      Kinematics is Cartesian, no segmentation, matrix:
      1.00 0 0 0
      0 1.00 0 0
      0 0 1.00 0
      0 0 0 1.00

      im wondering if there is some stuff "stuck" in the mb6hc cache/memory that might be affecting things?

            Increased the x value to x-450.
            Individual homing works fine when selected separately.
            Home all on the other hand is inconsistent still. During "home all", when the x axis triggers the end stop, the y axis will also trigger even though it has not yet hit the end stop. Bltouch will lower, trigger, raise 5mm then drop 5mm (not sure where else the lines of code for this are found as i have removed all i can find as i want the z axis to not drop down after probing).
            Also, the z axis moves up or down when making manual moves via the panel due or dwc. Ifeel there is something somewhere that is conflicting. All the boards were well outdated (3.3 beta from memory) as they have been sitting for a while so wondering if a hard reset of the main board and the 3xc are in order?

                Y axis doesnt move. Wont re home manually without a re boot. Reboot the board, Y axis "triggers" at the same point as the x axis regardless of position.
                Thinking will reset the mainboard and re flash firmware as something may be hanging around from all the updates and the like.

                  @Rollux If all the individual homing files work, then you could call them individually for home all.

                  e.g. homeall could be..........

                  M98 P"homex.g"
                  M98 P"homeu.g"
                  M98 P "homey.g"
                  M98 P"homez.g"
                  

                  Try that - if it works, then the problem is with your homeall.g, if it doesn't then the problem is elsewhere.

                    Success there on the first try. Then move everything around and try again. X and U axis home perfectly. . Y axis jumps and then does nothing and get the following error: Error: in file macro line 17: M98: expected a string expression.

                    Going to have a look at the y axis endstop
                    m119
                    Endstops - X: at min stop, Y: at min stop, Z: no endstop, U: at max stop, Z probe: not stopped

                    As it is one the "pcb board" style ones, wondering if it has failed but that doesnt explain why it works once or twice then nothing.

                      Replaced the endstop with a pare makerbot pcb style. Same issue. Check wiring, all is good. Hard reset. All homed perfectly, repeatedly. Then back to the same issue of the y axis bumping in the opposite direction if the end stop and failing to home.

                        "Home all" using individual axis works as expected. However, homing individual axis via dwc or panel due, Y axis does not want to work. Incredibly confusing.

                          Current homeall.g
                          This works somewhat, the U axis homes after x,y,z regardless of U axis position.

                          Also when homing z, the z jumps up and down and the x and y jump around. Video Attached of whats happening.

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

                                  @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.
