Just hit that problem today: The filament tubing needs to be straighten out, pull the tubing out of the cable guide and do not let it bend more than 40°, when you feed filament through the tubing it shouldn’t bind up. I disassembled my extruder, cleaned it with Everclear and a fine brush and tested, the K1 is back! I can only guess that the filament partials was causing the teeth to slip in both directions leaving the mess it made.
I have also encountered the clicking extruder. In my case I had a print fail where it got a signal of filament run out, but then later restarted and printed the remainder in the recognizable “starving for filament” style. The filament was TPU so I don’t believe flexibility is an issue. So I think that leaves me with 2 questions (which I think I know the answer to 
):
- Is the clicking the death rattle of the 2 month old extruder, and I have to get a new one?
- It there any possibility that this is covered by warrantee?
(Survey says… “Yes and NO!”
)

In my experience on the K1 and K1 Max the clicking extruder syndrome is when the extruder can’t push the filament through and the gears are just slipping.
Sometimes that filament clamp on top is not pushed all the way over. I’ve seen it work it’s way loose on the earlier models of the extruder.
It could also be a clogged nozzle or hot end or…?
jimandyen,
It was a dead extruder. It also fixed my problems with the Hyper PLA tearing on my calibration cats. I will need to rerun the fine tuning for Hyper PLA as the extruder was probably influencing results. I am looking forward to getting some printing done! (Now if only I could figure out what to do with the belts…)

Spoke too soon, still have extrusion problems.
I have the upgraded extruder and I can’t seem to have this thing to stop clicking on me. I see on the web that we need to adjust the E-steps, but it is only on the devices that they have on their videos. So Firmware stuff. The K1/K1-MAX/K1C we need to adjust that on the Creality Print. So I go under Extruder and find it is harder to understand what needs adjusting. I have looked at the filament and I can see that the string is squished which is causing the issue. So I am thinking that the Retraction might be part of the issue. So it is something called “Heat Creep” is the problem. One way that I have found that the faster you push the filament out of the nozzle that heat creep will not affect it because the heat cannot creep up fast enough. I have tried to disable the retraction, it does help with the issue but still doesn’t fix it. There is another, yes I do like higher quality looking prints but instead of going 0.08mm, 0.10mm, or 0.16mm. Just run 0.20mm and that filament is pushed out faster. I have a lot less chance for it to jam up. I still use Creality Print 4.0 and I do have 5.0 as well. I have seen that the retraction speeds are different. 4.0 has the retraction speed of 40mm/s while 5.0 has 30mm/s. I don’t know if this will help but I will need to test this out and find out.
But overall, I know the faster the flow rate is the less chances of it jamming up on you.
Just adding a little something here. I don’t know if this is in 5.0 but 4.0 under “Material” has an advanced setting called “Sudden Flow speed gradient.” I looked it up and it adjusts itself with the amount of flow. I haven’t tried it out because I have something going on my printer right now. But I am going to try it out on my next print. Looks like something I can get behind.
OK. I have been working on this for a couple of months with my K1 Max and I found that in Creality print there is a Auto temperature, and on the printer itself has a AI max flow function called “Motion Advanced” I turned on all the AI functions and that fixed all issues. The reason why I had these functions off was the firmware wasn’t good a few months back, failing all my prints. Those functions are working correctly now.
So in the long run, in Creality Print turn on auto temp and on your K1 Max (If you have this model) turn on all AI functions and this will save you.
i have no idea why mine is randomly stops feeding.
Hello,
i had same problems with the first layer. But it not comes only from the extruder.
What i have was an noise too during the print.
The reason for this was that the drive gear wheel from the extruder has scratched the operating lever (open and fix lever) of the extruder.
I filled away some from the lever and no i have no noise.
It go now smooth.
But that not solve all first layer problems. Since firmware 1335 i had the problems. Since they added the Z offset. Now I must calibrate many thinks new. flow rate temperature preasure and more.
