rigid tapping g33.1 isnt working spindle isnt sync

also im not sure if it maters much but if I put in g33.1 z-0.65 k0.08 without starting the spindle I get an error "spindle not moving". how is it guys are getting the "electronic gearing" synchronized motion by hand, just spinning the spindle by hand?

I think that the software checks that the spindle is on, rather than if it is actually turning. So if you put the spindle in neutral or turn off the VFD you will get the behaviour that I suspect you have seen on YouTube.
(If you are talking about the lathe threading video then I think he simply has the clutch disengaged(

Do you see index-enable set and reset?

I will check but I wasn't sure I would see it as I just thought it would happen so fast I wouldn't be able to catch it. Am I wrong? Im not certain if it should stay in reset for a whole revolution or not.
