      My setup:
      1 6HC - @ 3.6.0-beta.4 (was 3.5.4)
      3 3HC - all @ 3.6.0-beta.4 (was 3.5.4)
      System has 13 stepper axes across the 4 boards (X, Y, Z, A, B, C, D, W, a, b, d, e, f)
      System is set to CNC mode M453. This is a non-printer application
      RPi 4, 4GB in SBC mode

      All of my prior identified issues with 3.6.0-beta.3 were resolved with 3.6.0-beta.4.

      The new issues may have been in prior betas, I just didn't get past the original CNC mode issues in beta3 to discover the new issues.

      New issue #1:
      When homing any axis or all axes, the DWC re-racks the axes above 6 (so 7 through 13) on the Dashboard display and the Machine Position header.
      Here is a screen grab of the issue:
      Duet Home All.mp4

      New issue #2:
      The multiple motion systems feature is no longer working (or the required coding has changed).

      This code in 3.5.4 works without issue:

      M400
M598
M596 P1
G92 'F0
G91 G1 'F180 F4000

M596 P0
G91 G1 'B90 'D-0.8 F22000
G91 G1 'B90 'D0.8 F22000
G91 G1 'B90 'D-0.8 F22000
G91 G1 'B90 'D0.8 F22000

      In 3.6.0-beta.4, it faults on line 8 and I get Axis 'B is in use by a different motion system message.

      My movement queue is set up with:

      ; Set motion system queue parameters
M595 P100 R50 Q0            ; set motion system queue 0 to 100 steps
M595 P100 R50 Q1            ; set motion system queue 1 to 100 steps

      It seems like any time I try to switch between motion systems, I get the error when referencing any axis. I always call M400 and M598 before M596.

      I reverted back to 3.5.4 to get my system working again.
