Creality K1C not extruding

[pliant pond]

There could be many possible causes. I’ve encountered similar issues occasionally as well.
But the most likely reason is that the filament isn’t properly gripping inside the extruder.

Try loosening the top latch and reloading the filament again — that might help.

i’ve done that multiple times unfortunately nothing happening

it only extrudes if i force the filament through

[pliant pond]

Are the gears on your extruder running?

[solar thicket]

i’m not completley sure

i’ll have to check

[solar thicket]

i’ve checked and they seem to be working normally

except nothing comes out

[pliant pond]

Do you have try to unlock the extruder, and just make sure you filament can push by you hand, just give it a little bit strength when you use the feeding steps by the machine

[solar thicket]

it extrudes if i push it with my hand yes

but it doesn’t extrude by itself

[pliant pond]

Alternatively, you can remove the extruder and check the machine's feeding steps to see if the gears are jammed with material, or heat the nozzle and manually push the material in. These two methods can respectively check whether the problem is with the extruder or the nozzle.

[pliant pond]

Then you need to disassemble the extruder and inspect both sides.

[solar thicket]

i’ve done that, nothing visibly wrong

i’ve also checked the gears there doesn’t seem to be any material stuck in them

[pliant pond]

Even if you disassemble the extruder and manually feed the material into the heated nozzle, no material comes out?

[solar thicket]

if i push the filament through it does come out

[pliant pond]

Okay, it seems we're having the same problem. My conclusion is that the extruder gear set has reached the end of its lifespan, resulting in insufficient force to clamp the material for extrusion. The answers I found online all suggest that this type of extruder, the K1 series, experiences this issue.

[solar thicket]

and is there a fix?

[pliant pond]

I'm not sure if replacing the extruder gears with an all-metal version would be effective now that this has already happened, but when I encountered this situation before, I simply ordered a new extruder.

[pliant pond]

According to the information I found, it cannot be repaired.

[solar thicket]

damn

okay thank you so much for your help

[pliant pond]

However, the original extruder is very expensive, while the all-metal gear set is cheaper; perhaps you could try that first.

[solar thicket]

i will do that thank you

[pliant pond]

My current feeling about using this K1C is that the heating module and extruder drive me crazy every now and then.🫠

[solar thicket]

i ordered a new set of metal gears hopefully they work, thank you so much for your help!

[tulip plank]

Did you fully strip down the hotend and extruder to make sure there no blockages?
When you looked at the gears did the look visibly ok?

[solar thicket]

the gears did look okay as far as i could tell

i tried methods to unclog and that didn’t seem to be the problem either

[tulip plank]

Don't about the K1 but previous Creality printers used to have plastic extruder frames which were known to split - then you have to tension to push the filament

[tulip plank]

Did you try heating up to printing temp, releasing the tension and pushing filament through... if so did it move through pretty easily?

[solar thicket]

wdym by releasing the tension?

[tulip plank]

Can you unscrew/loosen the gears so they don't hold the filament- making it easy to push through by hand

Just googled apparently you can adjust the grip tension, many comments on same issue

If PLA leave door open and lid up, the chamber needs to be pretty cool.

Some people also said that after a full strip and clean that they leave the cover off to help with heat dissipation away from the heat break

[solar thicket]

so i tried the new gears and it still doesn’t work

[solar thicket]

i tried loosening them

it wouldn’t print however when i clicked extrude a bit of filament did come out

previously none would

[solar thicket]

so i figured it out
