Probing - must be doing something wrong

[AxelKay]

I have the same probe and I can't figure out where to input the actual height dimension of the touch plate/thingy.
I've measured 19mm in height.
Everything else works fine and the bit stops and goes up once it touches it. The problem is uccnc doesn't guess the probe's dimensions of course and I end up having the bit crashing onto the spoilboard.
Can you guys help?
Thank you

Do you use the Probe button which calls the M31 macro or the Start probing button on the probe screen?
