For the UMS5, the key is to not use the tensioner when running igus I180-PF filament. Here are the best suggestions that I have received: 1. Run the tensioning screw all the way loose. 2. Lift the handle that is used to put tension on the filament, so that the handle is facing downwards, but not clamped into the tensioning position (picture is attached for reference). 3. Printing it at 240°C works best. 4. Turn off retraction.

It begins right at the start. As soon as the print starts, the material is fed to make a prime blob. That is when the grinding happens and the filament will not flow out of the extruder. I have cleaned the nozzle (hot and cold pulls with Ultimaker cleaning filament) and still haven't had any luck. I have loosened the tension and pulled the handle up to release the set tension, but still keep some tension on the filament. In other words, the handle is not completely upright (meaning the filament could be pushed through with no friction). I hope that made sense.

No worries. I have used it afterwards, with no issues printing PLA. With the print core cleaning, both hot and cold. I have been able to clean it out and it was pretty clean afterwards. The filament did mirror the internals after a few pulls (meaning I got all the gunk out).

Yes. The print core works flawlessly with other materials. I cleaned the extruder with cleaning filament before inserting the I180 material. Only issue is the gear eating the material each and every time it pushes on it.

I have purchased some Igus filament (iglidur® I180-PF) and am trying to run it with my Ultimaker S5. I have attempted it several times, each with the same outcome.. grinding the filament. I have ran the tension all the way off, all the way on, and every possible place between.. to no avail.. Does anyone have experience using this filament on a S5 (or any gear-fed/bowden tube printer)?
