  1. Hello everybody, I'm facing the same problem of a persisting "difference between print cores exceeds realistic values". I've tried all the suggestions I read in this thread but it still remains. What actually happens is what you describe at the end of paragraph 1): The nozzle never reaches the glass but thinks it did. Any help is greatly appreciated! Edit: I have a Ultimaker S5 printer which runs on the latest stable firmware version.
  2. Hey @MariMakes, thanks for your tips, I tried them but could not yield better results unfortunately. Something else I now noticed, which might be a source of error, is that the extruder is forming a loop of material instead of a straight line. This is visible when I'm actually trying to print my design but it's better even better visible in the step of material loading when the material is extruding out of the nozzle to make sure to push out the formerly used material. This was the case for my self-made PCL (see-thru) but also for commercially-bought ABS (green), which I also tried. Do you have an idea where this problem comes from and possibly also on how to solve it?
  3. Hello @herzchirurgie001 I'm facing similar problems, have you managed to solve the problem? I'm simply trying to print a PCL cube with my UMS5 but just a big chunk of PCL on the nozzle is all I get. How did you make your PCL stick to the (glass) surface? Or did you use a different material for the bed?
  4. Hello everybody! I'm trying to print something (a simple cube) out of PCL (Polycaprolactone, Mw=80k) and I'm using an Ultimaker S5 to do so. Unfortunately, the print will not stick to the Glass bed but instead accumulates around the nozzle. Do you have any tips for me on how to print PCL? Some specs: Nozzle: AA0.4 130°C printing temperature Bed: Glass, 40°C with glue at the spot where the print should be Speed: 20 mm/s Fan Speed: 100% One further problem might be that I have to make the PCL filament myself, so the thickness of the filament is only approximately 2.85 and maybe not exactly 2.85mm. What I've already tried was to do manual leveling of the bed, because I thought that maybe there was a problem with the nozzle being too far away from the bed. Still no better result. Any help is greatly appreciated!
