Setup Mach3, my stepper motor howls but does not run
« on: February 10, 2017, 04:55:48 AM »
I can not get my Nema 23 stepper motor to run.
I can hear the howls but does not rotate.
I have this machine
Use this card with lp1
Running win7 32 bit
Could it be my switch on the circuit card

Is it any motor or all motors?

Sometimes when steppers howl, they are being told to move too fast or with too much acceleration - try reducing these to start with.

Also check pulse width in motor tuning, try 5us
