How do you prevent a head crash if the pin is up and you are trying to home?

Hello. I have made a design like yours but I couldn't find how to configure marlin for the auto bed leveling. Could you please tell me a way or give a link about it?

Hi there, I am struggling to find info on optical switches. Can the switch detect filament even through a PTFE tube?
Kind regards

This are the same optical switches I used.

I don't believe the IR light would pass the PTFE or the filament(Besides I don't think the space betwwen the emitter and the receiver is big enough). For my design I used an Allen wrench to trigger the switch.
