Thank you again for your hints. Today I meassured the temperature of the stepper motors during a print. They operate at approximately 70C. So i decided to change nothing at the setting of the stepper driver. I only changed the driver of the motor wich gets the hottest with another wich is much cooler. Seems that there is no effect from the driver. The motors still have the same temperature difference as they had before. Culd it be that the motors have different resostance or something?

First of all thank you for your fast reply. Maybe I should order some stepper drivers in advance Seems that these aren't very expensive. @ gr5: thank you for the hint. I found this very interesting http://reprap.org/wiki/Pololu_stepper_driver_board I will check tomorrow. @ dim3nsioneer: I have already read your problems with the drivers. Hope your machine runs well now with new stepper drivers.

Hi, I would like to adjust my stepper driver although it is not recommended according to several posts in this forum. One of my stepper is gteeing slightly hotter than the others. I already know the following page from the wiki about adusting the stepper driver. http://wiki.ultimaker.com/Electronics_build_guide On this Page i can find a warning that it is not recommended to change anything on the stepper driver if you do not have a multimeter and that the stepper driver should be set to 1,15 A. Well, i do have a multimeter but it is not explained how to meassure this current. I can see some meassurepoints at the driver board. But i do not know ho to meassure exaktly. Is there anywhere a good explanation how to adjust the stepper driver or can anyone tell me how this has do be done right?
