SmoothStepper USB / Re: ESS and C11G help needed

Thanks for the responses guys!
If I tell the ESS config that I want 'step/dir' spindle control then the pin mapping gets weird. In 'PWM' mode I can map a pin for the PWM signal. However, in 'step/dir' mode this option turns into 'Spindle - unused'. And while I can map pin 14 to 'spindle - unused', I cannot turn the pin on/off, much less control it's voltage.
The manual I'm following is here: http://cnc4pc.com/Tech_Docs/C11G-R9_USER_MANUAL.pdf
I've followed the manual in connecting 2x 5V signals to power the board, and connecting a 12V signal (as per page 7). There are pins for "0-10V" and "GNDA" which I believe are the variable analog and analog ground pins (these are completely separate from pin 14). I'm lost when it comes to how pin 14 is related, if at all, to these analog voltage pins.
Joe, I tried your PWM on pin 9 idea, but I can't get any voltage out. I'm probably missing something on the mach config side of things... I've set a maximum spindle speed (in 2 places on that screen), step/dir spindle axis is left as 'none'. I notice that although spindle PWM is an option in the ESS config, it is not showing up in the mach config output signals tab.
