Thanks Graham - I really wish the problem was simply me being a complete idiot, but it isn't. NO I'm not setting a new zero in mid program. I don't even think you can do that, though I've never tried. I'm running a program twice. Running it once in one work offset, letting it finish completely, jogging over to the next position that I want to run the program at, setting zero there, and running it again there. Never have a problem on the first run, usually don't have a problem on the second, but many times I do. I don't know what happens on the third time I try it, since after the first screw up, I just shut everything down and start back up again.  Anyway, the behavior sounds like its the same thing as described earlier in the thread, I'm trying to shed some light on when I think it's occurring most, so maybe Warp9 can have a little light go on that says "Snap! Of course! I have to clear that buffer and send those new values to the registers every time the program is started!" Or at least wishful thinking.

What if you set up the offset in G55 and just MDI G55 for the second part?

Setting all the offsets beforehand might not be a bad thing to try. From a Smoothstepper hardware / firmware point of view, I wonder what that might prove? Perhaps I'll try it.
