Im going thru the same problem with my pins.
First of all quick intro,I have never used a cnc machine of any sort before this.I bought a mill already converted from a local in town.Before I got to actually use it,the cpu that I got with it went out completely.With it went all the settings for these motors and who knows what else.
I went out and bought a new cpu tower,installed a PCI card to have the parallel port and have been reading the PDF manual on mach 3.The driver test checks out fine now but I still cant get any motor movement.
Here is what info I do know on this machine setup...
-Keiling 9082 stepper drivers -
