I'm trying to send step/dir signals to a cnc4pc C6 spindle control board and am pulling out my hair. I have the spindle motor output set to pins 8 and 9 and the C6 board connected to these pins and it just sits there, nothing. I tried all kinds of different combos of low active, etc and nothing works. I have it set just like the C6 instructions say too.
I connected the step and dir connectors on the C6 board to pins 2 & 3 (x-axis) and it seemed to vary the voltage (0-10v) just fine when I moved the axis so it seems like the spindle command in Mach3 just isn't sending a signal to pins 8 & 9 for some reason.
Ideas?
