[Under Extrusion Help]

I've asked this before and have got no useful help. How do I fix under extrusion? I've tried every method that the troubleshooting guide has to offer, and I've replaced all parts of my hot end. What is my printer's problem? I print PLA at 210 degrees on Ultimaker 2.

[Ultimaker 2 Feeder Insert Chip question]

Hi Patric M,

You'll have to turn it anticlockwise in order to tighten, made the same thing myself first time..

Try to add force directly helping feeding, if it helps add some more force. Adjust to mark two or around, will depend of the softness of you filament. Do you use PLA?

A little more info about the setup, nozzle size etc. will help here.

Good luck.

Thanks.

Torgeir.

 

It's a 0.4mm nozzle and sorry about the mislead, but I was actually turning it anticlockwise to try and tighten it, but it still wouldn't budge.

[Ultimaker 2 Feeder Insert Chip question]

I've tried many methods for fixing clogs and under-extrusion, most to no avail. One thing that I read is that changing the tension of the feeder on the filament will help stop any slipping of the filament. I tried to insert a hex key into the top hole on the feeder and turn it clockwise so the white insert clip would go to the middle instead of being at the top like I've had it ever since I got my printer. I could not get that white insert chip to budge, and any attempt to turn the screw to increase the tension would stop the screw from turning entirely and I nearly stripped it. What am I doing wrong here?

Also, like I previously said, I've tried lots of methods for solving under-extrusion and clogging; The atomic method, replacing the coupler, temperature changes, but nothing solves the problem for longer than a few weeks. Is there something I'm missing here?

[Every layer after the first is under-extruded]

try a print with the Infill-Top-Outer-Inner, set to zero. This way all the speeds are the same and will print more even. These settings will get the same value as the print speed.

 

No difference. The print continues to be extremely thin and my printer keeps clicking and skipping.

[Every layer after the first is under-extruded]

can you take a look at your speed settings:

first - expert - full settings

second - advanced - what are your speed settings?

 

Travel Speed - 150mm/s

Bottom Layer Speed - 20mm/s

Infill Speed - 80mm/s

Top/Bottom Speed - 15mm/s

Outer Shell Speed - 30mm/s

Inner Shell Speed - 60mm/s

I assume you have done some Atomic cleans? Can you see through the hole in the nozzle after a clean? Just wondering if you have a large bit of junk floating around somewhere.

 

I've done several atomic cleans and the nozzle seems to be as clear as it will ever be.

I took some pictures to better illustrate the issues I'm having.

I would look at your PTFE coupler if it has never been changed.

Good article on it Here

hot to change it Here

 

I checked the PTFE coupler and there are no ridges inside and there is no friction when I pull material through.

[Every layer after the first is under-extruded]

I'm guessing that your PTFE coupler is deformed.

Have you done atomic pulls?

 

I've done quite a few of them, but the issue persists.

Can you post some of your setting so we can see what temps and speeds you are using?

Also what printer are you using? This can be added to your profile so we can see straight away.

What material are you using?

 

Default settings and speed, 210C, Ultimaker 2, PLA

[Every layer after the first is under-extruded]

I've had my printer for a while now and have had this problem a few times before, but it's really becoming a pain and screws up almost every print now.

The first layer goes down beautifully. Nice and flat, not too thin or thick. After that is where all the problems start. As soon as the second layer starts, it comes out thin and almost seems under-extruded. If I stop the print and restart, no clogging seems to have occurred as the first layer of the new print turns out great again. If I let the print continue in its under-extruded form, the print eventually becomes bumpy and causes the buildplate to rumble like crazy whenever the nozzle hits a bad spot.

Another thing I've noticed is that occasionally the nozzle will get clogged and then unclogged within 3 seconds. I've tried most every method of clearing the nozzle, but the problem persists.

What can I do to solve each problem, or will one fix correct both of these issues?

[Brown Gunk coming out of nozzle]

I bought my Ultimaker 2 about a month ago, and it's slowly turning into the worst purchase I've ever made. Ultimaker support is zero help. Recently, after printing for about 2 minutes each time I try to print, the PLA material stops extruding for about 10 seconds, and when it starts to extrude again, a brown, liquidy, burnt looking material explodes from the nozzle and wrecks the print every time. I'm using default PLA settings with the nozzle temperature at 230. I even bought a new nozzle and that didn't fix the problem. Can someone please help me? Ultimaker support definitely won't help me.
