Hi, I have printed a small holder for a Bowden tube to print from my filament dryer outside of the enclosure, but the filament coming out of the tube is tensioned and I don’t know if it will cause problems later. Is this fine to keep or how can I fix this? This i a Ender 3 V3 SE btw.
Yes, that will cause problems. Don’t attach it to the frame. Attach it directly to the toolhead.
I’ll say that it can lead to uneven extrusion and even skipped steps on your extruder. How much, and how much that amount matters is entirely dependant on the setup and your workflow.
There are a few 3D printed solutions to keep filament tension neutral using a buffer system. It’s not a bad idea to check out some of them.
What type of a spool holder you have in the dryer? It might be a good idea to get some bearings in there to help the spool spin as freely as possible.
That should be fine, I’ve printed tens of kilograms pulling the filament around a sharp corner. As long as it’s dry, pla can handle quite a bit of abuse. And it’s unlikely to damage your printer or dryer.
In the worse case you might have some dust buildup, keep it clean
Re: dry. I’m convinced PLA doesn’t care about moisture. Watched a video of a guy that soaked a roll in a tub of water overnight, then printed off the roll with it still in the tub. Looked exactly the same as it did before the soak.
Mileage may vary of course but ever since then I’ve been leaving my PLA out and it’s never once given me trouble (the infused ones a little bit).
