Incorrect object model / status when multiple drivers on Z

When requesting a http://ipofprinter/machine/status, it incorrectly shows drivers from 4 upward as being part of extruders, where 4 and 5 are actually part of Z. Here is a tree view of part of that response:

I noticed this while trying to reverse the first extruder.

M569 P6 S0

and

M569 P6 S1

Show no difference on the extruder itself.

@Danal said in Incorrect object model / status when multiple drivers on Z:

Your M569 commands for expansion boards are wrong. They should be e.g.:

; Expansion 0
M569 P1.0 S0 ; Drive 0 direction | Extruder T0
M569 P1.1 S0 ; Drive 1 direction | Extruder T1
; Expansion 1
M569 P2.0 S0 ; Drive 0 direction | Extruder T2
M569 P2.1 S0 ; Drive 1 direction | Extruder T3

I will look into the M409 report.

I just started a system using your M584 commands in config.g. This was the result:

These look correct to me. I am using the internal build of RRF at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0 running in standalone mode.

Thank you for the M569, that explains that...! I will update.

I will also try the internal build and report back, that will be this evening Central US timezone (about 10 hours from this post)
