Problem with nozzle grinding in Ender 3 V3 SE + Nebula Smart Kit

Ender Series Creality Ender-3 V3 KE/SE
1

Hi.

I have installed Creality Nebula Smart Kit to my Ender 3 V3 SE.
Before Nebula Kit printing was OK.
Now when i make calibration or print there is problem with Z axle.
Nozzle goes to deep in bed and even damaged the plate when cleaning the nozzle.
When i adjust z-offset for better printing, the first layer is printerd not to well but the second layer and the next ones goes even worst.
Nozzle is starting to grind the layers, like there is a calibration problem.
I reset the Nebula panel to default, try to install firmware NEBULA_ota_img_V1.1.0.27, NEBULA_ota_img_V1.1.0.26 and Ender3V3SE_firmware.bin but that didn’t help.
I try to decreas max speed and max acceleration in CrealityPrint printer profile but that didin’t help.

I don’t have any other idea what to do, could any boddy help?

Are you using Creality print 5.1 by any chance? Me V3SE does that, but it is on a Sonic Pad, either way both on Klipper. My fix was to go back to the older 4.3.8, weirdly 4.3.9 beta also does the scaping nozzle. I would Z adjusting for every layer and it would still scrape. Something fundamentally wrong with V3SE+Klipper+Cp5.1 for me.

Yes, I use CrealityPrint 5.1 witch Nebula pad.
Previously with old panel I used Cura3D to generate gcode.
What else strange with Nebula pad is that the gcode generated in Cura3D 5.8 and sent to Nebula to print or given on USB, rearranges the layers in the X or Y axes, while in the Z axis it is ok. It’s realy odd.

I will try older version of CrealityPrint and return with info.

So I ran tests on simple prints in Creality Print v4.3.8 and v4.3.9
Prints cut and send for printing are performed correctly in v4. 3.8 with Nebula Pad installed.
On version 4.3.9 the print is bad, something like in 5.x

Now my Ender-3 V3 SE is in configuration:
Nebula Pad - NEBULA_ota_img_V1.1.0.26.img
Motherboard - Ender3V3SE_firmware; Adaptive Ender-3 V3 SE
Creality Print v4.3.8 - with corected filament temp settings to 220/60

So it looks like the newer versions of Creality Print are buggy.
I will make a more advanced print and see what comes out of it.

Bonfireman thanks for the advice.

Thanks for confirming that I am not going mad and it isn’t my setup at fault.
