Back to OSE Linux setup on different machine!

Fri Jan 31, 2020

From Boston! Confirmed one location option for March 2020 Open Source Microfactory STEAM Camp: NADAA architecture office ground floor shop/ Harry Lowd@ [[1]]

Unpack and reassemble D3d

She needs more attention but has a name

Downloaded NOOBS fraction of time and uncorrupted

Team call 9AM CST: Call terminated connection failed via Microsoft edge surprise surprise. Appears call in working on iPhone but y'all can hear me I can't hear you. Did see the chat message. Scrumy overview SORRY you heard that! Rpi Tablet case... listened Day 7 am Utube recording

Road map review:YES!

Imagining this rasppi config with molded hand holds

Unable to add a box to scrummy stating concept case build with found object box dim. 5.5x22cm. Repeated 'refresh' error

Will be good to build in freecad and print so walls have some thickness to provide relief for wire 'bumps' and access. Dimensions can shrink and pi could flip so fan at back. Four holes on back of screen appear to be same dimension as mounting holes on Rpi though different sizes??? Current concept build has plenty of room for adding parts

Thurs Jan 30, 2020

Download software for Raspberrypi and SD memory card formatter

As a beginner I'll use NOOBS (new out of box software) also because I like the name ;)

Review Pulse Width Modulation (PWM) tutorial and recording of Tom's presentation

[[3]]

Board etching: Prep plate by using fine steel wool or gentle abrasive like comet to remove all oil etc. DO NOT TOUCH SURFACE, can leave fingerprints on etch. Transfer the PWM Modular Control for light dimmer (welder in development) sketch Tom developed to plate. Traced sketch and punctured with ball point to use as template for permanent black marker. Made dots through template then connected them. (Note multiple passes and streaky marks does not work)

(Note this sketch has the AC DC transfer bridge on the wrong side + needs updates)

First solution way too strong and permanent marker too dry: 2 parts Hydrocloric acid HCl31% (purchased as muriatic acid): 1 part Hydrogen Peroxide H2O23%

Second round new black permanent marker, correct solution 1 HCl : 2 H2O2 (note solid black will act as heat sink for IGBT)

remove marker with gentle abrasive

Tues Jan 28, 2020

From starting documentation, review ATMEGA328 to Arduino uno (led to pin 13)

Add switch

Be sure Rx to Tx, receive to transmit. This is not yet wired properly RX to TX and missing BREAK AT BACK OF CHIP!!!

This board blinks and shows the reset hack but may or may not be essential

todays excercises 1 File:Plotterpen.fcstd

Print plotter pen and clamp from existing .stl, download and open in cura [[4]]

[[5]]

[[6]]

In CURA review basic and advanced settings see... Check advanced settings for 1.2 nozzle, update profile if necessary

Steps per mm at 100

Layer check/ missing/ change thickness to 1.0 top, check'expert config' settinga no check on spiral contour bottom and top if already set to 1 in Basic and missing

Filament size using 2.85

Check machine settings bed size (does not update with profile update)

save /export Gcode to SD card

note: .stl is the geometry of object, the Gcode depends on the above settings for the printer to read and print

2 Using Inkscape to Generate Gcode

from Image Started with .png, save as .svg, at top bar path/ trace bitmap under multiple scans: creates a group, select colors, smooth, and stack scans was set to 8, could likely reduce to 2, select ok then move one off.

There will be multiple additional copies to delete

export gcode

this is the link to check the Gcode before plotting as above

[[7]]

And here are the files including the un-plotted Gcode file for the OSE sticker (no added lines to 90 for alignment)

File:OESd4dStickpath4.zip

January 26

Wires connected recorded movie... need easy edit app. Free Cad draw tweezers and print Adjust alignment on extruder and to Z axis

From /OSE Microfactory download D3D Universal 8.ini Update profile for CURA for: nozzle size 1.2 retraction

[[8]]

Great prints: add links

refine free cad skills!!

January 25

Build the Printer!

Time Log request: [[9]]
