@dc42 Great, many thanks!

@dc42 I'm just starting the build of a printer and looking at the Duet wifi plus expansion for the controller. Is there any update on this multiple Z axis topic?
I.e. has triple Z motor drive with auto bed levelling been implemented?
Incidentally, I will need 2 x Y or X motors and independent drive, but common stepping. Is this available 'out of the box'?
