#3503 Hood fan speed

On the ULTRA you have two modes for the ventilation of the hood:

1) The automatic mode will manage the fan speed according to the ventilation and temperature needs. You can enable this feature via the MENU->CFG SYSTEM->Ventil. Auto cover.

2) Manually, if you disable the Auto ventilation, you can set this ventilation via the MENU->Config Miscellaneous->Fan speed

Don’t forget to save the settings if you want them to stay that way.

Caution, in manual mode, do not under-ventilate the cover as this can lead to overheating of the extruder. Filament blockages can therefore cause printing to fail.
