  • I recently hooked up this easy driver controller to a ST-PM35-15-11C stepper motor purchesed on this site. It all works fine buy the chip on the controller runs very hot. I am using a 12 volt dc supply and have the current limiting pot al the way clockwise. The chip gets hotter if I rotate the pot CCW towards the max setting. Anyone have an idea of what is going on?

No public wish lists :(
