Late reply, sorry. Been carving code & nursing my back. I have it about 80% working, and it looks like it will in fact work well. But I separated the TLO function and the top/bottom offset function, using G43.1 z# to apply the TLO, then for the X offset, setting G10 L2 p2 #result from hole probe, then switching to the G55 co-ordinate system to do the bottom side work. I say about 80% because I need to find some carbide drill bits in suitable sizes because an HSS drill bit seems only capable of drilling about 10 holes halfway through the board without getting so dull the copper is burred up for 5 thou around the hole. Topping that off, I used a deicer repair kit to add some robustness to the registration hole, which worked well, but when I was working on the same function for the bottom of the board, a ^%& typu drug the probe sideways about 20 thou, wrecking the hole. The rest of the board looks well once the burrs were polished away, so I've set the G54-55 stuff up, and left it running, and will see if I can iso-etch the bottom tomorrow and have one usable board. I have more pcb material I can cut, but I'll have to find some more better drills to do any more of them. For stuff like this, it seems I should just buy an index of #10 to #70 carbide drills, but so far all I have found in the catalogs are TiN HSS stuff. Anybody here know of a supplier for carbide drills in teeny wire sizes? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
