Completed the first model of the most difficult part to CAD in the extruder - the X-Axis bracket. Will now print CAD files and measure their accuracy before making changes to the CAD parameters. Hopefully this process will result in more accurate parts.
Friday March 1 - Saturday March 2
Further work on open sourcing Chinese Prusa i3 3D printer extruder.
Monday February 18 - Thursday February 28
Began the process of open-sourcing our 3D printer extruder: Simple 3D Printer Extruder (see photos and CAD files in the 3D Printer Folder) Started a new unit in Computer Engineering Technology class. Two groups of students are working on OSE materials:
- The OSE Collaborative Contest
- The OSE Filament Extruder
Saturday February 9-Sunday February 17
Hosted a group of six STEM students from School of the Nations in Georgetown, Guyana. STEM Camp at London International Academy. Introduced the concept of the OSE collaborative contest. Introductory FreeCAD activities. Introduced Python computer programming. Printed out various parts for an open source brushless motor. Link to CAD Files (see School of the Nations sub-folder) Article in Guyana Chronicle
Wednesday February 6

Monday February 4
Uploaded version 0.1 of the OSE Collaborative Contest Rules to OSE Collaborative Contest
Wednesday January 30 - Sunday February 3
FRC Build season. Team 6162 Cap Alpaca FreeCAD files
Tuesday January 29
Sunday January 27 - Monday January 28
Discussed record keeping, file sharing and other skills for collaborative literacy. Created a sample page stub: Brushless Motor Design. Asked students to reflect on sessions learning FreeCAD. Found that it is not necessary to learn a whole lot about FreeCAD in order to get students learning it. Demonstrated two sample FreeCAD 0.17 design processes:
- Design a part like a motor adapter: body - sketch a circle - pad - sketch on a surface - pocket
- Design a sketch with constraints - some straight lines and some arcs closed in a loop with particular dimensions and angles.
After that, students were directed to Youtube videos that covered specific additional skills:
- Threading - inner and outer
- Polar patterns
Through this process, I learned how to do these skills from some students and was able to show other students the same, especially with polar patterns.
Sunday January, 20 - Saturday January 26, 2019
Prepared for and welcomed 19 students from Jinling High School in China. Introduced the concept of the OSE Collaborative Contest. Marcin spoke with the group over Jitsi on Thursday and on Saturday and proposed that the students participate in the OSE Collaborative Contest. It was well received despite the students' fatigue from travel and skiing. Introduced FreeCAD and had students download and install it. Some computers do not immediately work with FreeCAD; hope that the problem may be solved. We plan to further discuss the students' participation in the contest tomorrow and 3D print some of their early FreeCAD work on Monday. Created a link to LIA students' FreeCAD work. Currently the folder is being used for FRC preparation. After the FRC robot is built, we are planning to transition to OSE-related work in this folder: LIA OSE Club CAD Files
Thursday January 10 - Saturday Jan 19, 2019
Heaviest schedule of the year - January and February; progress slower during this time. Working on STEM Curriculum for FeF STEM Camps - Summer School 2019.
Wed Jan 9, 2019
- Use a presentation - template - make a copy - pass this to Heydar - document the simple 3D printing extruder for a low cost 3d printer - 
- Homework: Complete STEM Curriculum
January 2, 2019
Ordered parts for a brushless motor to be constructed as part of the contest and part of the Computer Engineering Technology class at London International Academy. In order to make the collaborative contest work, we will need to create a kit of parts to be easily shipped to participating schools.
December 24 2018-January 1, 2019
Took a break. Reflected on plans for OSE London / OSE Club at London International Academy / OSE Collaborative Contest
December 23, 2018
Defined particulars of OSE STEM Camps.
Conversation with Marcin. Research on OSE Club Activities. Planning for winter semester courses' links to OSE - Computer Engineering Technology and Computer Science. Plans to do the following in Computer Engineering Technology: build a brushless motor and ESC from scratch. Computer Science: Programming projects related to OSE - simulation program? Western University Introduction to STEM Class - offer the OSE Competition as a choice for a final project - help administer / judge / communicate / etc.
December 12-21, 2018
Exams and marking - excellent ways to hinder educational progress. Discussed Canadian bill of materials with Russ Purvis. Discussed the upcoming OSE workshop in Prince George, BC currently in the planning phase. Several phone conversations with Charlie. Worked on some particulars for the upcoming OSE competition in January. Contacted a teacher in Iran to invite her to join the competition with her students. Sent a letter of reference to Russ with respect to hosting an OSE workshop.
December 8-11, 2018
Spoke with Charlie about development of OSE workshops. Spoke with Marcin and Catarina about the same. Updated Marcin about development of OSE club at London International Academy. We now have plans to include at least four schools in our first design challenge - School of the Nations in Guyana, Fujing Foreign Language School in Shenzhen and Jinling School in Nanjing. Was approached by a friend to contact Makerspace managers in St. Thomas and Toronto. Arranged a meeting with the makerspace managers at Western University. OSE Marlin v18.10 works for printing with new printer. Successfully printed base layer of a file. It seems that the extruder may have jammed. Will check again as soon as possible. LIA students continue to develop their FreeCAD skills and are able to design parts in parallel according to a spacial plan and assemble them into a larger model. Installed OSE Linux on laptop now with a new old-school 1TcB hard drive. OSE Linux did not recognise the card reader; everything else seems to work very well. Note: Stepper motors on y axis of D3D became alarmingly hot after about 15 minutes of printing. Perhaps this is a configuration issue; may need to resolve this before allowing the printer to do a full print.
December 7, 2018
Using OSE Ubuntu on laptop with fried SSD. Internet has connection through ping but does not display pages in Chromium. D3D Marlin recent version from OSE website installed in printer. Autohome produces a collision of the z axis with the extruder as by default the z probe is off the plate. Tried to move the y axis using various commands such as G0 Y40 and G1 Y40 all of which cause the Y axis to move until it hits the maximum physically possible position. Spoke with Johann Wong about the possibility of combining an OSE Makerspace skills (Arduino, CAD, etc.) + 3D printer workshop with Human Innovation PIE's soft skills innovation workshop through the London International Academy Foundation. Was using wrong Marlin file for D3D printer - will try correct one asap. Suggestions for D3D: use zip ties and clothespin springs for tensioning belts. This has worked exceptionally well and reliably for our Chinese Prusa derivative; the belts have needed nearly no attention in three years.
December 6, 2018
Was about to test print on OSE D3D when SSD crashed. Did Ubuntu fry it? Researching this.
December 5, 2018
