If you mean by M1xx routines, I have considered these to be a temporary
fix. I would like real CNC machinists (not me yet) to be able to use my
machine and be reasonably comfortable with it, with knowing very little
about EMC. With as few "yeah but"'s as possible. One unavoidable problem
is that even the G codes are not standard. Maybe a new standard code
should be pursued. Is NML a standard? Could it be used for part
generation files? Or just adopt a HAAS or other code set? (I think one
of the passed suggestions was similar to - "who cares, you can do what
ever you want", which is valid too.)

I don't mean to be critical, but I consider this to be an implementation
of macros, which is cool, but doesn't address the problem of some
missing basic codes.

(By the way, whenever I seem to be expressing an opinion, usually that's
not the intent, but rather I am exploring whether I understand the
issues correctly or not.)
