  1. I think I will loosen the screw, move the axle with the other pulley to its stop, then move the loose pulley to its stop (distance tube) and the tighten the screw - done!
  2. Hi, my ULTIMAKER 2+ has the problem that one of the axles (only on one side) moves back and forth by about 2mm when the slide that moves on that axle is moving fast (s. picture). I suppose (close to being sure) that one of the pulleys has moved, although there is no visible slip during printing and the prints are good!? Thanks for the answers in advance!
  3. Maybe I now found the reason for the different print results since I'm using Cura2.3! I was using the new Cura version without updating to the new firmware version. Now after installation of the new firmware the head movement seems to be different now (especially the head movement at the beginning, when the printer moves from the top corner to the print position, is much faster now). Now the prints seem to look more accurate than before!
  4. No, I think the problem with my printer is different, but I now printed a different text with a font that has slightly less fine structures and that was printed well. Also the infill was more dense than with the previous text, so maybe the problems might have more to do with the printed structures/Cura than the printer!? I now will try the text with a higher nozzle and buildplate temp and play a little with other settings too! Anyway I ordered a new nozzle, too! Thanks for the help!
  5. The thing is that before it worked as good as any other colour I have used so far (s. e. g.: and this was fast print with support) What do you mean with "squish"? Regarding PVA I tried to use the glue that came with the printer, but that didn't help a bit! So I will order a new nozzle and try again! THANKS!
  6. After printing several fine structured, low height (0,6 - 1mm) texts with no problems, I'm now (after 97 printing hours with 53m printed) running into problems. I attached a (multi-picture-)picture where you can see printed text. Pics 1 and 2 show the current prints which mostly are ripped of by the print-head either because the Material doesn't stick properly on the bead and is ripped of already when printing the first layer, or because of parts that bend up after the printer has printed a few layers. Pic 3 shows a text that I printed before (along with many others) without any issues. It happened also before that something has been ripped of, but rarely and now it is always ripped of. When I'm using 1mm Brim it prints o.k., but Brim is not acceptable for decorative text. As I'm not printing decorative stuff very often (only sometimes for a colleague), but mostly functional parts (which still print without any/relevant issues) I'm not extremely worried by now, but maybe the problem increases and I would like to find out the reason. I already recalibrated the build plate (several times with different distances), cleaned it accurately and did the "Atomic - Method". Also the marks on the filament behind the feeder do not reveal feeding issues (as far as I can say). I also tried it with a different Material (but from the same supplier: "Innofill") with the same result. At the beginning of the print when the Material is printed in the air, the flow is straight and looks good. Despite that I still have the feeling that there is a little underextrusion during the print! Could it be the coupler or more likely the nozzle (or something else)? I'm using a 0,4 nozzle with a "Layer Height" of 0,06 and a "Wall thickness" of 0.4. "Print Speed" and "Infill Speed" is set to 30, "Travel Speed" is set to 120 and "Initial layer speed" is set to 20. "Retraction" is enabled. Most or even all (I don't remember exactly) of the properly printed text was printed with Cura V2.2.x, but now I'm using Cura2.3.1. Thanks for the help in advance!
