Slow start from LinuxCNC when adding Probe Screen V2.8

HelloToday i want to add the probe screen to my machine.After reading and adding flowed by the tutorial github.com/verser-git/probe_screen_v2.8  )
LinuxCNC is verry slow and even not response on any button on the GUI.I use the gmoccapy interface.Have anyone the same behave or any solution?
Even the probe screen is not visible on the GUI. 

Try to start your config from the terminal and see what kind of error messages you are getting there. This is the most likely to give you a hint of what is not working.

[edit]
Depending on the version of linuxcnc you may have issues with probe basic not being updated to python3:

Thanks!
After some modifications a got u GUI! And the Z axis is moving and measuring!
Now when i try to measure an tool (M6) i got the error: "Named parameter #<_hal[probe.use_toolmeasurement]>not defiened"
What do i wrong?

Seems that maybe the hal pin 'use_toolmeasurement' does not exist. Check the terminal output for more information.

I found this setting in preferences file...
But the error is still there. 

I can confirm this bahaviour as I try to implement probing as well.
Had the same issue with Gmoccapy + Probescreen 2.8
It seems to help to start out with an earlier version of the Probe Screen for the start (V1).
This starts quickly.

Will research a bit more how to get Probescreen V2 or V2.8 running and update here.
