      @taconite said in D-PATCH:

      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

            Hey guys,

            just a quick update. Here you can see a printed spur-gear with different functionalities.

              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

                  @taconite thank you for explaining! Do you use some of those BF350 as sensor or something different?

                              @HebigT slow and steady 😄

                              @PCR Sure if there is demand I will put all the files plus BOM on Github (or similar). The one you see is lets say the "maker" version where you need close to no custom parts.

                              At the moment I work on another version with some improvements (which can be easily implemented in the maker version)

                                @taconite that would be great! I really Love the Idea of a Delta toolchanger!

                                  Just saw that you started to sell the D-Patch! Really nice! When is ETA for the "Maker" Edition? Or are you selling the custom parts too? Greetings from someone who was born in bavaria too 😉
