G76 doesn´t work right

Okay, so, if i understand right:
I add a 1 PPR (for indication?) to phase Z, the 62 PPR stays A and so i get the second option you listet? The tracking will be better then with only 1 PPR.?

Yes, the tracking will be better because the spindle position is updated 62 times per revolution
rather than just once.

With 1 PPR you basically have to guess the spindle position by using the velocity calculated from the
previous revolution and the time from the last index ( That's what position-interpolated is )

Using position-interpolated may still be helpful even at 62 PPR, especially at low speeds
( so you avoid noticeable steps in the z motion )

Okay, now i got it. I will try to improvise a 1 PPR encoder and test it.

Very much thanks at this point!!!!

That´s it! My improvise mounted sensor works and a thread was never that sexy before

Thank you!
