This past weekend I had a #3dprinting jam bad enough it was easier to replace the whole bowden tube. After a print or two I started getting equally bad jams with the new tube! The clue was noticing resistance just pushing filament through the bowden tube. A drop of olive oil on the foam in my dust filter provided enough lubrication and now prints are silky smooth!
Since I switched to dry stored filament in a box and enclosed my printer I never had any jams anymore.
Just my 2 filaments.
@raise-project Thanks for the tips! Yes that was the cause of the initial jam (this room gets somewhat dusty) and it took quite a bit of work to clean that out.
It was only after cleaning it out well and having a successful print or two that this happened with a freshly-opened spool, even after cleaning, and after scratching my head noticed the resistance in the new bowden tube.
I should really get an enclosure for this ender 5, but that would take up a lot of space!
@raise-project Yes the initial jam that started it all happened about 24 hours into a print!
A quick list for completeness:
- Slicer settings, anything that demands too much space and doesnt release pressure on nozzle.
- Metal heatbreak without coating
- Non dry and dust free stored filament
- Filament contamination while printing
Jammed nozzles and failed long time prints are just the worst. Lost so many time with that. Essentially the reason why I did all the precautions that could possibly interfere :D
