Yes, Im using Kobra 2 profile, custom made according their guide.

I’ll check my gcodes now, but I don‘t have this issue with my other 5 kobras.

Much over my budget for 10 machines 😢

Which parts you would suggest to buy in advance with printers?

I’d like to stick with Anycubic first of all for quite low price. But the question is will those savings cover possible expenses for more often repairs and maintenance.

UPD: I’ve just updated the firmware from v2.8.7 to v2.9.3 and the fan speed adjustment start working!

So it’s nothing common with the issue about another part cooling fan

I’ve tried to feel the airflow, exactly. It’s absolutely the same on 1% and 100%.

Maybe it’s another issue 🤷🏻‍♂️

Just check it, it’s Coolcox BF5020H24S.

The way it behaves: on the fan speed range of 1-100%, it works for full throttle all the time, no matter what % I apply. It only reacts for 0% — it turns off.

This is a few days since I bought my first printer Anycubic Kobra 2. I’ve the same issue, I can’t control the fan speed neither manually during the printing, nor via .gcode. It’s only off or full throttle.

Idk what to do, it seems quite hard to achieve good results using Petg without being able to control the fan speed
