I had several profiles, but only the default was working with M3 commands. All other had this same issue so seems like they were corrupted.
The profiles were all originally created in a eralier version of UCCNC, except the default profile, to which other settings were loaded and applied, and luckily that seemed to work. (I just installed the latest version of UCCNC on a clean windows installation).
I recreated new profiles based on the default, and now its working correctly.
Not until I had reinstalled latest version of UCCNC I read that profiles created in previous versions of UCCNC should not be used with newer versions, so I had not saved screenshots of all settings.
Mmm, I've always kept my original profiles, they're very simple though.
Did it say at which version the cut-off was?
How are you meant to update and reuse current setups if you shouldn't use your old profiles?
I can't remember which version I changed over from Mach3, but it was a lot of years ago.
