Re: code generation?

Yer welcome. Let me guess--"Z0.10" lifts the endmill .100" [assuming
the machine in question regards 'up' as increment-z and not
decrement-z] at the end of thelast cut so it doesn't try to trench the
workpiece during the rapid-traverse return-to-home, right?

Such is the price i pay for using CAM-generated code from a quick .dxf
sketch with thickness=0.

Is there one book, a 'for dummies' or something, that pulled together
the basics of CADCAM in one resource? I've concluded
information-overload is the single biggest problem here...with demos
of 12 or 13 different things on my 'puter at once, too many choices...

thanks
Lurch
