    Should I finish building my 350-400mm diameter delta?

      My delta with a 330m diameter bed (of which about 300mm is printable without the effector hitting the towers) is working really well since I installed linear rails, Haydn's magnetic arms, and the PCB effector and carriages. The only change I would want to make for a larger print diameter is to ask Haydn to use thicker carbon fibre tubes for the longer arms.

        Thinking of doing the same, so I'll be watching. It is funny watching these massive printers printing Benchys. I really wonder how many get put to their full use.

        hmmm i wonder who holds the record for workds largest benchy

            One thing I can say is that you should tripple check the length of the linear rails, my friendly chinese vendor delivered great running rails to me, but it seems they were cut in two batches and one of the rails was 2mm shorter than the other two, not something you'd expect but it seems this can happen…

              Now that sounds like a challenge!

                I didn't see a spec on the website. Are Haydn's arms 6mm x 4mm?

                  They are 6mm o.d.

                    Would the thickness be for accuracy or running the printer at higher speeds? What arms length did you use for yours?

                    What I will probably do is wait for the PCB effector and carriages to be released and use those in the build with some longer Haydn's arms.

                      The extra thickness is because I'm not convinced that 6mm CF tube would be stiff enough for longer arms. The arms on my delta are 360mm.

                        I was inspired by d42 to get into building a large delta. … I used smoothieware as at the time duet was in transition from 0.8 to ethernet/wifi (over a year ago). If I had to do it again, I'd go with duet -- I had a lot of trouble with the Azteeg board, eventually switched to authentic smoothieboard.
