I 'll find some time, possibly this weekend and start a thread with photos an configuration.

I haven't managed to fix this either. I improved the result by perfecting bed leveling and extrusion and especially pressure advance. Still, the result is worse than that I had (with Klipper) before upgrading:

• More horizontal lines
• More ringing
• Characteristic corner artifacts (above and below the letters)

I get the exact same cali cube. I have an Ender 3 Pro with Duet Ethernet, BLTouch, Bondtech BMG and E3D V6 Gold Edition.

As you can see in @rybar94 's photo, the heavy extrusion issues appear mainly in the corners of one or both directions and under or above the letters. Other than that, there are a lot of horizontal lines appearing throughout the print.
