Posted · UMO+ burning stepper motors and brownish board

Hi everyone!

Since I got my UMO+ the stepper motors get really hot when they're working (I can't touch them for more than a second without burning). Two weeks ago my heated bed sensor died, and when I disassembled the board cover I saw that the the board is brownish (burnt) around the X,Y,Z and E1. On the picture you may not appreciate them very well, I just didn't want to photoshop the picture to give a wrong impression.

Is this normal or is there any risk something fails? I checked everything, but as it's the same board as the UM2, the power sent to the stepper motors can't be easily changed.

    Btw the power sent to the motor it's very easy to change it by Gcode on UMO+/UM2 with

     

    M907 X(NUMBER) Y1(NUMBER) Z(NUMBER) E(NUMBER)
