Re: stepper motors missing steps

Hi,
What voltage are the motors rated at. What amperage are they
rated at. What kind of stepper drive are you using, what is your
motor power supply voltage, what is your acceleration rate in
TurboCNC, and finally what is you max speed rate in the TurboCNC
parameters? A little more info might be helpful in trying to resolve
your problem.
