Tool offset

Hello. Have a problem here. Seems it came with last post processor, I use Fusion 360 for designing and generating gcode.
I touchoff, run gcode, after its done, run x0 y0 z0 command, and Z is 1 mm higher that it has to be.
I run code again, same thing, on third time, Z height is where it is supposed to be.
Then I noticed tool offset on Z and I cant change anything on gmoccapy (cell cant be  activated to change value).
Where does this come from and how can I fix this?
Thank you and Merry Christmass! 

A lot of things can be going on. The biggest thing to check is what offset value are you running the x0 y0 z0 command in? You should be able to see this in the bottom left of the screen. Is it possible that your touch off is in G54 and then some part of your gcode is in G55 etc? Its also possible that your code added some offset with something like G92.

To figure out more we would need to hear more about how you are touching off and what your code is that you are running.

And this is for sure not gmoccapy related!

Sorry for wrong section. So, can I change value in tool list somehow?
