Z probing pin question
I would like to make a Z probing on my boxzy for CNC and Printing.
My question is this one.
If I put a ground on an aluminium sheet on the building plate and connect the bit router or printing head to the board, this will work as a switch maybe with some resistor.
But I didn't find where to connect it on the board except on a switch limit.
Do you know some free head on the board and their number on the mega or I need to connect directly on the mega.
Is this a good question?
