      @taconite that's a nice tool changer!

        @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

              @taconite Thanks for the reply!

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

                Yep it is set up as U axis. I wrote a custom post-processing script for cura 😉

                  Hey guys,

                  I keep posting small videos - some are not really special but I still want to share them with you: https://youtu.be/6-CR_1vN3cE

                  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.

                        Hello guys,

                        I went a new way for the cooling of the tools without some parts of the sci fi attack hovercraft.
                        I added a fan to each tool instead. The data shows that the cooling is sufficient.

                          Hey guys,

                          so at the moment the printer is 99% finished. Just some minor modifications need to be done.

                          If there is interest in the community I will put the files on thingiverse and a BOM and some instructions on github - just let me know.

                            I'm sure there is a big interest, but the custom CNC parts are cooling down my curiosity.
                            Why not open a (kickstarter) campaign and sell the required parts?

                              Valid point but the good thing is the only custom CNC part necessary are the conical rings for the tools and those will not break the bank.

                              The sheet metal parts are not needed for the system to work. Everything else can be 3d printed or not a problem to source.

                              Currently I am working on an improved V3 which need more metal parts to be custom made, but this version should be a good option for the typical maker

                                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

                                This part is the most interesting detail to me.
                                I'm currently planning to make a tool changer for my CoreXY with a Titan extruder. I want to change the heatsink only and until now I'm on a magnetic twist & snap road. Your design looks much easier to implement, but a CoreXY can't lower the effector to release the heatsink.
                                Anyway, I'll mention you in my Biography if I steal this idea from you 😉

                                  What you could do is a C shaped bayonett so you open up the groove-mount and close it again. The C could hav a little bulk in the middle to press the groove into the correct position

                                    That's an option. I had a different idea last night:
                                    I use these two hotend pickup pins as twist&lock pins, too.
                                    The pins would be *U-*shaped and they are mounted into the heatsink-adapter. The tool changer would then connect with the pins and the guides inside the tool changer would twist the pins to unlock the hotend from the Titan housing. I have no idea how to design this twist in Fusion360. But I'll post it in my Blog

                                        Can you please explain the different functionalities? Seems you mixed different material to get different properties (stiffness, flexibility/compliance?)

                                          So of course the functionalities come with the multi-material print

                                          1. reduced friction and therefor wear
                                          2. increased strength/stiffness
                                          3. flexible material for compliance/dampening of torque peaks
                                          4. Sensor element for the detection of wear
