Printing very bad overhangs with PETG and 0.3mm nozzle

Hi,

I use an old and very heavily modified Ender2 with a gear extruder (short bowden), original E3D V6 with a 0.3mm nozzle that delivered really excellent results with the old slic3r (including overhangs!).

Everything prints well except overhangs - those really look terrible at 45° already (see picture - tail and also the corners of the neck).

I calibrated extrusion, e-steps - all belts are replaced and tensioned well. Cooling runs well.

Even though Prusa Slicer is so much nicer to work with and also delivers excellent results with all my other printers I cannot resolve that problem on the 0.3mm Ender only.

Can anyone gibe me advice what I could be missing.
