How to work with Wrapped_rotary axis? was created by aleksamc
I supposed that configuring axis A to wrapped_rotary=1 will be good idea. But I found many inconveniences with operating it:
1) I can't make full spin in 360 degrees with such gcode G0 A360, G360 is non-existent coordinate. I need to type G0 X359.999 and then type X0. It would be nice Idea to add A360 degree to program.
2) How can I do few rotations in one G-code line?
If I need to make 3 rotations in Wrapped_rotaty=0, I simply typed G0 A1080 X200.
How to make such movement in Wrapped_rotaty=1?
I'm sorry if I wrong in my bad knowladge in this question.

OK, after some testing work with rotary axis I see, that working in G91 will solve my question #2.
But mode "wrapped_rotary" is hard to use in G90.
For example If I set in A10 and I want to move to A5 degrees in a short way, I need to write A-5, because if I write A5, I will move to A5 in positive direction through 360 degrees. I always need to take in mind, what direction I need to move.
I don't say that it's wrong, it's right and it can't be in another way.
As for my first question, when I type A360 I get error "Invalid absolute position 360.00 for wrapped rotary axis". This messege irritate me.
I think, it would be much better if EMC understand A360 as A0. And If I'm in A0 position and Typing A360 (or A-360) I make one spin instead of messege.

There was discussion of this many many years ago and I can't remember the details. In the end they added wrapped_mode.
You could add a feature request to get the discussion going again.
I agree it's annoying.
Programmers and machinists see things differently sometimes

I found
wiki on wrapped_rotary
and it dated to 2009/01/16 by JeffEpler.
Forum search founds only 2010 year old posts with "wrapped rotary" so it was very old post.
So possibly I think it's impossible to renew that thread.
Currently I don't know any PostProcessor that will succesfully work with wrapped rotary axis. So I think I better turn it off.

As I know no progress. I solved my task other way, with default, not wrapped settings.
