Temperature of Stepmotor

Hi

One of the stepmotors gets very hot when connected to the computer (i can barely touch it). Also it makes some kind of ticking noise. It's all wired correctly, i've checked this several times. All the motors work, but one is much hotter than the others are. Could the motor be damaged? When I disconnect the usb cable the sound stops.

    The motor is most likely fine. But you might want to check the settings of the motor drivers. See:

    http://wiki.ultimaker.com/Electronics_b ... or_drivers

    The "very hot" and "ticking noise" might indicate that the current is turned up to high.

    (If you disconnect the USB the Arduino is turned off, and that turns off the Polulu step motor drivers)

    i was looking for the adjustment screws on the driver board as it stand in the guide, but i couldn't find any. so i tried to start printing anyways.

    the x-axis seems to work smooth (this stepmotor doesn't get hot), but the y-axis and z-axis aren't smooth at all (these step motors get very hot). they just move a few milimeters, stop for a short moment, and start to move again. also the distance in + and - direction aren't the same so the prints get tilted very badly (about 45°).

    can you help me with that?

    That's almost certain a driver overheating problem. So you need to adjust those tiny pot-meters on the drivers, like in the guide linked in my previous post.
