Dual Power MK2B PCB Heated Bed – 12V / 24V Heatbed for Prusa i3 & RepRap 3D Printers in Pakistan

Overview

The MK2B PCB Heated Bed is the industry-standard thermal printing surface for open-source 3D printers. A heated bed is critical for preventing warping and ensuring proper first-layer adhesion when printing with materials like ABS, PETG, and even standard PLA. This board features a clever dual-trace circuit layout, allowing you to choose between 12V and 24V operation simply by changing your solder wire connections on the power pads.

Key Features 

• Dual Voltage Flexibility: Safely configure the board for either 12V or 24V power systems depending on your printer’s control board.

• Uniform Heat Distribution: High-quality copper traces ensure edge-to-edge even heating, eliminating cold spots that cause print failures.

• Pre-etched Center Hole: Features a central hole on the front side to easily mount an NTC 100K thermistor directly against the glass or print surface.

• Durable FR4 Laminate: Built on industrial-grade fiberglass substrate to withstand hundreds of thermal cycles without warping.

Technical Specifications

Wiring Guide (Quick Reference) 

• For 12V Operation: Solder the positive (+) wire to Pad 1, and the negative (-) wire to both Pad 2 and Pad 3 bridged together.

• For 24V Operation: Solder the positive (+) wire to Pad 2, and the negative (-) wire to Pad 3. Leave Pad 1 disconnected.
