I have the mk3 version. I ran a few test prints 2 color box to set up the system. I have the switch on the X axis and the switch works, all colors change as expected . my problem is when it loads its not making it to the Micro Swiss extruder gears. I loaded it 1 inch from y adapter. I manual fed the filament into the micro swiss and the extruder ran super fast extruding a good bit , it caused skipping in stepper. best I can figure it seems like its trying to load and retract as if it was a stock bowden setup. I was wondering if there were anyone else who has micro swiss g-code for tool changes.
or how I can alter it. The print speeds are fine. I am sure the speed issue is because it shouldn't be extruding yet cause my filament path is pretty short.
