Hello,
I have a Multec Multirap M420 2 Move DUO PRO. I would like to update the firmware, but don't know how to control a switching extruder with a stepper motor. (https://www.makertech3d.com/products/dual-switching-extruder-non-proforge) This hotend is like the hotend of the M420, but the M420 has a stepper motor instead of a servo. So I don't know how to configure Marlin...
