Re: beginner need help with CNC Pro

Two circles, both with centers at 0,0,0. First one 1" dia., second
one 2" dia. First contoured inside ccw, second contoured outside cw.
Both with a .25 endmill, max plunge .125"

Colin,
this is a VERY simplified example of what you asked for. No feedrates
or retract height, straight plunges, no lead in.
You would want to put feedrates in if you actually use it.
