Odd problem with a router running mach3
At the end of a part program the cutter retracts to z.8 (zero set on top of the part) and then the program sends the machine to x and y 0.0 (lower left corner of the material) and then does a m30 to end the program.
If you look at the DRO when everything is done the Z is sitting at -1.7, which if I change to machine co-ords is what it says it should be while the x and y show the offset where the material is (3 and 3 in this case)
So it would appear that somehow at the end of the program it is resetting the z axis back to the machine value or erasing the z offset or something, but not affecting the x and y
I thought it might be from the router turning off but since it's not some random number I now think maybe no.
Z zero is being set with a tool-sense plate if that makes a difference
Any thoughts?

Look in Gen Config and see IF you have any of these checked.

I ran several parts today and after each one the Z value changed but not the same each time, I originally thought it was going to machine value but it doesn't seem consistent, it's changing each time, always on the z and always right when the program ends, after it goes to it's x/y zero
I checked the general config screen and they have "perform G92.1", "Turn off spindle" and "radius comp off" all checked
What exactly the perform G92.1 do?
Thanks

(;-) UNCHECK them. I would leave on turn off all ouputs.
