Stepper Motor/Driver issue
February 15, 2016 11:53AM
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.
