Let me try to explain the system better, when say the arrow keys I mean the Mach3 up and down keys located below the spindle button on the Mach3 screens,
When I press the Mach3 Spindle switch the relays on the BoB comes on and the spindle works fine, the problem is I cant figure out how to calibrate the speed to match.
The system is using step / dir not PWM, the wiring is through a RS485 USB adapter to the VFD and then to the PC, I think its working ok.
Example:
MDI = Enter S500 the spindle runs 1312, S1000 the spindle reads 2655
I need help with the right procedure to calibrate the spindle
Thanks for you help and patience
