770 lost Z tool height

I’m not sure if this should be in the pathpilot thread.
I have a 770 that I use the Hallmark ittp probe on, I have a tormach probe that hasn’t ever been used with the 770 that is in the same tool rack, and accidentally use it to probe a bar for 4th axis. X and Y are good, but Z tool height has changed. ended up with Z about .800 above the 4th axis bar stock.
I reset the spindle height with a 123 block. Z tool height was now below the 4th axis bar stock.

Thanks

Well, It seems to have fixed itself. I don’t even know how.
When running the program for a 4th axis bar, the live axis display now shows the bar larger than it used to and the tool is inside the bar.
