extruder mod d121|17
I was annoyed that printing TPU (flexible) Filament was only possible very slow and often the filament squeezed and jammed, so i wanted to change that. When i opened the barrel and tried to remove the PTFE inliner i was a bit surprised that half of it was missing (probably also causing problems when retracting - not to mention that the missing bits of teflon (PTFE) probably have worsen the print and layer adhesion). However I just turn that barrel 180° and put a larger inliner in. With the narrow end pointing to the nozzle, the heated chamber is more defined, and much more importand the filament is guided all the way from the drive. Now i could use the max extruder speed without any issues.
