Holy shit,good work - MJ I had good luck on ChatGPT produxing real designs via freecad macros. See the spindle I designed. Try to integrate chat. I think we can getbchat to donreal FEA via frecad macros too.

Been using Gemini 3 in visual studio. It seems to do a better job of understanding spacial ideas and locations when described in text. makes a good pairing for openscad.

going to have it make notes of ai sessions here : https://github.com/OpenSourceEcology/LifeTrac/blob/main/LifeTrac-v25/AI%20NOTES/conversation_log.md

On January 2, 2026, a session fixed visual issues and optimized hydraulic cylinders for the LifeTrac V2.5 loader arm in OpenSCAD by correcting bucket cylinder misalignment using actual arm tip coordinates. Upgraded from a 16-inch to 18-inch stroke through iterative mounting adjustments, aligning the crossbeam with physical arm cutouts while adding diagnostics. Final setup resolved visuals, geometry, and constraints with optimized stroke and positions.

• Trying out Google Gemini 3. seems to do a good job.

• Talking to github AI (Claude Opus 4.5) with VS Code plugin.
  • Created first draft of LifeTrac v25 machine design using purely AI prompts for OpenSCAD.
  • Process is render openscad, look for errors, tell AI about errors, apply changes, re-render and repeat.
  • Claud 4.5 seems to be a bit better than GPT 5.1 Codex Max in understanding physical world of openscad

RotoKnitic v19.01. Knitic Genealogy.

April 29, 2019

• Mar from CircularKnitic suggested using solenoid to operate the needle movement
  • due to the limited travel distance, i think some sort of lever with a bearing will be needed
  • will need to transfer the lever's circular motion into linear

April 27, 2019

• perhaps could define p4clear possibly as low as 1/2 of -p4rampH? maybe -1/3*p4rampH ?
  • this would reduce needle travel and shrink mountain
• Applied to show CircularKnitic at MakerFaireTulsa https://tulsa.makerfaire.com/

April 21, 2019

• working on rotoknitic idea
  • https://github.com/OpenSourceEcology/circular_knitic_pick-a-needle
• need to make rack and pinion
  • https://www.thingiverse.com/thing:2072364/files

April 20, 2019

• documented sock sized circular knitic build

Mar 2, 2019

• Circular knitic build and design changes

Feb 16, 2019

• started a BOM scad file to auto generate bolt size/length/count output
  • formatting is not very user friendly but nice to have calculated output

Feb 15, 2019

• Looking up parts for build
  • User:Dorkmo/Builds/CircularKnitic
• need to get full list of bolts and nuts
  • M3 Socket Screws

Jan 19, 2019

• worked on knitic
  • changed to a printed drive gear
    • avoiding a $6 single source part
  • added holes for stepper motor
    • could use regular DC, but in the future might use steps to customize mountain use
  • changed table top to octogon, added holes for mounting legs
    • calculating tabletop OD using stepper motor width and gear sizes
  • added some needles to the full assembly model to check placement
  • need to add bolts to smallbearingholder to make sure the nut/head dont hit anything

Jan 15, 2019

• Review CEB Press Controller v19.01
• more circular knitic work, tweaking the Z bearing holder to be more printer friendly
• searching for local CNC Laser cutting shops for hire, found 4 or 5

Jan 2, 2019

• proposed new design RotoKnitic v19.01

Jan 1, 2019

• cleaning up circular knitic design
