PSA: Star-shaped Bowden tubes are terrible for flexible filaments. Instead of reducing friction, they can increase it—because the filament gets pushed into the star “corners” under tension.

I've got A LOT of failed prints with my #creality #ender5 #3Dprinter. It #clogs very easily. I tought the #filament was wet, but a couple of hours ago it #clogged very badly and I had to completely #disassemble the #extruder, #hotend and even cut a little piece of #bowdentube... before doing all this work I looked at a video explaining how to do it and...

...I SAW it. The #fan. The f...ing extruder fan in the video was running from the moment the #printer was switched on. I have never seen mine running, I always tought it was temperature controlled or something... It was just #jammed 🤦‍♂️ Unfortunately the plastic was very tired by the heat, so a blade broke instantly while cleaning it.

It seems I have to wait for a #replacement part, but at least I found the problem. That's why the printer was SO #temperamental!
