Hello I usually print with PLA tough or normal PLA and use PVA as support material. Now I decided to try flexible material, so I chose Polymakers PolyFlex. So my problem is that after 10 minutes of printing the print stops and error message is that "material appears to be empty". And when I release the motor the filament is highly tensed in the bowden tube. So it's supplying more of the filament that is actually coming out of the nozzle. And when the tension is high enough the motor is not able to push more filament in, so it thinks the material is empty. Also the part walls dont seem to connect and they are seperated from eachother. I'm using Ultimaker S5, the default settings for TPU material, AA 0.4 extruder and the filament is brand new from the vacuum bag. I've tried to adjust couple of settings: layer height, printing temp, material flow %, printing speed and retraction. I think the problem is that the filament motor is so far away from the extruder so it gets tangled in the bowden tube or something. So the question is that: Is it even possible to print TPU with Ultimaker S5 and what am I doing wrong?
