I have already tried that, the motor and driver works fine if moved to another output, and another motor or driver put on the extruder output have the same problem! I have also tried to measure the pins on the driver, and to me it looks fine: Without signal GND 0V VDD 5V 1B 12V 1A 12V 2A 12V 2B 12V GND 0V VMOT 12V DIR 0V STEP 0V SLEEP 5V RESET 5V MS3 5V MS2 5V MS1 5V ENABLE 5V Oby mipe - General
