If you was to write a pot on the spindle controller, you should have 3 pins on the spindle controller to attach to, what are those? Likely a good candidate for the HV supply side (and the pot input)

Sorry, reading on phone during demo at work, can’t review the full thread here. What is the spindle controller model?
