I've heard that BASIC has come a long way. Motion control can
definitely use in-line assembly. I just spent a week doing inline code
in Borland's C++. Just to speed up some data xfer from a FIFO, and Queue
up the triggers found ('scope application).

For simplification, how about a "minimum tool kit recommendation" for
new CNC programmers. I see an opportunity for someone to write a USEFUL
CNC book for the uninitiated. I bought two books, didn't get much out
of them. Better to just dive in. Ha! I probably need one on CAD too!

And we appreciate it.

Missed getting the "blue". Got the white, very granular. I'm moving on
to scraps of wood. Biggest problem I have now is trying to setup the
part on the Sherline. I run out of room! I'm trying to use the mill
vise, and had to turn the part to match the x axis (must be a rule
there).

With G41/G42 off and removed, I can cut the contour and bore the big
hole. I found my stash of end-mills from about 10 years ago, thanks to
an old friend at NASA. Even two ball-end mills.
