      Link here for flying extruder version also

      using the pcb supplied guarantees perfect spacing

        This is what I used, I will try the stl file you send me, probebly the safest option to use the pcb's. Your second link goes to a tray, not sure what to do with that 😉

          Make sure that the spacing between each pair of towers is the same at the top, the bottom, and half way between top and bottom from duets website

          The spacing between the bearings at the top of a pair of rods must be exactly the same as the spacing between the bearings at the bottom

            get the linked version with the flying extruder mounting holes easier to mount the extruder

                One thing I did change on my bed was the standoffs under it the blue discs if you take 2 off and measure them mine were way way off in size each to each I replaced them with springs but that was after getting my setup sorted

                    Hello, I tried printing the parts yesterday (small parts usually work after some fiddling) and halfway a belt snapt, thats what you get after to much tensioning for more precision... But anyway, I changed all the belts to new ones with a metal core which I had as spare, tensioned the same and printed the small parts again, which went easy somehow. So I tried to print the big part to be sure. Perfect first layer without a mesh, just after a quick delta calibration.
                    No idea what was wrong with the other belts, could not find any problems on them and the were installed correcly and tried several amounts of tension over the last year.
                    I will install the new mounts for the arms anyway to remove the 0.5mm, but they do not couse the first layer issue.
                    Thanks a lot for al the help, It was a hardware foult afterall, altough I am still not sure what was wrong with them.
                    The support on the forum is great, really thanks a lot.
                    Should I close the thread somehow to show it is fixed?

                      thats a big no no. steel belts do not like sharp turns like you have in a delta. they will break and cause problems.

                      here are some good belts

                        Interesting, I had to replace a belt on the original predator and I thing it has more then a 1000 hours with a metal belt in 1 tower... No problems
