Thank you.
I tested:
- "Marlin 1.1.0-RCBugFix" - Does not work G28 for SCARA.
- "MK4duo 3D" - at G28 only works Z. Does not work X and Y for home.
Maybe I'm wrong with the parameters.
I'm looking for a firmware that was tested on DUE for SCARA.
I mention that the printer works well with firmware "https://github.com/vitaminrad/Marlin-for-Scara-Arm".
Locks up if you increase SCARA_SEGMENTS_PER_SECOND or add LCD.
