QT Dragon Unable to Set Tool Height

The buttons on the probing page for setting the tool height, I am unable to click on those. Ever other button works. Bottom two buttons

What version of linuxcnc are you using?

2.9.4

Can you post your ini file and preference file if possible?

Attached ini and hal

Doesnt work in sim either

I discovered that the bottom right button is disabled by default.
I didn't notice this as I had a 'hidden' modification to enable it.
It was experimental, that is why it is disabled. I could show you how to enable it, if you wish to try it,

Absolutely I would like to try it

OK
In your configuration folder (or the sim folder if you want to test there) there will be a set of folders qtvcp/screens/qrdragon/
in that last folder add the file i have provided. name it qtdragon_handler.py

When you run the config, there should be an entry in the status page about a customization.
The button should be clickable after that.

I would suggest you try the sim first.
