Mike,
Point well taken. Right now, I'm milling PC boards using Eagle CAD
and the pcb-gcode ULP script for Eagle. It doesn't generate oword
statements,
only simple inline G-code. So hopefully I won't run into any trouble.
On a more general note, being able to "touch off after a tool change" seems
to me to be a necessary function for any and every milling operation. Why
doesn't EMC2 have this feature built-in? Or, to put it another way, how are
users of EMC2 currently determining the new z offset after changing tools,
assuming they don't use a probing feature? Just curious.
Tony
