I remind this model which I tested on my Qidi printer (I still have aside the K2) and id tid not work out of the box.
The reason is that even side/auxiliary fans cannot cool the internal overhangs because of the model is blocking the airflow with the bigger external part.
I had luck by setting X-Y-contour compensation to -0.1 mm (On Qidi I used -0.15) and using my standard 0.2mm profile with Elegoo RAPID PLA easily!
One other comment on the K2: 90% of my PLA & PETG need a corrected filament profile (see my method here) if you do not want to use full calibration on every print.
The standard ‘General XXX profiles’ do generate no good outcome because on 90% they produce over-extrusion or bad PA values.
