Hi everyone,
I have a small problem, I received my printer this week, no problems during assembly, while the axes walk properly except the extruder motor ...
the Motor work (tested on the X axis)
In manual extrusion does not work ...
I tried several software but no change.
I print at 200 ° c so I do not see where is the problem ...
(Sorry i have a bad english)

Firstly, please check if the extruder motor driver(I think it's A4988) is bad: Swap the extruder motor driver with x motor driver. Then let all the axes auto home, check if x motor can move. If x motor can not move, we can conclude that the extruder motor driver is bad.

Motor is fine, so as the driver.
Can you extrude the filament with your hand?

Do you have a multimeter? There a screw on motor driver, rotate the screw to increase the power of motor, the voltage between screw and GND is around 1V.

I can not make handling now, so if I understand, I connect my multimeter on the screw and on the motor GND pin and I turn until 1V?

This is one of the potential reasons, if the extruder motor can run without filament.

The motor does not work with or without filament, he turned once during handling firmware but nothing after.
