Hi all
I've bought a 3d touch and mounted it 3mm above the nozzel with the pin up. Flashed with Marlin 2.0 by vert.
The probe appears to be working in self test mode but when homing it crashed into the bed.

I'm sure I've mounted it wrong or missed a step somewhere.
Can anyone offer any advice.
I thought I say a good vid for it but all the ones on you tube I can find are a bit rubbish.

Thank you.

I've resolved my issue.
I mounted it too high and also had a blob of plastic on my nozzel. Rookie mistake.
I had to alder the z offset which is really nice in marlin 2

That's good.
