Its not G54.
Something somewhere is modifying the z axis.
I called T100, set the probe, zeroed my Z axis and the knee ref
Then checked the G54 and that had the correct offset in it for the z zeroNext i called T11 which is shorter, the knee lifted correctly to compensate
Then pressed start (no tool fitted) and the z plunged happily off the scale and i hit stop.
Look back at current tool pro and it showed T11 correctly but the Z axis was about 100mm off - the code was calling Z2.0 but Z2 is way off below where it can go as the numbers are so way off.
Now, i am only using #var 179 and i don't think that is connected with Z DRO at all, calling button 1010 in my Z zero macro seems to set things correctly.
I'm at a loss now as to what is going wrong, is it possible the T11 M06 call is applying tool offset internally somehow even though i have deleted ALL G43 lines from the code???
Something is messing with the Z dro I think,
Stuck now.
Edit...No it didn't, just thinking here, G54 in Z zero would be the distance from Z machine zero to the work zero??
Well its not, G54 was reading something like 190mm when the actual distance was something like 40mm
Does setting Z zero internally apply TLC to the G54 offset??
That might explain it if it did??
