Any z probe that only occupies Z Probe connector port?

I don't even know whether the BLTouch will drive a Duet endstop input. I have not seen any documentation describing it the drive capability of BLTouch, and there are multiple versions of BTouch and its clones. So I can't recommend using an endstop input for BLTouch unless you use a logic gate or transistor to buffer the signal, in order to guarantee meeting the pulldown current requirement of the Duet endstop input.

Also bear in mind that next time we revise the Duet WiFi/Ethernet, we will probably expand the Z probe connector to be 5-pin so that a BLTouch can be connected to it directly, as it can on the Duet Maestro.

@dc42 I would enjoy that. Not a fan of nor hater of the bltouch, but it's what I setup first, so unless I have a big reason to change it out, it will stay.
