Inconsistent values from Versaprobe

I'm sorry but this does not work for me as described.

Few have chimed in(thanks for those that have), does anyone have VersaProbe working as expected?

Can you share your ini file and tool change macro ? 

 

Sure.
The attached qt_auto_probe_tool.ngc file has been altered however, I can use the same file that comes with the master
and there are no differences in the outcome.

In the ini file the reference to this line was added by me per another thread here .
# This is the MAX Z travel to my spindle chuck without a tool.
Z_REF = -183.97

Of particular interest, is that after I add my probe tool Z offset, it gets removed somewhere during the procedure.
It was:  T99  P99  D+2.000000 Z0 ;3D Probe
It's now:  T99  P99  D+2.000000 ;3D Probe

Thanks for your help, can you share your probe NGC file?
 

Can you try to replace this 2 lines from

to

I just realized, there is something missing. You need to know the distance from   #<_ini[VERSA_TOOLSETTER]Z_REF>  (-183.97) to table surface. This must be added to toollength. Then you can work with table as base.
I think the toollength probing result you get now, is wrong by exactly this value.

I will measure this from Z0 to table top but, what's the VAR that I add it to?
