General Mach Discussion / Stepping only in one direction
« on: February 15, 2016, 02:42:01 PM »
Hello,
I am working on converting my table top mill to a 3D printer. I have ran into some problems with the A-axis and would like some help. The mill is running Mach3 and has 3 steppers that are working fine running off of 5056 Micro step drivers.
The A-axis is running off of a Longs-motor DM420A Microstepper driver.

I am running the driver strait from the parallel port.
The problem that I am having is the stepper will only turn in one direction no matter what I try.
I tried hooking it to the leads that are running the other motors and still dose the same thing.
Any help would be appreciated.
Thank you
