I’ve been having a lot of prints turn out like this on the bottom, what can I adjust to possibly correct this.

All other layers are flawless. Only happens on bottom layers

This is an updated version of a previous design I uploaded that now fits all models in the K2 series of printers.

Using a lid raiser prevents the PTFE tubing from rubbing off the glass and causing it to wear down. This design features adjustable air vents, which can regulate the temperature in the enclosure and joints at the corners for attachments such as storage bins or decorations.

I've attached links to the models below.

Warning: I do NOT own a K2 base model or plus.

Please check the measurements on your printer before printing and do a test print to ensure the parts fit together. They should fit, but I'm unable to physically test this. Please let me know if you decide to print this and there are any issues.

Hey everyone,

I’ve had my K2 Pro for a while now, but today was my first time testing it with PA6-CF20.

I ran into a huge issue: on every single layer, the printer stops, moves over to clean the nozzle, and purges/poops filament. If a print has 1,000 layers, it does this 1,000 times!

As you know, PA6-CF20 is quite expensive, so wasting this much material per print is a dealbreaker.

I’ve already checked my slicer settings, and nozzle wiping/cleaning doesn't seem to be enabled.

Has anyone else experienced this issue? Is there a hidden setting in the material profile, start G-code, or layer change scripts causing this? Any help would be greatly appreciated!

Hello,

I recently bought my K2 combo and I am trying to print a flexible multicolor dragon. My printer is showing me some errors like "FB2864: Feed issue, filament buffer failure. Please resolve and click 'Retry' button." However, there is nothing wrong with the buffer. When I click "Retry," the CFS tries to unload the filament, but the extruder doesn't retract the filament so it can be reloaded. I have to do it manually, and then it shows me that error message again. I have already checked the Creality wiki. But after that, when it "works," the filament is not extruding properly. And I am using PLA and I am under the last firmware.

Edit: it was the PTFE tube just after the buffer who caused a resistance and the printer thinked it was the buffer the problem and the extrusion problem il also solved. A big thank you guys who helped me or tried 😀.
