duet 3: z-endswitch, 2 z-motors and bedleveling using dc42

[spllg]

hello,

using a duet 3 it seems to be hard for me to figure out how to use a single dc42 for z-endswitch, leadscrew adjustment and mesh-bedleveling. i think, this should be possible somehow.

is there anybody to give me a clue how to do this?

thanks in advance
