Hello,

installing new Mark2 is finished. It seems all  is working properly. Unfortunately printing the calibration-gcode (xy_calibration.V03.gcode), Extruder 1 works fine, Extruder 2 does not deliver filament, because its feeder does not rotate. Moving filament with extruder 2 on the display, filament is delivered as expected. Using a 24V - 400W power supply does not help. What can be the reason ?

If i remember right, you have to choose a material for the second extruder first (on the printer: Material Settings -> Extruder 2).

Without a known material there is no known temperature and the "cold extrusion prevention" kicks in.
