I recently purchased a K2 Combo printer, and despite my experience with 3D printing, I’m struggling with a persistent quality issue. I also own an Ender-3 V3 KE, which prints flawlessly, so I’ve been able to compare results side by side.
I’m facing severe Z banding on the K2. No matter what settings I try in Creality Print or Orca (default or custom) the issue remains unchanged.
Here’s what I’ve already done:
Calibrated the belts to 110Hz
Tightened every screw I could find
Loosened the dual Z supports slightly
Lubricated the rods
Cleaned the nozzle thoroughly
For this test, i’m using Creality Hyper PLA (blue) filament
Filament dried to ~13% humidity in the CFS
Placed the printer directly on the floor for better stability to try
Despite all these efforts, the results are disappointing. I expected a plug-and-play experience, but I’ve spent countless hours troubleshooting with no success. I have read and view many things without success.
Wow, the way the problem gets worse as the height increases really screams loose screw, but you already went through that. I assume you did the calibration after the tightening, lubricating and moving to the floor as any of those would require re-calibration (as does shipping and delivery).
The oddly named “input shaping” calibration could help. It’s worth a try if you haven’t gone there yet.
I’ve done “input shaping” after each move of the printer but only ghost is resolved.
To be more precise of the problem, i’m printing a 90 deg corner with 1 wall like klipper resonance STL. I think about an extruder inconcistency and z wobble.
yes, with all the things you have tried, extruder inconsistency and z wobble makes sense. Since it seems to get worse as the cylinder advances in the z-axis, I’d go for z-wobbler first, but I’m not sure how to attack that one.
