Hello, I recently purchased a Mk3 3D Chameleon to use with my P1P. It was working great although I want to have a single bowden tube go through the case into the print head. A little browsing the forums saw I could set the retraction distance to any arbitrary amount with a firmware update to 3.1. Got an Arduino Uno shortly after that and figured out how to load it.
Now after loading it and setting up the chameleon for a test when the switch is pressed all i get is the motors vibrating no more pulses or movement of the mechanism.
This is the last command / and printout when programming:
