I have a X3 controlled by a c11g. Per Johns instructions,
http://cnc4pc.com/Tech_Docs/C11G_&_S...0storybook.pdf, I bought a 12V to 12V converter to avoid needing another power supply with a separate ground. #NKE1212SC and the datasheet here:
http://www.cd4power.com/data/power/ncl/kdc_nke.pdf
I have wired the converter as it is in his instructions but have not wired the direction of the spindle through the electromechanical relay (pin 16) yet. I figure that I should get the speed control working first, using the direction control on the machine and then after that's working, I'll get to the direction control setup.
I believe I have everything configured correctly in mach3, mainly spindle control enabled on pin14 and the motor tuning but really I don't know and to be honest I don't know how to turn the spindle on in mach3 even if it is all setup correctly. I've been playing with the spindle speed box in mach3 but maybe there is more to it?
Thanks for the help guys!

I did mine the opposite, I did the on/off and then the speed control. I figured that the on off would be easy and if I couldn't figure out the speed control right away, I could just run the speed fom the pot on the vfd.
You are on the right track by using a volt meter, I get 0v at s0 and 10 volts at S100. Using MDI for testing it with it disconnected from the speed board. If you can't get 0-10v with the meter, it sure won't run the motor.
On my machine, I had to put pulley settings in to get the correct voltage/rpm, but I am using the dspmc board and not the pport. I don't know if this will make a difference.
Under configuration go to spindle pulleys.
I put in min 0 max 100 ratio 10 on pulley1.
If it helps let me know.
