gmoccapy - tool change and edge finder do not work

Hallo, I installed LinuxCNC 2.9.4 with gmoccapy 3.4.8 on my 3 axis mill (router).
While I can operate (home all 3 axis and move manually and by NC program) the tool change (and measurement) does not function.
When I click on the edge finder button at the bottom of gmoccapy screen, nothing happens.

I would like to debug and find out what's wrong on my setup.
How can I trace what gmoccapy is doing? What should it do when I click the edge finder icon?
Does gmoccapy call a macro? or another program to execute?
Hope for help

If you want find out default behavior, you should try sim (simulation) configuration of Gmoccapy:
configs/sim/gmoccapy/gmoccapy.ini

Is it your first instalation, or did you upgrade from 2.9.3 to 2.9.4?

Here is manual:
linuxcnc.org/docs/stable/html/gui/gmoccapy.html

Here is source code:
github.com/LinuxCNC/linuxcnc/blob/2.9/sr...gmoccapy/gmoccapy.py

thanks for the reply.
It's a fresh installation of latest gmoccapy version.
I'm not a software guy, but followed the manual as much as possible.
Have no chance to dig into python stuff.
As mentioned, referencing the axis, MDI, already works. Even macros.
Its the M6 what does not work..

May be you are missing parts in your config.
Post your complete folder.

I am not sure what the edge find button is.

I am assuming that your router needs to move to a certain spot for the tool change. Look into tool change at G30. Make sure your program retracts the Z high enough before every tool change. 

If you have an automatic tool changer you will need to remap the M6 command.  linuxcnc.org/docs/html/remap/remap.html#...lated_codes_t_m6_m61
