The Bambu Lab TH Board FPC Cable is the OEM replacement flexible flat cable (FPC) that connects the toolhead control board (TH Board) to the printer's mainboard. This cable carries all critical data and power signals between the toolhead and the control electronics, including hotend temperature, fan control, and filament sensor data, enabling coordinated operation of all toolhead functions.

FPC cables can develop micro-fractures or connector wear over time due to the constant movement of the toolhead during printing. A damaged FPC cable can cause intermittent communication errors, random sensor drop-outs, or complete toolhead failure. This OEM cable is a direct replacement that restores reliable signal transmission between the TH Board and the mainboard.
