The update of the firmware seems to have solved the issue.

Thanks for your help

1. Motors are only running at 1A and my board has a small fan for cooling.

2. i got a 24V 40A power supply with a mains powered bed, so that shouldn't be the issue either.

It does not extrude at all at the moment. With motors off i can freely rotate my extruder and push filament through. If i tell it to extrude it locks the motor in place and I'm not able to turn it anymore.

I tried it with two different files with the same result.
No it's a D-Bot CoreXY with bowden extruder. Connections are all good.

No error messages. All heaters worked normally.

Hello,

Yesterday i wanted to print something, and everithing worked great for the first 12mm of my model. It looked like it stopped extruding after that. When I searched for the problem, I noticed that my extruder motor did not turn when I wanted to extrude filament. To test if the motor was faulty I changed it to drive E1 and everything worked great again. I started to print another model, but the same thing happened at around 11mm. Why do the drives die mid print? I can't see anything burned or blown on the board.
