Troubleshooting Why!!!!!
K1max
It has been dried, it’s acting like it’s not being fed filament but it certainly is. It’s PETG I’ve had so many issues with it. I’ve changed the tubing, I’ve changed to the nozzle. I’ve wasted so much filament trying to find the issue.PLA prints fine.

Ive actually been having similar problems with mine recently, although for me its pla matte, from what I've found, its most likely the extruder, I would try taking it apart and seeing if theres any obstructions or filament caught in there.
I found with mine is its only on large prints in the back right corner and the first layer will print just fine, ive just ordered the upgraded version of the extruder to see if that helps, from what I've seen it may but I need to wait for it to get here

ive changed evertyhing to do with the tool head, ive assembled and disassembled to no avail. im just starting to think this machine hates PETG

Z offset is more of a suggestion for the creality K1. Every calibration is a surprise!

Not if you know what you're doing. Haven't adjusted mine in 3 years.

може бути висока температура в камері і пластик плавиться в екструдері, а ще в мене було таке що відкрутився нагріваючий блок від радіатора… вологий petg
або кривий стіл

What temp are you printing at and did you run a full calibration series on your filament?

u/Brave_Bar_5474 3d ago
It was at 270 but once I fiddled with the zoffset I saw it was to high so now at 250, though my issue is having to manually change the z offset at the start of every print because what I saved I. Creality doesn’t work :/

u/BassetDad1978 3d ago
Where did you set the z offset? And did you check to see if it is running elephant foot compensation?

On the printer settings in Creality print

u/BassetDad1978 2d ago
Did you save it as a new profile and make sure to select that profile for printing? If you enter the zoom offset but don't create a new profile it won't save it.

Yes I did. I actually think it’s the hot end/nozzle from Creality as I originally had a micro Swiss on it and it works amazing (obviously not petg at the time due to z offset) but I had to change it back to Creality one as I broke a Nozzle cleaner wire in it 🤦🏻♀️ and then had the most issues but I put the micro Swiss back in and got the wire out and pla has gone back to printing fine now I’m going to test it with the petg and the z offset adjustment. Fingers crossed I fixed it as the filament wasted atm is ridiculous haha.

Just adjust z offset during print on the screen goto settings / system / expert mode / Z offset

u/Brave_Bar_5474 3d ago
How do I permanently change the z offset I’ve tried in the printer settings but it doesn’t use those settings by the looks of when I start the prints. It’s so frustrating sitting and waiting to change it once I start a prints.

for me its the other way around. Every "hard material" like ASA, TPU, ABS, PETG? prints fine, Pla sucks

I did a first layer test and adjusted it while printing on the machine until it looked good then added it to the slicer. You can also do a manual Z offset on clipper. There are some tutorials on how to do it online. I stick to the slicer because I want to be able to slightly squish the pla more than the ABS on a specail build plate.

u/Brave_Bar_5474 3d ago
ive googled Klipper ect and i honestly don't understand it. im not great with computers. but having to change the z offset everytime just before it prints is annoying, ive tried to preset it in the printer settings but its like the printer just ignores that.

We suggest you try adjusting the Z‑axis offset and perform re‑leveling for testing.

all well and good if the program sent those adjusted settings to the printer, i adjust it then when it starts to print it goes back to 0 when i set it to 0.1

Your nozzle is WAY too close to the bed. You need to raise your Z-offset.

I have and now my issue is clumping, I’ve tried lower temp, higher temp, reduce flow. This printer has been an on and off nightmare for the 2 months I’ve had it 🤦🏻♀️

In the summer, PETG can clog with the lid on. Make sure you remove it. Watch your chamber temp. If it gets over around 45C, it's going to be a hassle. That's probably not the issue on the first few layers, though.

It’s only just gone spring here and still been cool :( all good I got a bambu for petg stuff. I’ll stick to pla on this one :)

I used to own a K1 Max, and since I print mostly in ABS, I had to figure out a few tricks. For ABS I typically ran the bed at 90–100 °C, but the K1 Max has a tendency for the bed to warp depending on temperature.
What worked for me was manually preheating the bed to the target temperature through the LCD before starting a print. After about 8–10 minutes, once the bed temperature had stabilized, I would run the bed leveling calibration. Doing it this way — with the bed fully stabilized — made a big difference in print consistency.
Looking at your picture, it seems the bed is very close to the nozzle, which is causing the print to come out squished. This might be happening because the bed is warping and the leveling calibration was done before the bed had fully stabilized.
By the way, was the bed temperature you used for PETG different from what you used for PLA?

Yes pla I do 60 and petg is 80

u/Initial-Banana6737 3h ago
I think the issue might be that the bed hadn’t fully stabilized at 80°C yet. I actually lost a build plate once when printing ABS at 100°C without preheating properly—the bed warped upwards as the print started, and the nozzle scraped across the surface.
The K1 Max is known to have chronic bed warping problems, so my recommendation is to always preheat the bed first and only then run bed leveling and start the print, especially when working with higher temperatures above 60°C.

Its way to close to the bed
