    @stevo My approach is to always keep and maintain the configuration files on my PC. Then if I need to, I edit the PC based files and upload them to the Duet. That way, I always have a working backup should anything go amiss with the SD card.
    Any text editor can be used to edit the files - notepad++ is one that I use (it's free).

            Afternoon all,
            I have edited all the files as mentioned in the previous comments,
            When looking down on the printer with the two steppers controlling x and y at the bottom the tool head travels in both negative's axis direction to the bottom left.
            I have purchased a genuine V3 BL touch and would like to connect this to the Duet WIFI 2 next.
            After looking at other posts i have more doubts than when i first looked lol.

            So without doing something i will regret i don't need to physically break any connections on this version of sensor or add resistors.
            But i need to add a Gcode to set the correct voltage for the sensor ?

              Have you read the link deckingman has mentioned ? -> https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter

              Quote from the Movement Section: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Movement_section

              For a CoreXY or H-Bot machine, RepRapFirmware assumes that the motor connected to the X motor output moves the head in the +X and +Y directions when it runs forwards, and that the Y motor moves the head in +X and -Y directions when it runs forwards.

              Then test for the correct X motor movement by sending these commands from the console:

              G91
              G1 S2 X10 F3000

              If the head moves diagonally in the +X and +Y directions, all is well. If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command. If it moves towards +X and -Y, or towards -X and +Y, turn the power off and swap the X and Y motor

              Read the whole section again and run each command to test if everything moves in the direction it should

                it sound like you are still in cartesian mode rather than corexy mode.

                for bltouch see this guide

                  I have followed Mark Rehorst's (thank you Mark) how to set up core xy origin and Endstops article origin is at Alpha motor all positive movement is in the direction of the top right pulley.
                  The tool homes back to the Alpha motor.

                    @stevo Do you have a problem with the motion or not? - I'm a bit confused because it sounds like it's doing what it should do..

                    To be clear, if you command an X positive move, the print head moves from left to right in your diagram and there is no movement in the Y direction. Yes or no? If no, what happens when you command an X only positive move?

                    Conversely, if you command an X negative move, the head moves from right to left and there is no movement in the Y direction yes or no?

                    And a Y positive move moves the head towards the back and there is no movement left or right. Yes?

                      @deckingman Yes it ticks all the boxes Veti mentioned in still appeared to be in cartesian mode guess its my poor description lol

                      Thank you

                        please post your config.g so we can have a look at what you configured so far.

                                  @stevo One thing about your config.g that looks odd to me is that the steps per mm for Z look right for a metric lead screw but looking at your machine name, I'd have thought that you would be using Acme threads ☺

                                    1600 is a lead screw 1 start 2mm lead.
                                    some people use them because it allows for 0.01mm layer height variation.

                                      I know. I was making a joke when I saw the OP's machine name. You need to have watched the cartoons to know the significance of "Acme" though.......
