Very good results! Thanks for sharing!

Any advices or tips that lead you to these results?

Hi! Let's see if i can remember everything xD

First things first: I advise against using any gcode unless you understand what you are doing. When in doubt take a look at >this page<

> Then i stumbled upon Z axis skipping steps, which was solved by reducing Z axis speed/accel. (2mm/sec and 40mm/sec^2 worked well for me) You can either do that by reducing "Machine Limits" in prusa slicer (can't say about other slicers, i'm new to 3d printing xD) or by adding the following GCODE into your start gcode.

M201 Z40 ; sets maximum accelerations, mm/sec^2
M203 Z2 ; sets maximum feedrates, mm/sec

I tweaked the slicer settings, but the gcode would probably be better, so you don't get slow Z axis during calibration.

There i took the idea of custom pre-calibration procedure. [modified "Z Azis Height Adjustment" gcode] which further improved the stability.

> Page (2) also provides a nice temperature calibration tower, which i modified for my needs (PLA, 215*C-195*C)
My filament worked well at 205*C for 0.1mm layer height, but i increase it all the way up to 215*C when printing at higher layer heights, because i faced severe underextrusion at lower temps.
