New part arrived Friday. My super-temporary repair is still holding up, and I have the printed braces and fittings to install if/when it gives out. Not planning on installing the new part, don’t feel like picking metal pieces out of my extruder again. This experience was informative, now I know I can’t rely on Creality CS at all, and this will likely be not only my first, but also last Creality printer.

I had the same issue. Thanks to this thread my printer is up and running. I’m still waiting on the replacement door since the hinge wasn’t attached to the glass…. 2 months ago now.
If you try to rely on Creality CS you may as well give up.
I used this print:

With these parts:
3Dman PC4-M10 Male Straight… Amazon.com: 3Dman PC4-M10 Male Straight Pneumatic PTFE Tube Push in Quick Fitting Connector for E3D V6 Long-Distance Bowden Extruder 3D Printer Parts (20pcs) : Industrial & Scientific
The K2 came with silver screws that did the trick since they were a hair longer.
The fitting screwed right in.
I didn’t have any metal in my gears, which is fortunate. My neighbor has a Bambu printing so cranked a PTEG adapter out for me.
Oh but they did and reading about it there seems to be a lot of issues with it.
You are lucky they got back to you. Been waiting over a week and no customer service yet. I’m having this same issue, hopefully I can get this fixed
I unfortunately have the same problem with my K2. This is so disappointing as i replaced mine and it lasted one week. I have only had my K2 just over four weeks.
YEP glad i found this thread I was so confused, but exact same things just happened to me and ive wasted like 2 hours trying to fix it myself.
Even found the teeth of the cutter magnet after reading this.
I guess ill have to try the PC4-m10 connector + print or something.
What a total pain in the ass!
JUST AS A NOTE TO PEOPLE, You can make a quick and easy TEMPORARY FIX using masking tape, to tape the bowden tube in place, it withstands the push pressure, and allows you to print out a better solution like the ones posted above.
Hi, +1 having this issue, I reached out to Support and they are shipping me a new extruder front cover. The support process (for me) was quick / easy to log a ticket via the app and get a new part shipped under warranty, probably due to all the past issues already logged…
I printed this part using PETG /side spool to re-enable the CFS before I found this tread…

My question is, does anyone know if there is a more permanent extruder design/fix for this issue being developed ?
so far I’ve been hobby printing with above work around for a week and its allowed the unit to keep working, however I’m noticing that when I remove the PTFE tubing from the PC4 M10 to print TPU, its incrementally chewing up the PTFE tube, so I’ll need to be replacing that very soon.
I’m looking for variations of the M10 to see if there is one that won’t destroy the PTFE as fast but still hold the tubing.
