It looks to me like the mesh bed compensation is going on a total roller coaster ride. Can you disable it before homing

@Rollux
try this as homeall

Can you take over the code with copy paste for homeall that I posted here?

G1 H2 Z5 F6000               ; raise head 4mm to keep it clear of the bed
G1 H1 X-450 Y-450 U0 F3000 ; coarse home X, Y and U
G1 X5 Y5 U-5 F3000           ; move 4mm away from the homing switches 
G1 H1 X-400 Y-430 U0 F600      ; fine home X, Y and U
G90 ; absolute positioning
; Now home Z using the Z probe

@Proschi78 Will give this a try tomorrow, unable to connect to the printer at the moment as having internet/router issues and pc vs printer location makes ethernet connection not viable.

Tried the above and the movement behaviour became consistently erratic. Not sure as to why. Reverted back to the below and seems to be have "settled" to a somewhat normal behaviour. Potentially might reset the mbh6c and expansion board back to square one. Potentially the firmware updates may have left some things stuck which shouldnt be the case but never know as all the boards were still on 3.2 beta firmware when started up this time round.
