        I'm afraid I don't understand what you're asking.

          Hey i understand him. I think you want a switch for the different length of your nozzles. I am searching for the same thing.

          This is a good way to start. He use parallel the bltouch. So it is a second z endstop.

            I have a tool changing system on one of my machines.

            In that, I reference and level without a tool loaded, then have Z offset for each tool in the tool configs.

            Once set, they should never need changing, or at least until you replace a nozzle.

            To calibrate them, I just set the Z at zero in the tool initially, pick it up and measure the height the nozzle touches the bed, then put that value in the tool Z offset; done.
            Check it prints OK and adjust the offset fractionally if it's not perfect.

            Accurately calibrating the X & Y offsets to be able to do multi-material prints is much harder - I've not done that so far, I'm still doing other tweaks on the machine.
