      @fcwilt thanks for your tip!

      Here is what I use in the "before layer change gcode" in Prusaslicer:

      G92 E0.0                                                                    ; reset extruder position to 0
      {if layer_z == layer_height+first_layer_height}M98 P"layer_change.g"{endif} ; execute layer_change.g
      ;[layer_z]
      

      This only executes the macro on layer change from layer 1 to 2.

      Thanks.

      If for some reason in the future you would need to run code on other layer changes it would be easy using a RRF global variable to make the "first layer" test in your macro and simply have M98 P"layer_change.g" in the slicer.

      This would also have the minor benefit of keeping all of your code together in your macro.

          Will have to check with DC42 on whether this is the expected behaviour of M500.

          What should be happening is:

          • Once you save using M500 P31 then assuming you have one or more Z probes defined, a G31 line or lines will be written to config-override.g
          • If you have M501 in config.g then that G31 command will be read at boot time and the "save G31 settings with M500 automatically" flag will be set. So subsequently, sending M500 without the P31 parameter will include saving G31 settings.
          • If you delete config-override.g or you manually edit out the G31 lines from config-override.g and then reboot, M500 will no longer write the G31 settings unless you specify the P31 parameter.

            Looks like the same issue

                  @cr3d I can provide an internal build for you to test with. Would that help? Which Duet do you have?

                        Quick answer -> now it works!

                        We can use M500 / M500 P10 / M500 P31 / M500 P10:31 and nothing gets deleted 🙂

                        Thank you!
