[H2C] Rear fan / ventilation error + loud clicking noise from rear vent area
Just got my new Bambu Lab H2C and I’m having an issue during setup/calibration.
The printer gives me a ventilation/fan error, and there’s a loud “clac clac clac” noise coming from the rear of the machine.
At first I thought it was just the rear louvers/flaps not opening correctly, but after checking more carefully, the noise actually seems to come from underneath the louvers, near the rear fan grille.
It almost sounds like:
- a fan blade hitting something,
- a cable touching the fan,
- or the rear ventilation system vibrating because the louvers don’t fully open.
The louvers also make noise when closing.
Has anyone experienced this on the H2C?
Factory assembly issue maybe?
Thanks!
