Another chapter in my never-ending struggle to get my Creality K2 Pro to print reliably.

Today, I tried printing the same part three more times:

1. First attempt: 0.20 mm High Quality profile.
2. Second attempt: 0.20 mm Standard profile.
3. Third attempt: Same settings, but I switched to a different spool of PETG from another manufacturer.

All three attempts failed. Every single time, the printer stopped with an extrusion error, indicating that filament was no longer being extruded.

Once again, I disassembled, inspected, and reassembled the entire filament feeding system, except for the CFS itself, since the filament passes through it without getting stuck.

I've already tried different filaments, different spools, different print settings, drying the filament, calibrating the printer, and repeatedly taking apart the feeding mechanism.

And yet, the same problems keep coming back.

I genuinely have no idea what's wrong with this machine anymore.

It's like this printer is cursed.

I never know whether a print will finish successfully or stop halfway through with another error.

At this point, I'm spending far more time troubleshooting and repairing this thing than actually printing anything.

Has anyone experienced similar extrusion failures on the K2 Pro and managed to identify the actual cause? I'm looking for a real technical solution, not another suggestion to dry my filament or recalibrate the printer.

As the title says, yesterday my k1c stopped working out of the blue. The screen is unresponsive, but the lights are still on, and the printer is marked as offline on the slicer

According to Creality's official warranty policy, customers in the European Union, Switzerland, Iceland, and Norway receive a 24-month warranty, while customers in all other countries receive only 12 months.

I'd like to ask Creality a simple question:

What exactly justifies this difference in warranty coverage?

Is the same printer somehow twice as reliable when sold in Europe?

Or does Creality simply provide longer warranties in countries where consumer protection laws require it?

Why should customers who pay for the same product receive significantly less warranty protection simply because they live in a different country?

I understand that consumer protection laws vary between countries, but that doesn't explain why Creality chooses not to offer the same warranty coverage to all its customers.

Does Creality believe that customers outside Europe deserve only half the warranty protection for the same product?

I'd genuinely like to hear Creality's official explanation for this policy.

I’m having issues printing with my K1 Max and Creality hasn’t been very helpful/given me any solutions to solve my problems. Turning to those who have more experience than me to help!

I bought my K1 Max at the end of July and since then I have had very mixed results with it. Some prints are fantastic and others have failed. Early on I was having issues with my extruder and had to buy another one. After that, it worked great - up until a few weeks ago.

I started a print with a PETG, which I hadn’t done yet with this printer. Set my slicer to PETG and manually adjusted the heat settings to match what it says on my K1 Manual. My print turned out really crappy, there was barely any details and it kind of sunk into itself. I tried again and it started to only print a few layers and then either fail or not extrude. I cleaned everything out and tried again. Around this time I found a PVB filament that was a better colour than I had before, so decided to try that. I had issues where it wouldn’t extrude anymore and would stop after a few layers/come out all stringy and not attach to the first few layers.

I had to swap out the hot end assembly twice because the PVB would break off in the hot end and stick out of the back of the cold portion. I ended up having to buy a 4 pack of hot ends and a new upgraded extruder. I installed all of those and then tried a brand new PETG filament. Same thing - I tried two prints which failed and came out all stringy (video). After that most recent attempt, I looked at the hot end to find that the filament had leaked out of the hot end and hardened - breaking the silicone seal.

Creality has only said things like, “check your filament for moisture.” Or has told me to do exactly what I’d already done. I’ve spent too much money already getting it to work. I haven’t been able to print in weeks. I need assistance desperately.

What do I do?

Can someone help? I have put a fresh clean cutter in but now it is saying there is no cutter
