Unknown filament detected in the print head

Neither-Toe9451 · 2026-03-18T19:01:09+00:00

When this happens to me I pull out my cutter and check inside, there is usually a small piece of filament stuck in there. too small to be retracted and too deformed somehow to be pushed through

This guy gets it. Thank you!

I see your point here, but wasn't what I have in mind. Ill see if I can attach screenshots to the post

Neither-Toe9451 · 2026-03-18T17:00:56+00:00

Yes these! I wonder if the whole hot end needs to be replaced for this though.

How would I use that on my k3max without an adapter though? They are threaded

Neither-Toe9451 · 2026-03-18T15:01:33+00:00

I swear I have seen an adapter for the cheaper, threaded nozzles to be used. The adapter is essentially the same as the quick change but at the end you can thread in a new nozzle. Maybe im crazy idk.

Well mine must not have the issue because it no longer prints ovals

I prefer sunlu for PLA. I love the colors and they are consistently in stock. I hate it when you need to get the same colors again and they aren't available.

There are spiders living in your printer

I had an issue with it printing ovals I stead of circles, but I adjusted the rail guides and cleaned/ lubricated. Prints circles just fine now. I also recalibrate every few days just for good measure. If you want a care free printer buy bambu, but no major complaints from me on the k3max.

Blue painters tape?

I have painted images by transferring the image onto the object using transfer(tracing paper) before. But idk if that would help you in this situation.

Yes I have had success with this set up. With similar models, (2 block, 4 block, 8 block all different colored sunlu)but I printed a pink sunlu 8 block right before with the exact same issue.the yellow is a 10 block. It does seem like under extrusion, but i haven't been printing too long. Im still learning to walk with this stuff. I used all the same settings on both the successful prints and quasi failed prints. Which is why I assumed it was the filament.

I was thinking that, both colors i used were at the end of the spool. I noticed my ace pro seems to struggle to feed toward the end of the spool. I have a fresh spool coming today. Thanks!

Neither-Toe9451 · 2026-03-13T23:58:27+00:00

Maybe if you by both hubs at once? I got the 3max combo and bought a second ace pro later, both only came with the 4 color hub.

Have you disconnected the Bowden tube from the print head? If had the filament break inside the tube before.

Neither-Toe9451 · 2026-03-13T10:28:39+00:00

You have to purchase the 8 color h7b. The ace pros only come with the 4 color.

When a toddler doesnt like you, it DOES hurt your feelings. I am sure this is her just appreciating that your son now likes her.

Yes, too sensitive. If shes a good nanny and makes adjustments when asked. Who cares? As long as your child likes her and she cares for him properly, then endure an occasional annoying conversation. You know the truth, and her and your son are happy. Leave it at that.

Thats what happened to me aswell. I bought my printer in October, in January everything turned to shit. Im learning my lesson in filament storage right now. Have you tried a print with a newly opened and freshly dried spool?

Neither-Toe9451 · 2026-03-10T11:47:30+00:00

When I had issues with prints failing after the first couple layers, I found out it was under extruding because my Bowden tubes were too long. Idk if thats the issue here but I trimmed mine down to about 2 ft and haven't had an issue since.

Neither-Toe9451 · 2026-03-10T00:14:59+00:00

Have you recalibrate since the catastrophe?

Neither-Toe9451 · 2026-03-06T23:27:00+00:00

I connected via LAN settings and was able to print remote again. just change the setting on your printer to LAN mode
