You may need one of the G10 variants in your macro.

Or possibly just a G43

Hi andypugh, jc2ktr shared his working setup, but here is mine:

Thank you for the response,

I am using Axis gui with version 2.9.4.  I was using this format (debug,#<5081>) which yielded ######.  Upon your suggestion I tried this format (debug, 5181) which yielded the number in the var file....a big thank you for that clarification!!!! 

I think my main problem is that my tool table is not updated based on my 5063 variable.  When the probe trips the switch, I see the var file up updated, it stores tripped the z value in the 5063 variable, but that number is not populated in the tool table.  As a side note, I did have to add the 5063 variable manually to the var file.

Again, thank you for you time
 

It's pretty much the same. It's actually fairly straight forward once you get the hang of it but I guess that's true for everything and I must have made a couple dozen sim models by now.
ProbeBasic has machine simulation that can be setup using a yaml file (similar to what some CAM systems have) but it is quite limited compared to vismach.

 

Your kinematics setup seems to be wrong:

Should be 5 joints and probably XYYZZ

Just a reminder (it's way down the list of repos now) but we did previously use pi-gen to make LinuxCNC images.

Bitrot has probably set in, though.

There is a motive. My 2.8.4 has a jitter in the range of 2000. It also uses the compiled module "curve geometry" (compensation of the position of the X coordinate depending on the position of the Y coordinate). There is no such module for 2.9.

I don't think that "curve geometery" was ever a built-in LinuxCNC component. Did you install it from a comp file? 
If you have the .comp file then it will also work with 2.9.x once installed, but if you don't have the source file then you may be a bit stuck. 

If you have 2000ns jitter then you may be using the RTAI kernel? It is possible to run LinuxCNC 2.9.x with RTAI, but it's been a while since I created an installer package. (they have to be built by hand, as the buildbot currently has no RTAI builders, and it needs modifications to the Makefile) 
Having said that, I have a PC that gives 3-digit latency with both RTAI and Preempt-RT. it appears to be entirely random.
