Printer has clogged three times in a row | 3D Printing | Page 1

The first time it happened I let the print go on for hours without noticing (it doesn't extrude just does the movements). When I noticed, I got the PTFE tube out and had to cut around 1cm to pull the clogged piece out. The second time it clogged, it looked like a piece of filament fell in the area where it's supposed to go out. After some pushing and pulling I got it to extrude properly. Now it's the third time and its clogged again.

AI Help

It seems like you are experiencing recurring clogs in your 3D printer's extruder. Here are a few troubleshooting steps you can try:

Check the filament: Make sure the filament you are using is of good quality and properly stored. Moisture or contaminants in the filament can cause clogs. Try using a fresh roll of filament and see if the issue persists.
Clear the nozzle: Heat up the extruder to the recommended temperature and carefully remove the nozzle. Clean it using a nozzle cleaning tool or a thin needle to remove any obstructions or leftover debris.
Check the PTFE tube: Inspect the PTFE (Teflon) tube for any damage or deformities. Replace it if necessary, as a damaged or improperly installed tube can cause filament blockages.
Adjust the extruder tension: If the filament is not properly gripping or is slipping in the extruder, you may need to adjust the tension. Consult your printer's manual or manufacturer's guidelines to adjust the tension correctly.

Also the first time I got some water in the tube but I didn't feel any moisture when blowing through it

My ender 5 was also experiencing repeated clogs.. became extremely frustrating.

I tried everything: Cold pulls, cleaning nozzle with needle, replacing nozzle, replacing boden tube, adjusting extrusion tension.

The problem was the filament I was using was not precise diameter. It was that multicolored stuff.

What worked best for me was after each clog I'd just cold pull and replace the nozzle. Not worth my time to try 6 different things over and over.

You can tell if there is a partial clog by heating up hot end and watching filament ooze out.. It should go straight down, if it curls to the side there is a partial clog.

I cut it off and threw it somewhere

#

Also potentially some heat creep? From the fact it's getting stuck in the tube?

But it's just a glob at the end

What would cause that

lean phoenix Oct 27, 2023, 5:03 PM

#

Insufficient hotend cooling

#

Which, on the stock E3 hotend, is fairly expected.

still robin Oct 27, 2023, 5:03 PM

#

What would cause that

#

Oh

lean phoenix Oct 27, 2023, 5:04 PM

#

The heatsink itself isn't exactly the greatest design and needs a reasonably decent fan. Even a failing/weak fan can be a problem there

#

In this case it's the one that cools the upper red section - which keeps the tube cool so the filament only melts where it should

#

Still, I'd check for gap first as any leaking there would cause similar symptoms

#

Does this look bad?

lean phoenix Oct 27, 2023, 5:07 PM

#

That does not seem particularly flat.

#

It needs to have a nice, clean cut to give as much surface area at the bottom for the nozzle to seal against

still robin Oct 27, 2023, 5:07 PM

#

How do I make it flat

lean phoenix Oct 27, 2023, 5:07 PM

#

Using a proper cutter or being very careful to cut it straight down by hand.

#

You need to use a very sharp blade.

#

Crushing the tube will cause a weird cut which the nozzle can't seal against.

#

No, those are diagonal cutters

#

They will also crush the tube

#

#

Talking about something like that.

I don't got no guillotine 😭

lean phoenix Oct 27, 2023, 5:10 PM

#

Yep, hence: very sharp knife. A box cutter even

#

The only thing that matters is that you cut it straight down with the cleanest cut possible

still robin Oct 27, 2023, 5:10 PM

#

Wouldn't it still crush it tho?

lean phoenix Oct 27, 2023, 5:10 PM

#

still robin Wouldn't it still crush it tho?

If it's sharp enough it won't crush it

#

No different than a sharp kitchen knife not crushing a tomato

#

Another important thing when sealing a PTFE lined hotend is to screw the nozzle in most of the way, then back it off about a quarter turn. Press the tube in firmly, heat to 220C, then tighten the nozzle (WITHOUT any filament).

Can you simplify

lean phoenix Oct 27, 2023, 5:13 PM

#

That's about as simple as it gets

#

Put the nozzle all the way in, back it off a little, put the tube in and then heat it. Then tighten it.

#

Don't need much torque, remember we're just squishing the top of the nozzle against the tube a little bit

still robin Oct 27, 2023, 5:17 PM

Wait I have a maybe brilliant maybe stupid idea

#

It doesn't matter how flat the side where the filament goes in is right?

Correct

still robin Oct 27, 2023, 5:18 PM

Ok so I could just flip it

Makes it easier to insert the filament initially but otherwise no

I should cool it down before unscrewing the nozzle right?

#

Also how do I unscrew the nozzle? Just turn it around?

lean phoenix Oct 27, 2023, 5:21 PM

#

still robin I should cool it down before unscrewing the nozzle right?

Nope! While it is hot, 200-210C. If you have a pair of wide mouth pliers (think ones for pipes) that you can safely hold the block with, use them. Then use a wrench or ratchet with appropriate sized socket and turn it.

#

It's upside down so remember - if the wrench handle is facing the FRONT of the printer, move it to the LEFT of the printer (counter clockwise facing the bottom of the block).

#

If the wrench handle is facing the BACK of the printer, move it to the RIGHT of the printer.

#

Thanks to thermal expansion if you try to do this cold you're likely to snap the nozzle in the aluminum block

There was filament around the nozzle
