No, not that I could see, but I don't think you intended it to be used to
carve a recess 0.003" deep and 1.70" in diameter. Worked just fine once I
found I could save the file & add the m3-m5 stuffs and the % sign at the end
to shut the interpreter up. Having all those presets available sure makes
that a handy utility code generator. The biggest problem was my out of
square vise, but that's just another excedrin headache, nobodies fault but
mine for not checking it years ago.

It could also do with some o-word subroutines, which could shorten the code
considerably. I have one I wrote that uses them, 2 nested subroutines and is
only maybe 40 lines, but I have to fool with the editing, while tryng to
remember what this var does where, and yours is much easier, just fill in the
blanks, save it and reload it into axis, done. No broken bits or carved up
fixtures, it just works, although I had to get out of the habit of entering
the stepover in inches. Duh...

I hear that! Too often, taking the time to do it out of the days work
schedule seems to take all the profit out of it. OTOH, having these
available can give you time to do something else, so it should on balance
help at the end of the week if it takes 2 hours to code & debug something
that then frees up 6 or more hours while its running essentially lights out
and you or I can go mow the grass or work on another part in the lathe,
whatever. I know I'll have to pull the mower out and gas it up in another
week, or get a machette to get to the shop. :) And its drizzling at nearly
freezing here this morning, again.
