What is the holdup Steve? Admittedly I have had to reinvent some wheels, and my .hal file is almost 300 LOC, but its working well enough to run the G76 for either internal threads or external, and while I see a bug when trying to write a peck cycle wrapper for G33.1 rigid tapping, that also is working for _most_ values of working. The bug is that my homing routine, which works by electrical contact with a gauge I set on the ways, with its left face touching the chuck jaws, and which also sets the left z limit about 5 thou short of carving on the chuck jaws (with that tool mounted), this limit is honored while doing the G33.1, so as the tap is being driven into the pre-drilled hole, which is usually going to be left of the chuck face, so it stops at the z limit while the spindle continues on for 1 to 4 turns, either pulling the tap in two, or pulling it out of the holder & jamming it back in. For something like that, G33.1 needs to disable the limit. Perhaps an optional argument switch could be added? Unforch, hal show config does not expose a pin or signal to allow that to be done. :( No problem as long as I have enough "stickout", but that seems easy enough to forget. Can you describe your lathe? Spindle speed & direction control in particular? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
