      @campeancalin said in trouble with homing the x and y axes on a core xy printer.:

      G91 /G1 H2 X10 F3000"

      if this moves only in the X direction, then you do not have a corexy machine

      and decided to go further with the attempt to home the xy gantry to no avail

      what do you mean by that? there was no movement?
      the homing code does the same thing as your manual move in the first command.

      please post the output of m122

        In you config.g file you have this:

        G31 P500 X10 Y10 Z3.5 ; set Z probe trigger value, offset and trigger height

        As I recall for a BLTouch P500 should be P25

        And are you sure those X10 and Y10 offset values are correct?

        I designed my own hotend mount and the closest I could position the BLTouch was X0 Y25.


        Also for testing you can use M564 to allow using the DWC jog buttons before homing as been done.

        The possible parameters to M564 are H and/or S (see below):

        H1 = forbid movement of axes that have not been homed, H0 = allow movement of axes that have not been homed

        S1 = limit movement within axis boundaries, S0 = allow movement outside boundaries

        So issuing M564 H0 would allow using the jog buttons, M564 H1 would restore things to normal.

              ok, I might have confused it with the config tool version.

                @fcwilt do these commands work if the version of the firmware is 2.03?

                      the pin configuration syntax only works in rrf3
                      M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
                      M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop

                        Yes they do.


                        But a set of files generated for v3 firmware will not work with v2 firmware without some changes.

                        I would go ahead and update the firmware to v3.

                        First update using Duet2and3Firmware-3.0.zip.

                        When asked allow it to update.

                        Then update using Duet2and3Firmware-3.1.1.zip

                        When asked allow it to update.

                        You can upload each ZIP file on the System page.

                          Once you update to 3.1.1 your current config has a better chance of working.

                          You should probably redo the motor direction tests for corexy after you update.

                              Since you're starting from scratch it doesn't much matter, but here are the details.

                                Hello guys,
                                Thank you again for the heads up regarding the differencies between the machine config and the firmware that was on the board.
                                Today I went on and upgraded the firmware on the board, and reuploaded the machine config. At a first glance, the xy gantry seems to move in the right direction ; I still cant perform the homing on them. I also moved the z axis, on which I have 2 in series motors ( ZA and ZB are being used to control them), and while the z axis is performing the required movement , the E0 extruder motor is also moving.
                                Bellow you can see the M122 report:

                                  @campeancalin said in trouble with homing the x and y axes on a core xy printer.:

                                  which I have 2 in series motors ( ZA and ZB are being used to control them),

                                  this does not match your config
                                  M584 X1 Y0 Z2:3 E4:5 ; set drive mapping; INIT:X=0; Y=1; Z2;E3:4

                                  Za and Zb are both driver 2
