'''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.


*pushed some tweaks to github on torch table idea
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


*Found the Gates Brand GT2 belt website
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.
