Placa CPU para impresora 3D Creality, modelo 4002020078, placa PCB de repuesto individual (1 ud.)

Replacement CPU board for Creality 3D printer, model 4002020078, single PCB replacement (1 pc) is a single-board control unit designed to restore or replace the main control functions of compatible Creality 3D printers. This printed circuit board provides the core processing and interface connections required to operate motion control, sensor inputs and heating outputs on CFS-compatible Creality machines. The unit is supplied as one complete PCB intended for direct swap into devices that use this board form factor.

Advantages

This replacement CPU board offers a direct replacement option that can reduce downtime by restoring printer control functions without replacing the whole machine. As a single PCB, it simplifies installation into systems designed for this board layout and removes the need to rewire multiple modular components. The board supports the primary control pathways for motion, temperature and user interface signals typical for Creality 3D printers.

Suitable for

• Repairing a Creality 3D printer with a failed main control board
• Routine maintenance to replace a degraded or intermittently failing PCB
• Workshops and service centres performing board-level repairs on compatible Creality machines
• Users needing an OEM-compatible single-board replacement for continued machine operation

Key specifications

• Function: main control (CPU) printed circuit board for 3D printer operation
• Form factor: single PCB designed to fit CFS-compatible Creality machines
• Quantity: one PCB per pack
• Interfaces: designed to connect to motion drivers, endstop and sensor inputs, heater and fan outputs, and user interface connections (exact connector types depend on printer model)

How to use

Power the printer off and disconnect it from the mains before beginning. Remove the printer cover panels to access the existing control board, noting and labeling cable connections if required. Carefully disconnect all connectors from the old board and remove any mounting screws. Install the replacement PCB in the same orientation and secure it with the original fasteners. Reconnect all cables to the corresponding connectors, ensuring firm seating and correct alignment. After reassembly, power the printer on and perform initial checks: verify firmware compatibility, confirm proper movement of axes, and test heater and sensor feedback before resuming normal printing.

Recommendations

Use only with compatible Creality printers that match this PCB form factor. Verify firmware compatibility and restore or update firmware settings as needed after board replacement. Handle the board with antistatic precautions, avoid touching exposed components, and ensure all cable connections are secure before powering the printer. If uncertain about installation or firmware procedures, consult official Creality documentation or a qualified service technician.
