after charging 5-set of batteries
*One battery was loose - the connector wire was not over the hole but offset to the side

=Build=
*Parts start - [https://www.facebook.com/groups/398759490316633/permalink/1273208866205020/]

=Software=

== Android options ==
Industrial Android on rPi: https://emteria.com/
Not sure it might be NC, or maybe that's just the service layer they are selling on top of what seems to be mostly a business use case

Also trying other Android Options:
*LineageOS (formerly Cyanogenmod): https://konstakang.com/devices/rpi3/LineageOS15.1/
*Android for RPi: https://www.makeuseof.com/tag/install-android-raspberry-pi/

== Keyboard options ==
Note: Best touchscreen keyboard application on the Raspbian so far is Florence
<br>
> sudo apt-get install florence

<br>
Also trying several other linux on screen keyboard options while building android images to try:
* GOK (GNOME Onscreen Keyboard)
* kvkbd
* onboard
* Florence

== Raspbian installation ==
Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

SD card must be FAT formatted, at least 8GB and preferably 16GB:
https://www.raspberrypi.org/documentation/installation/noobs.md

It's handy to have a usb keyboard and mouse to navigate the install process once the prepared SD card is on the rPi.

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

== Screen ==
What resolution works best for the screen? The directions that came with the screen result in unused pixels on left and right side.

From Product Sheet:
*Native Resolution is 1024 x 600.
*Power Consumption 800mA @ 5v

Product Sheet instructions for /boot/config.txt:
*In terminal "sudo nano /boot/config.txt"
*Comment out "dtoverlay=vc4-fkms-vd3" and "max_framebuffers=2"

==Camera Module==

<gallery perrow=6>

</gallery>

=Add-On Modules=
#Cordless welder battery pack that also serves as a long-life battery add-on

=Data Collection=
*4.2V after charging 5-set of batteries
*One battery was loose - the connector wire was not over the hole but offset to the side

=Build=
*Parts start - [https://www.facebook.com/groups/398759490316633/permalink/1273208866205020/]

=Software=

== Android options ==
Industrial Android on rPi: https://emteria.com/
Not sure it might be NC, or maybe that's just the service layer they are selling on top of what seems to be mostly a business use case

Also trying other Android Options:
*LineageOS (formerly Cyanogenmod): https://konstakang.com/devices/rpi3/LineageOS15.1/
*Android for RPi: https://www.makeuseof.com/tag/install-android-raspberry-pi/

== Keyboard options ==
Note: Best touchscreen keyboard application on the Raspbian so far is Florence
<br>
> sudo apt-get install florence

<br>
Also trying several other linux on screen keyboard options while building android images to try:
* GOK (GNOME Onscreen Keyboard)
* kvkbd
* onboard
* Florence

== Raspbian installation ==
Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

SD card must be FAT formatted, at least 8GB and preferably 16GB:
https://www.raspberrypi.org/documentation/installation/noobs.md

It's handy to have a usb keyboard and mouse to navigate the install process once the prepared SD card is on the rPi.

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

== Screen ==
What resolution works best for the screen? The directions that came with the screen result in unused pixels on left and right side.

From Product Sheet:
*Native Resolution is 1024 x 600.
*Power Consumption 800mA @ 5v

Product Sheet instructions for /boot/config.txt:
*In terminal "sudo nano /boot/config.txt"
*Comment out "dtoverlay=vc4-fkms-vd3" and "max_framebuffers=2"

ChrisCaswell:

Extruder Build
#Unpack heater block from baggie.
#Screw in the 2 heater block screws lightly
#Screw in the thermistor screw lightly, so it still allows thermistor to enter
#Insert heater cartridge with wire on the side of the indent
#Insert thermistor with wire pointing in the same direction as heater
#Screw down the thermistor screw lightly using a 1 mm allen wrench to fasten the thermistor, but very lightly as the screw can go right through the thermistor
#Screw down the 2 larger screws using a 2 mm allen wrench, so that heater is secured. Do this evenly by screwing down one screw then the other and alternating 4 times
#Screw in the 1.2 mm extruder nozzle, until there is 1/2 thread exposed
#Screw the heat break on the other side.
#Heat tighten by connecting the heater to the power supply for 2 minutes. Once hot, place the heater block in a vise, hold the heat break with pliers, and screw down the nozzle with a 7 mm socket or adjustable wrench. Make sure that the nozzle bottoms out against the heat break, not against the heater block- the goal is to close the filament flow gap between nozzle and heat break.
#Once tightened, disconnect power from heater element
#After cooling so you can touch it again, screw on the 6 mm thin nut on the heat break
#Apply thermal paste to the heat break, to cover all threads
#Bend the heater cartridge wire out of the way so you can screw on the heat sink. Hold the bottom of the heater wire with pliers so that you can bend the heater wires down far without breaking them from the heater cartridge.
#Screw on heat sink, so that the heat break sticks out 2 mm above the heat sink.
#Clean off the 3D printed extruder main piece. Add an m6 nut in the middle, then mount the stepper motor. Fit a stepper motor and attach upper right corner using an m3x8 screw and a 2.5 mm allen driver.
#Mount the secondary extruder piece using 3 m3x8 mm screws
#Put heat paste on top of the heat sink and attach the heat sink assembly and fan heat sink to the stepper motor using m3x30 screws and a 2.5 mm allen driver. Do not tighten down fully, as the heat sink location will be adjusted.
#Put the drive gear on the stepper motor shaft, keeping the screw loose
#Insert a piece of 3D printing filament into the heat break, and align the extruder gear with it. Once gear is aligned, tighten down the gear.
#Tighten down the heat sink once the gear is aligned, with the inserted 3d printing filament as the guide
#Insert the 8 mm bearing onto the idler pin of the idler 3D printed piece.
#With gear set, add the idler piece by screwing it down with an m3x18 mm screw, and a 2.5 mm Allen driver.
#Insert the spring into the extruder
#Screw on the fan with the fan blowing into the extruder. Use m2.7 self-tapping screws.
#Screw the blower to the secondary extruder piece using two m3x18 screws
#Insert the height sensor and screw it down using an m6x18 bolt. The bottom of the blue plastic should be 4 mm above the nozzle tip
#Connect the 1 meter long stepper wire to the extruder motor.
#Bundle the wires such that when looking at the front of the extruder, the wires are sent to the right hand side. Use a zip tie to hold the wires together,
#There should be 6 sets of wires, totaling 15 wires: fan, blower, heater, thermistor, height sensor and extruder motor.
#Insert the wires through the split wire loom.
#The black beauty is now ready to run.

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.
.
Also got trip details planned and tickets purchased for Nov 8 - 23

* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

* Eco filament experiments: recycled PP & PET from Robries (Surabaya) -> wallet. It will extrude on D3D but bed adhesion issues; heat bed and chamber will be needed, although with perf plate I believe thin wall geometries will be OK.

* prepping for Arduino curric - hello world code (potentiometer -> flashing light & tone generator)
* Printing Jeremy's work in progress for pitab on 1.2mm nozzle

= Jan 25 - Feb 2 2020 --- STEAM camp 1 =

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

= Jan 25 - Feb 2 2020 --- STEAM camp 1 =

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

= Nov 1 - Nov 7 =

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

= Oct 25 - Oct 31 =
After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.
.
Also got trip details planned and tickets purchased for Nov 8 - 23

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.
.
Also got trip details planned and tickets purchased for Nov 8 - 23

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

= Nov 1 - Nov 7 =

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

Edit: Nov 8 -- updated version of spring tensioner and extruder motor bracket

After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

Also got trip details planned and tickets purchased for Nov 8 - 23

* Eco filament experiments: recycled PP & PET from Robries (Surabaya) -> wallet. It will extrude on D3D but bed adhesion issues; heat bed and chamber will be needed, although with perf plate I believe thin wall geometries will be OK.

= Feb 10 - Feb 16 2020 --- STEAM camp 1 =
* Seed for [[Useful_3D_Prints#D3D_Universal_Calibration_Prints]]
* prepping for Arduino curric - hello world code (potentiometer -> flashing light & tone generator)
* Printing Jeremy's work in progress for pitab on 1.2mm nozzle

= Jan 25 - Feb 2 2020 --- STEAM camp 1 =

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

=Build=
*Parts start - [https://www.facebook.com/groups/398759490316633/permalink/1273208866205020/]

=Software=

== Android options ==
Industrial Android on rPi: https://emteria.com/
Not sure it might be NC, or maybe that's just the service layer they are selling on top of what seems to be mostly a business use case

Also trying other Android Options:
*LineageOS (formerly Cyanogenmod): https://konstakang.com/devices/rpi3/LineageOS15.1/
*Android for RPi: https://www.makeuseof.com/tag/install-android-raspberry-pi/

== Keyboard options ==
Note: Best touchscreen keyboard application on the Raspbian so far is Florence
<br>
> sudo apt-get install florence

<br>
Also trying several other linux on screen keyboard options while building android images to try:
* GOK (GNOME Onscreen Keyboard)
* kvkbd
* onboard
* Florence

== Raspbian installation ==
Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

SD card must be FAT formatted, at least 8GB and preferably 16GB:
https://www.raspberrypi.org/documentation/installation/noobs.md

It's handy to have a usb keyboard and mouse to navigate the install process once the prepared SD card is on the rPi.

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:

Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

== Screen ==
What resolution works best for the screen? The directions that came with the screen result in unused pixels on left and right side.

From Product Sheet:
*Native Resolution is 1024 x 600.
*Power Consumption 800mA @ 5v

Product Sheet instructions for /boot/config.txt:
*In terminal "sudo nano /boot/config.txt"
*Comment out "dtoverlay=vc4-fkms-vd3" and "max_framebuffers=2"

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

=Time Log=
<html><iframe width="600" height="600" src="https://osedev.org/wiki/ccaswell?start=6/1/2019"></iframe></html>

= Feb 24 - Mar 1 =
* PiTab dev
* Eco filament experiments: recycled PP & PET from Robries (Surabaya) -> wallet. It will extrude on D3D but bed adhesion issues; heat bed and chamber will be needed, although with perf plate I believe thin wall geometries will be OK.

= Feb 10 - Feb 16 2020 --- STEAM camp 1 =
* Seed for [[Useful_3D_Prints#D3D_Universal_Calibration_Prints]]
* prepping for Arduino curric - hello world code (potentiometer -> flashing light & tone generator)
* Printing Jeremy's work in progress for pitab on 1.2mm nozzle

= Jan 25 - Feb 2 2020 --- STEAM camp 1 =

== Next time ==
* Better asynchronous communication and coordination, especially for the remote folks, for the collaborative presence to be felt
* Ideally something embedded in the Wiki, so it will stay on the same platform
* Embedded IRC?
* Meeting time to middle of the day
* Curriculum content (lecture section) better to have posted as video link rather than live stream
* Need project manager role, someone to focus on coordinating documentation, managing remote folks, checking in on anyone falling behind
* Printer @1.2mm -> Plotter -> CNC mill toward circuit -> 0.6mm finer prints (printer will get more and more tuned in as the camp goes on)
* Printing from Useful Print library, which will both produce useful goods showing the value, good calibration prints for the machine, and a good development queue for FreeCAD lessons and practice.
* PiTab case needs to get to a steady, stable state; simple no frills enclosure. Ideally it will have nut catches or some other attachment point, so next STEAM camp can iterate on some external modules.

== RPi Software ==

Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/

Used the offline installer package on a FAT formatted 32gb micro SD

== Cura ==

I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/

Downloads:
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

Install procedure:
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable
<br>
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
<br>
> ./Cura-mb-master-armhf-20191209.AppImage

== Camera ==
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3

Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"

Once restarted, you can take a picture like this:<br>
> raspistill -o Desktop/image.jpg

This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.

= Nov 1 - Nov 7 =

Work on Simple Extruder -- Cut/drill/tapped aluminum heat sink block. FreeCADed a jig for alignment (also WIP) - I think the same could be done with heater block.

I bought packs of all the hardware for the universal axis build hoping that I could use the same screws for this - but I am not sure this will be possible.

Spring tensioner needs still most work, the bearing from that is pictured is obviously not going to work...

I have come around to horizontal tool mount; I do feel like it will be more compact and stable. I think could be as simple as 3 holes and wing nuts.. focusing on full functioning of simple extruder first.

Edit: Nov 8 -- updated version of spring tensioner and extruder motor bracket

= Oct 25 - Oct 31 =
After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.
.
Also got trip details planned and tickets purchased for Nov 8 - 23
