    Hi everybody

    I'm using E3D Tool Changer.

    When a tool is not used, the temperature respects Standby configuration.

    For exemple active 220°C, 200°C Standby.

    I want that when a tool is selected, the heat up comes while tool is still parked, not after it has been took and moved to bed.

    So I tried playing with tpre.g file

    I tried with M116 without success.

    ;Unlock Coupler
    M98 P/macros/Coupler - Unlock
    ;Move to location
    G1 X212.9 Y200 F50000
    ;Move in
    G1 X212.9 Y230 F50000
    ;Collect
    G1 X212.9 Y242.5 F2500
    ;Close Coupler
    M98 P/macros/Coupler - Lock
    M116 P2; heat up
    ;WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
    ;if you are using non-standard length hotends ensure the bed is lowered enough BEFORE undocking the tool!
    G91
    G1 Z10 F1000
    G90
    ;Move Out
    G1 X212.9 Y150 F4000

    It always moves to the bed and then heat up...

    Thanks !

      Your M116 should be in TPost

      https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Tool_change_files

      You probably need to move your "move out" code there as well.

          So I moved :

          ;Move Out
          G1 X212.9 Y150 F4000

          from tpre to tpost, after M116

          So it works as it heats up before move out.

          But when it moves out there a little x movement where it should not be...

          I think it is a relative/absolute issue but I don't find the way to solve it...

          Thanks !

            What firmware version are you using? M115 to find out.

                I've edited your post title to match your current issue with X movement on tool pickup.

                  That's exactly the issue 😉

                  I partially solved the issue by replacing :

                  G1 X212.9 Y150 F4000

                  to

                  G1 Y150 F4000

                  but even if there was X212.9 it should not move on X at all.

                  Best regards

                    @sylvain do you have a G10 offset which is moved when you change the tool?

                      In fact I have in config.g:

                      G10 P2 X-9.0 Y39.5 Z-4.8

                      And I believe that the x movement is 9mm (when I look on web dashboard, I calculate a 9mm x movement)
