Hello Everyone. My name is George Merzbacher
I built my own cnc router table and am currently trying to get the mach 3 to talk to my VFD for my spindle.  I have no experince with CNC but just one day i was searching the web and came across a build it yourself cnc.  started doing research and after a time i started building.  I think i have the spindle configured corectly but cant figure out how to try it out to be able to check my voltage at my breakout board. I get 0 volts and when i toggle in Diagnostics I get 10.20 Volts but how can i check it like at half RPM to see if im getting 5 volts?
