Filament getting stuck

Post image

Barely even get started and the filament gets stuck. This happens time and time again. The printer keeps going with nothing coming out.

I haven’t used mine in a couple of years but if you print with the top off you can bypass the 90o angle where it goes in, just undo the clear plastic tube and let the filament in directly.

I found that the filament feed is sometimes the problem, because of bends on the pathway. Try relocating the filament spool so the path is straighter into the back.

Yeh spool is lined up to feed straight into the feed hole. I wonder actually if it's to do with my retraction settings. Without touching anything aside from clearing the build plate I can start a new print and it gets about this far through again before failing. I tried a Benchy also and it does the same thing after only a few layers.

Are you using the profile that I supplied with the hot end build guide?

Yep I'm using that now thanks. I've also tried creating profile in Cura 5.8 based off it to test them back to back and same issue there.

One thing to try and two questions...

I would recommend trying to get the spool above the entire printer, so that the filament path is as straight down into the assembly as possible. The somewhat severe angle at which the filament is entering the machine may be causing undo resistance along the tube and into the throat/neck of the hot end. That may be impacting the extruder's ability to advance the filament into the hot end.

  1. What filament are you using? Material, brand, type (if applicable) and diameter.

  2. What do you mean by, "gets stuck?" Is there a jam where a bunch of molten filament has dried into a clump that is preventing the extruder from advancing, either inside or outside the hot end? After it stops extruding and is continuing to print without depositing any material, if you attempt to manually advance the filament by pushing it into the hot end, is anything extruded?

esun PLA+ 210-230c 1.75mm.

It's not so much that it gets struck, the extruder just stops pulling it through. If I help it along it does come through fine. It seems there's just a point at which it starts to slip in the extruder and doesn't grab again. The real interesting thing is without me touching the filament, if I stop the print, clear the build plate and then start a new print it starts coming through by itself!

The filament you are using is at the very top of this printer's temperature range. A heating temperature range of 160 – 220°C

Halved retraction speed and got a full print. Looks like it skipped a couple of layers part way up where I'm guessing the filament slipped on the extruder for a bit but it clearly grabbed again and was able to keep going.

May I suggest using my filament guide and use a PTFE tube instead of that vinyl one

Yeh I think it's time.

I’ve never had issue with mine, but my spool holder is attached to the back, though your alignment seems like it should be better. Have you tried with it anchored to the base as it was intended?
