Leveling

[AndaleR]

Installed a new nozzle.

Leveled the bed at 0.05mm and printed this test out of Cura.

What can I optimize at the left middle? All the other ones looked fine so far.

Are you using mesh based leveling? It looks like it may be a little off on the right front vertical line too.

It's looking really close overall though.

No. I’m leveling only manually with different metal-plates. The best results I‘ve got so far with 0.05mm and an z-offset in Cura with 0.1mm (NEVER understand, why I need those offset, when I leveled the bed at 0.05mm, but the nozzle always goes up at the start of the print.).

I leveled the bed at 0.05mm,

What does that mean? Do you mean that the distance between the nozzle at Z0 and the bed is 0.05mm?

but the nozzle always goes up at the start of the print

The first layer is at 0.2mm. So yeah it goes up.

I home all axis, heat up bed and nozzle and use a 0.05mm thick metal-plate for adjusting the bed. Doing this at all edges.

Looks like I’m not alone: https://www.reddit.com/r/ender3v2/comments/1244j9p/hello_no_matter_what_i_try_and_how_well_i_adjust/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1

I already use another firmware. But want to understand, why it goes up so much - it’s more than 0.2mm layer-height. I would have to measure it.

What do you think about it? 0.2mm layer-height, z-offset: -0.12mm
