There seem to be several issues here. This is the way to go about with a new setup:-
Start the steps at 400 on the drive Set the Step per unit at 200 in Mach Set the velocity to about one third on the slider in mach Set the Acceleration to about one third on the slider in Mach. Apply at least 36v - 80v supply to the drives on the VM pins. Anything less than 24v will deliver nothing. These setting will be corrected as soon as you are in a position to calibrate the machine so don't worry to much about them now. If you can't get the motors to turn with these setting then something else is wrong. If the above does not produce results, I would think about the pins that are used (not normal in this case) On 2013/09/22 11:41 AM, Gregg Eshelman wrote: > On Sun, 9/22/13, Marius Liebenberg <mar...@mastercut.co.za> wrote: > > Subject: Re: [Emc-users] Very weird thing with my stepper motors.
