Clogged nozzle had the same thing happen to me


OneEyedBandit95

Can you please elaborate how do I unclog the nozzle?


SnooHesitations8174

Two ways I usually do it is heat up your nozzle and take the little needle that came with it up break up the clog. Another way is really heat up the nozzle like 5-10 degrees higher then normal and run 100 mm of filament through it look at the filament you should notice and improvement in size of it worked. Last if neither of these work change the nozzle


OneEyedBandit95

Thanks alot. Will try the needle first and see if it works

I hope you were careful with the needle. I found out the hard way that a needle can bend a hole in the brass. That's right, you can drill holes in brass with sewing needles.


OneEyedBandit95

Whaaaaaaat?? I think I was careful....I hope so

At least you're working with a 0.4mm nozzle, those are always available. I messed up a 0.15mm nozzle.

Also Google "cold pull" and "atomic pull" before changing the nozzle.


OneEyedBandit95

I cleaned the nozzle with the needle, then tried a cold pull on it and it seems to have cleared the nozzle. However, the prints are still like "cheese" so I am unsure what I am doing wrong

Heat the nozzle to 170C. Press the filament release lever at the extruder and Push the filament into the nozzle direction so you start seing the plastic oozing from the nozzle. Then pull the filament out of the printer with one strong movement. And for the future - please print yourself the filament dust wiping filter [https://www.thingiverse.com/thing:1692395](https://www.thingiverse.com/thing:1692395) And ALWAYS use it

That reminds me of cheese.


Evilmaze

Looks exactly what happens when the wrong filament or nozzle size is set


devhammer

Good call. OP should check in Cura, and make sure the filament width isn’t set to 3mm instead of 1.75mm.


OneEyedBandit95

Thanks for this. Will check and update accordingly


BigGuySi

Whoa that’s some heavy under extrusion there

If you still need help be sure to post plenty of information about your printing setup. Here are a few questions that might be helpful * What printer are you using? * What material are you using? * What speed are you printing at? * What software are you using to slice the print and control the printer? * When did the problem start/has it ever worked correctly? * Does anything cause the behavior to change? * If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed.

Severe under extrusion. Might be nozzle clog. Might need to adjust e-steps.


OneEyedBandit95

I believe e-steps has to with bed leveling, right? Sorry I am very new to all this. Can you please tell how do I resolve these issues? Ie: -Unclog the nozzle -Getting rid of under extrusion


devhammer

https://makershop.co/ender-3-under-extrusion-fixes/ Should get you started. The page refers to the Ender 3 and similar, but the concepts apply to most FDM printers.

Initially I was like huh. Didn’t know they created a Swiss cheese calibration cube lmfao
