Troubles with first print
Hi everyone,
I'm having trouble with my V-Core 4 500 (hybrid setup) and a 0.6mm nozzle. The first layer prints perfectly, but as soon as it starts the second layer or the infill, the 4028 fan kicks in at 100%. This sudden airflow causes poor layer adhesion and the print eventually fails.
Has anyone experienced this or knows how to fix it?
Any help would be really appreciated!

I mean if you already know that the fan is the issue right? Tune your cooling settings
How can I tune the cooling fan settings? What's happening is that the fan goes from 0 to 100% suddenly. I manually lower it to 30–40%, but after a few seconds it jumps back to 100% on its own.
Any idea how to fix this behavior?
yes - put better settings into your slicer?
What slicer do you use?
I used Cura and had no problems, but now I'm using Orca and I'm having some troubles. Now I'm looking for tutorials
Stick to orca btw - what filament type?
In orca you can change the cooling settings in the filament profiles under the cooling tab
I Tried with this setting, Worked a lot better but still perfectible. I'm using PLA+, this is the results and setting for the cooling;
100% for pla is definitely too much
let me search something for you really quick

i'm printing my high speed pla with 65%
thanks !
Can you please share with me your settings so I can have a good base to start ? (I Know I'm asking a lot 😅 )
my hs pla isn't really tuned, i only use it as support for petg prints, so i'm not quite sure if i can be any more help than telling you i'm using min 50% and max 65%
but even that can be a lot different between different brands
Perfect, will do the testing this weekend. Thanks for all your support!
