How do you unwind the A-axis on Haas?

[Gracjan aka Pullo]

on Heidenhain you issue an M-code to reduce the angle to a value between 0 and 360 and then turn the angle to 0. I could not find a code like

that for Haas.

G28 G91 A0.

With G91 G28 (rotary)0. (Could be any "rotary" address, depending on machine configuration). For example, on a UMC machine, G91 G28 C0.

But, Setting 108 "Quick Rotary G28" must be ON. Also, you must use G91 Incremental mode, with the G28.

(Don't forget to command a G90 afterwards, to put your machine back in Absolute Coordinate System!)
