My probe (probein)is plain switch it has servo arm .

My printer as well has Z max switch.

When arm/probe at 0 degrees it acting as X min endstop.. (probe.in)(same endstop switch)

When arm/probe deployed at 90 it could act as Z min as well as probing.(probe.in) (same endstop switch)

In RRF 2.0 was setup all ok it had Z probe min ,Z max endstop switch , Z probe X min.(in other words it had 4 endstops)

How to setup in RRF 3
How a many endstops can you have in RRF3 ,
When probe z acts x min with the same input?

Thanks
