  1. Hello, I tried to print with nylon last week and after 5-6 layers of printing it stopped and displayed ER31 on my Ultimaker S5.(I use the Ultimaker profile for the Black Nylon in Cura) It has done this 3 times now and only with nylon. I think the error is with the print core but i don't know how to fix this. Any suggestions?
  2. So I tried pulling on the filament with around 10 pounds of force when we were moving it in the material menu and it kept moving. Also we performed the hot and cold pulls until we were satisfied the nozzle was clean and clear. The PLA was extruding fine out of the print head when manually pushing. We then tried putting our spare AA 0.8 print head in which is very rarely used by us and has no blockages in it. When this print head was in we tried to move the PLA with the move function of the Ultimaker and the filament was still being ground away. This leads us to believe this is an issue with the feeders, not just feeder 1 but feeder 2 also. And the retractions can't be a problem as I'm not even able to start a print! I found an old thread of someone who had the same problem as me and I have also tried the solutions given in this thread too.
  3. Hi all, I seem to be having some trouble with my feeder in my Ultimaker S5. What seems to have happened is that there was a blockage in my AA 0.4 print head that stopped this blue Ultimaker PLA from extruding. This in turn must have started this grinding problem in feeder one of the printer as the feeder tried to push through filament and just ground it away instead. I have cleared the blockage in the print head now but every time i try to extrude the PLA using the feeder controls the PLA extrudes a little bit absolutely fine for a small amount as seen in picture 4 but then the feeder starts to grind away at the filament again until it is stuck. I have tried increasing the feeder tension and decreasing it but neither of these have worked as the filament get ground away after a small amount has extruded again. Last week the printer was fine and there were no feeder issues so i don't know what has happened for the feeder to fail every time. How do i stop this from happening?
  4. Yeah I do and i just solved my own problem as well. It turns out I was being dumb and the USB I was using was messing up the files for some reason, which was weird as I have been using this USB fine for a while and always eject it. Thank you though for replying and taking the time out to help me.
  5. Hello everyone, This morning I tried to start a print after adding a custom high temperature PVA. However when I was going to select the print from my USB in the printer it had a red triangle and said "something is wrong with this file". First i reverted the material to normal Ultimaker PVA but it still had this problem. Then I reset my computer and tried to set the print in Cura again but this didn't work. Then I used a completely different computer and it still had this problem with the red triangle. I also tried to print something completely different to see if it was the actual .stl file that was broken but this also didn't work. What else can i do to try and fix this problem?
