I have the pro board and 3 305oz steppers. Everything worked fine before the
rebuilt. then the Z axis would hang up on every turn so I replace the stepper
and it worked flying fast with a lot of power, but now after 10 sec the driver
will stop working. At first I would last about 2 mins but now it starts to shuts
down after 10 sec.
I tested the volts at the motor and have 0 volts....Would this be the IC chip or
something else and did the bad stepper blow the chip?
This is a video of the new built doing over 1000 ipm on jogging it around.
