The steppers are working just fine for my X and y axis, but after adjusting the POTS for power on the Z axis motors, both failed within a day of each other. the other three are functioning just fine. They are randomly jumping from .1 volts to 2.2 volts on out V+ channel. Luckily it doesn't look like any damage to by steppers. I have put in the old 4988 drivers for the Z axis. Much louder, but they are working!
