The hot end of my MakerGear Stepstruder won't heat up.
I just finished assembling my MakerGear Prusa Mendel kit. I loaded my RAMPS 1.4 up with Sprinter and then calibrated the steppers with Pronterface. But when I use Pronterface to turn the on the heat on the exturder, nothing happens. I can heat it up manually by hooking it up to a power supply, so it
can heat up. I'm also using an ATX power supply.
Anyone know what could be wrong? RAMPS just isn't sending any power to the hot end, (I checked with a multimeter) and I'm out of ideas as to fix it.
