          Hey Guys,

          I uploaded some videos of the first prints here.
          Furthermore I added a video of a manual tool change

            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?

                                      @JoergS5 Thank you
                                      @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?
