Hi All, I have an Acro 1510 that I recently set up and the steppers get quite hot after an hour of use. How hot? >> about as hot as a mug warmer... too hot to hold for more than a few seconds but not hot enough to soften the acrylic gantry plates Do I need to adjust the current going from the blackbox controller to the steppers? I'm currently running it with the defaults. Thanks!
