      That's really cool, I missed your original post! The first tool changing delta I am aware of is from 2013 (see https://www.youtube.com/watch?v=f60YuBrHRCA -- it's actually a pancake printer as shown in https://www.youtube.com/watch?v=t3O19n_JqXU).

      We've come a long way in the mean time! Can you give some details on your locking mechanism? It seems way more involved than a bunch of magnets.

        @oliof Yeah you are right - I found these videos, too, when I started to look into tool changing Delta printers, but not many infos out there.

        About your question - yeah a little more brain juice went into the design of the locking mechanism.
        So it is basically a bayonet lock that is driven by a Bowden cable and reset by a bunch of springs

        The pieces of the bayonet that lock the tool are angled so a downward force is created by the rotation of the bayonet. It is locking onto 3 zylindrical pins that are placed 120° apart from each other so that the locking is uniformly

          Pretty cool! I hope you publish your design one day as this would be an interesting setup for three printers down my ideas to build (orthogonal tripteron, or sextupteron). But that's a couple years out optimistically speaking (-:

            Thanks that you like it! Yeah as soon as this version will be finished I'm thinking about publish the files under CC-BY-NC so that the community can use it 🙂

            BTW: I really love your unconventional tripteron design!

              The design is not mine though. That credit goes to Evan Callicoat.

                  Hey guys,

                  worked a little bit more on the printer.
                  I got the first automatic tool change (even if it needs a little more tuning), but it's a first step in the "proof of concept" direction (which I already did with the first prototyp).

                    @taconite that's a cool design. Where did you get the tapered metal parts?

                      I designed the tool so, that it utalizes standard stock material. The tapered part was done by a friend of mine on a standard lathe.

                              @taconite Hey any thoughts about preventing heat-creep after a (hot) tool is placed back on the carousel?

                                @jpomo10 of course ;). There are multiple options:

                                1. set the stand-by temperature so low, that a equilibrium is reached
                                  (+ no additional fans, - long heat up time)

                                2. one fan for each tool in parking position
                                  (+ sufficient cooling, - lot of fans with lots of noise)

                                3. one bigger fan with a fan-duct to direct the air to the heat sinks of the tools in parking position

                                For now I have no fans at all. So after the first prints I had not a lot of heat creep and no problems with jams. But I guess I will move on with option 3

                                BTW: I posted another video of the first dual color print on youtube

                                    Is the tool-changer "carriage" set up as an additional axis? How does it increment along with the Z-axis?

                                        In this small video I print with my go-to 100mm/s-profile

                                        And I just uploaded a video of the change of 4 tools

                                            @jpomo10 Nice to see that others are thinking about options aswell.

                                            To be honest these were my first attempts aswell. The first concept was magnets and the second one permanent-electromagnets after that, but after a lot of testing I decided not to use magnets.
