Hello,
My axis do work but after they move the motors wont stop working (seems like they are under load all the time and making wierd noises).
Ive made video: [www.youtube.com]
The stepper is getting extremly hot after teh axis moved.
Ive a Arduini 2560 with ramps 1.4 (drivers: DRV 8825)
I think i made a mistake in the marlin settings but i couldnt find anything
Hope you can help me

If the motor is getting very hot the current is probably set too high. Current is controlled by a tiny pot on each stepper driver module. Be extremely careful when turning the pot- they break easily and you can short out other connections on the board and blow the driver chip. Turn the pot anticlockwise to reduce the current.
