UMO+ burning stepper motors and brownish board

[flowalistik 181]

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.

Well mine has 8 months heavy use and definitely doesn't look 'that' yellow.

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)
