*looking at options for high torque steppers
'''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.
**found this one [https://catalog.orientalmotor.com/item/2-phase-bipolar-stepper-motors/42mm-pkp-series-2-phase-bipolar-stepper-motors/pkp246d15a2 oriental motor]
**needs 24V 1.5A
**I dont think polulu outputs enough to run two steppers on the same driver for the same axis like prusa
**AutoDriver says can handle 3A but not sure how to integrate with arduino control etc

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.


*did some work on [[User:Dorkmo/Ideas/TorchTable|Torch Table]] pet project [https://github.com/dorkmo/OSE-TorchTable-dorkmo-201808 github]
going to have it make notes of ai sessions here : https://github.com/OpenSourceEcology/LifeTrac/blob/main/LifeTrac-v25/AI%20NOTES/conversation_log.md
*changed my openscad render color to Sunset, and text color to Tomorrow Night

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 to swap out hydraulic motor in microtrac freecad file. [[File:430260W3131AAAAA.FCStd]]
=oct 16, 2025=
**i was able to import the file and haphazardly move it to the general area where it belongs.
*Clean up v25 lifetrac bom
**in sketchup i would typically draw some guidelines to find the center of the cricle, then snap the center of the motor to the guide lines in the Z, then the Y. Then grab the face of the motor and snap it to the face of the mount.
*: https://github.com/OpenSourceEcology/LifeTrac/pull/42
*need to learn how to move objects efficiently in freecad
*Need to ask about what style this lifetrac structure design will be
**is there a way to place the face of one object against the face of another?
**is there a way to align the centers of two parts' shapes?
*going to do a test cube [[Developer Test]]
*can you teach an old dog new tricks?

**I'm not sure if thats related to the intel or nvidia.

Jan 2, 2026

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.
