Firmware Change Log
- Needs to go back to the same endstops_inverting on X and Y as D3D v 20.04 - which is the first D3D that went back to the 3 wire endstops.
- Latest firmware at D3D Universal appears to be v20.04. This already appears to have been updated to 3 wire endstops, thus using v20.04 firmware should work on D3D v20.07.
- D3D Universal v20.07 here is the first code change on Universal since v20.04.
- D3D Universal v20.04 firmware should work as is. Try it.
