    The machine expects an active tool to be in the spindle so that you can "teach" x,y,z offsets. If no tool active, then no teaching. ?Maybe?

    Just deciding to use metric dimensions rather than inch requires much more than just executing a G21 command. Offsets and parameters as well as tool data must all be converted. Not a simple task.

    I like 300 sfm max for 304/ 316 on a lathe. The slower rpm is more than made up for by not chasing tenths, changing tool inserts.

    OP: Don't try to engrave full depth of the ball radius. I use a 1/16" ball end mill at 8000 rpm, 0.0015" per rev, but only cut 0.003 deep. Yields a width of about 0.025 Can't hardly wear it out.
