      Hi gents,
      I tried something similar 5 years ago with Delrin balls,
      Old Video
      but glueing them to a printed effector wasn't the most accurate thing.
      Now I'll try it again with resin printed ballstuds (0.03mm layer and pixelsize).
      Replacing six magnets and ballstuds is ~95grams less on the effector side.
      It was pretty hard to get a picture of the craters and layer-lines.

      I will use springs and fishing line to hold the rods in place.

        @o_lampe Do you have some picture of the setup?

        I am curious to see what you've done - I have some problem with Haydn ballstuds, the coating on the is wearing out.

          @Fred-Y I know that issue. When the airgap between magnet and ball is worn out, the POM parts must be replaced.

          Unfortunately, I haven't done the modifications yet. I also work on a new extruder design and don't want to change two major things at once.

            @Fred-Y I use a ptfe foil to lubricate ball-arm joints.

              @apak Thanks for the tip!
              I will definitively order a roll 👍

                @o_lampe yes, that's exactly the problem.
                Your project with the extruder is exiting, I remember seeing your thread a few months ago - I see a lot happened since so a lot interesting stuff to read 🙂
