Printer Model

Voron 2.4

Extruder Type

Clockwork 2

Cooling Type

Stealthburner

After flashing new mainsail on my btt pi 1.2 somehow burn my fan0.
Before this fans work fine and after flashing i start with testing my printhead.
Hotend and hotend fan work fine, then i manually adjust part cooling fan and its burn out.

First i cant understand why its happen and is this critical damage to octopus ?

Hard to say what that happened but you can just move the fan to a new port.

Its work with another port. Problem is broken fan wire.
