Hi, can anyone explain why stepper motor in extruder seems to take only one step?
(I heated it above cold extrusion limit)
After that it rotates freely.
There is same problem in two printers but 3rd printer works fine with same marlin setup.
stepper driver is ok, wiring is ok, motor is ok...
I also tested E1 slot (instead E0) with same result.
setup: MKS GEN L 2.1 // marlin 1.1.9.1 // A4988 (16 microstep)
