Hello! I am in the process of processing the DaVinci 1.1 Plus printer and originally it had two servo motors for the filament feed. The first is the extruder, the second one served as a puller from the reel in the back of the printer. Question is: how to set up the marlin so that both servos work in parallel? Plate: ramps 1.4, Marlin firmware Fastened E0-extruder E1-extractor Thank you in advance!
