Loading flexible filament into Prusa XL Nextruder
Dear all,
I have a very flexible filament (Filaflex 60A) that I'm trying to load into my Prusa XL. The problem is that I cannot get the filament into the tool.
I am already bypassing the side filament sensor and feeding the filament directly into the tool head, but the filament does not even reach the gears. I have cut it flat, I have cut it at an angle that gives it a very thin point, I'm twisting around, but no matter what I do, it seems to get stuck somewhere in the channel leading to the extruder gears. Loading stiff filaments or regular TPU is no issue at all, that works fine. It's just this very flexible filament that I find no way to load.
I'd appreciate any advice that someone may have.
Best,
Stefan.

Use a solder pen or whatever to splice some pla/petg to the tip of the tpu to help guide it. Then extrude multiple multiple times to purge all of the guide tip material from the nozzle.
