So since early this year ive been using the novamill with my steppers wired through the 96pin connector and a 25pin parallel port header via mach 3. The spindle is hard wired with a potentiometer for speed adjustment. (id like to addess this at some point too) in my latest research ive been struggli...

Would a way to make it work manually be to give 2 and 3 10v DC and control from 0 to 10v via a potentiometer. Or is there such a board to do this through Mach 3?

The board does power up. I wired a jumper wire where the wires labeled 84 and 85 connect to the board and control that with a switch. But only get one constant speed. Forgive my lack of knowledge but I do not understand the last question pertaining to the analog signal to 2 and 3. Being that I don't...

Just out of curiosity could you help get me get my spindle working. I have motion in xy and z just trying to get the spindle fully functional now.

I have a novamill that I have decided to get going using Mach 3. I was able to get the x, y, z axis moving via a din connector on the 96 pin after pulling out the (denstep board) not sure if that's correct.
