    If you are up for suggestions. I would swap filaments at the layer after the base is finished and switch colors so that the logo will pop against the base color.

      That’s what I currently try (I am not OP) and it does not works. The slicers use one magic Gcode command (M600) that does all the filament change movements and interactions.

      My shitty printer (Weedo Tina2) does not recognize this command (I have found the documentation).

      A printer at my fablab (artillery X2) just ignores it.

      What do you use to make midprint filament change?

        You can also just pause it and change filament manually.

        Just remember to push through some of the filament until the color comming out is right.

          You mean going trough the menu ? I have never used this feature. When you “pause” the print, does the printer head goed to the origin (to be able to push the filament" ? I can imagine that it depends of the printer…

            I mean inserting the pause gcode command in the slicer. The idea is that this command is very basic, so every printer supports it, as opposed to a filament change command.

            I used Cura and IIRC you could add “move away from the print and move back when unpaused” commands.

            I haven’t 3d printed for far too long, so my memory is very blurry. You might be better off looking for a Youtube video or googling for a tutorial, but it wasn’t rocket science once someone on the internet explained it to me.

            Edit: maybe try searching for something like “3d printer filament change pause”

              Thanks ! I have tried this in Cura (“pause at height” script instead of “change filament”). You can select the pause gcode instruction. Most of them does not works… but one of it works!! My first two-color print!!

              I still have to manage how to purge without making a mess on the bed.

                No problem! I’m glad you got it working!

                I would just pull the first filament away from the bed and the rest usually follows along and you get a little birds nest.

        You can insert any custom GCode at any layer, at least with PrusaSlicer. So check what your printer supports for changing filament and try that.

          OK… looks like I could play with M226.
          M226 waits until a pin’s value changes - you have to know the numer of the pin.
          M43 allows you to display the pin’s value. I may find a pin matching with the user’s button.

          These two exotic instructions are implemented in my shitty printer (from the documentation). I have to try it.
