That is I believe, a new one to me, thanks Ed. I'm assuming that will alleviate the need to actually edit in the moves to the tool change position. OTOH, pcb-gcode outputs those moves too, so a slight change in its recipe and I am down to adding the subroutine call after the M6 T# > Then M6 will move to the G30 position, which you've cleverly set right > above the probe switch.

Which I now think can be a file to the call function, a single line to insert. This is sounding more better all the time. > The sourceforge pcb2gcode page has a bullet item: > > output can be adjusted for automated height probing, see > http://www.cnczone.com/forums/showthread.php?t=82628 > > That discussion points to: > > http://www.cnczone.com/forums/pcb_milling/82628-cheap_simple_height-prob > ing.html I haven't looked yet, been out all day but I know it will be useful (Dr's office & 2 or 4 craft stores, Dr says nose is ok, just not 100% healed yet), thank you for the pointers to a recipe. > Which seems to be a generalized planar-surface probe process that's > likely too complex.

VBG & a Chuckle :) Where I have the problem of doing much of it from scratch, first learning eagle (if it can ever be said one has truly learned it), then learning what little I know about pcb-gcode with the same comment. The gcode being virtually the only thing in this whole sequence that I haven't had to learn completely from scratch although I have spent quite a bit of time looking for fixes I needed _this_ time. Its been a fun ride even if i have hit a pothole or 3 that folks here have at least told me where to get the 'bag mix' to fix them, smoothing the ride. Thanks.
