Time Log


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

STEAM Camp


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
> chmod +x Cura-mb-master-armhf-20191209.AppImage

Then you just need to run the app image file:
> ./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:
> 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.

I'm working on replicating the D3D Simple build we worked on in November, recreating it here alongside Marcin's recent changes.

I have used a belt sander to keep a good sharp bevel

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


Oct 20 - Oct 24

Working on Simple Extruder and Universal Toolhead Mount. Note also that D3D_Simple#Part_Library has more.
