AMS2 Pro… Why does it have to retract the filament all the way back after each print?
If I print the majority of the time with slot 1, then why not just have it cut and extract out of the extruder/hot end to clear it?
Doing this would save a lot of wear and tear on a number of parts:
bowden tubes
ams motors and all related parts.
If you change colors/filaments, THEN it would go through all the motions of full retraction and load / swapping of the filaments. Otherwise, it just has to move the filament about 2" back into the extruder for your next print.
