Terry,
Well, my understanding is Mach3 tries to be Fanuc-compatible, so I guess that's what I care about. I have Peter Smid's book, and I've done reading in other places. What I think I've concluded is that G92 and G52 both manipulate the exact same internal offset registers, the main difference being that G92 is more-or-less an "absolute" offset, while G52 is more of a relative offset. So you really, really, REALLY should NOT mix the two, which means that if you want to use G52, the only "safe" way to set your initial work offsets is to first zero all the G52 offsets, then use G10 to set your fixture offsets using G54-G59, and THEN you can use G52 to temporarily offset from there. Is that consistent with your understanding?
BTW - I am just about tearing my hair out trying to get the KFlop to work on my mill. Much of it works just fine, but it's those last few details that are driving me nuts. And for some reason, their controller app, KMotionCNC, is completely unusable on my machine, and I don't have a clue why. Works OK if I run it on my laptop, but when I run it on the PC on my mill, as soon as I enable the KFlop, all four axes start jogging, and never stop. Mostly works OK using Mach3, though there are still issues to be sorted with probing and spindle control.
OTOH, I got an Ethernet SmoothStepper today, and it worked pretty much on the very first try....
