The driver module for E0 seems to be broken. If I put it to X or Y the motors move like crazy.

I opened the chassis and checked the VRef of the Stepper Drivers.
The extruder had 1.38V, which is far too high. I changed it to 1.00V.

Unfortunately this wasnt the solution, the problem still exists.

I really like the printer design, but I think I have to return it. I cannot print.

I did some more investigation.
If I extrude from the filament menu, it works fine in both directions and it sounds normal.
So I can exclude a driver/motor/extrusion/cabling problem I think.

Temperature is shown at 210°, so this is no reason to stop the extruder.

And as even the factory gcode file ...

Hi.
I just got a new A30 Pro, did the bed levelling and tried printing from SD-Card.
It starts the print, draws the skirt, then makes a strange noise and stops extruding.
I attached photos of the menu settings and a video. What can I do to fix that problem?
