This happens too often.
I post something then come up with the solution.
I have a smoothie 5X. There are 5 drivers. I have
- X-Axis (1 Stepper)
- Y-axis (2 Steppers)
- Z-axis (2 Steppers)
- Extruder (1 Stepper)
Z-axis is pretty straightforward wired in series
I can use the 5th driver to power the other y-axis and simply reverse it in firmware.
