Underextrusion at layer change when printing at high speeds.
I'm running into issues when printing at higher speeds on my VC3 400. The issue is independent of the used filament manufacturer. I currently print PETG that's been in a food dehydrator for 24hrs, so probably as dry as you can get.
Setup is a NF-Crazy (Mosquito-Clone) with a Volcano-Style Block (Like the Volcomosq, but also by Mellow). The nozzle is a CHT-Clone 0.6mm with a CNC Volcano nozzle adapter. The setup itself is quite capable in the sense that you can melt a shitton of material at once, but i get really ugly layer changes:

I've already tried calibrating retraction but most testprints are so small that the slowdown kicks in and i can basically print perfect outer walls with any retraction length between 0.1 and 1.5mm.
Once I go above say 100mm/s on a 0.6mm nozzle... things look different, as you can see. I've gone as far as completely deactivating retraction but to no avail.
I am also no longer sure if it is really underextraction or just filament not sticking properly and getting ripped away.
Oh, I nearly forgot: I've deactivated pressure advance already.
