Use 2512 SMD resistors in place of strain gauges ( #104 )
...
As suggested in https://github.com/scottbez1/smartknob/issues/24#issuecomment-1073540944 and inspired by https://github.com/IvDm/Z-probe-on-smd-resistors-2512 , this adds 4x 330 ohm 2512 SMD resistors to the back to act as strain gauges, rather than requiring discrete strain gauges to be glued and wired up.
Also applies a few changes I accidentally had pending locally:
- Custom footprints for the 2 3.3v LDO options to clarify the pinout options

- some BOM note updates
Fixes #24
Closes #33

Adding second footprint for 3V3 voltage regulator ( #98 )
...
The voltage regulator that was originally used isn't available at the moment. To provide more options, a second footprint was added to the PCB for an alternative regulator that has a different pinout. Important to note that only one regulator should be used.
Also, adjusted .gitignore for Mac files and KiCad auto-generated backups.

Migrate to KiCad 6 ( #96 )
...
- Updated view_base and view_screen KiCad projects to v6 files
- Updated footprints to v6 versions
- Fixed all DRC errors and most warnings
- Updated CI
- Run on Ubuntu 22.04 runner
- Updated KiBot and KiKit versions
- Use KiBot for 3d rendering now instead of custom scripts
- Switched to using KiCad text variables for replacement rather than raw text find&replace
- Misc design updates
- Exposed bottom-side thermal pad underneath TMC6300 to make it easier to possibly hand-solder
- Separated GND and GNDA nets, replaced connection with a net-tie, and updated corresponding copper fills around HX711
