why when code 12.1 is enabled, the machine no longer works in mm / min but in feed for revolution?
Making all movements before the code in mm / min, immediately after reading the G12.1 it changes.

G12.1 turns on Polar Coordinate Interpolation and that is output in deg/min, if I'm not mistaken. There are some other threads on this topic in the last few days. Perhaps do a quick search and see what info you can glean from those
