The MKS Gen V1.4 is a high-performance 3D printer control board that integrates and improves upon the RAMPS 1.4 and Arduino Mega 2560. Designed for Reprap 3D printers, this all-in-one solution eliminates the complex wiring and fragility issues of separate RAMPS and Mega boards while maintaining full compatibility with Marlin firmware.
This MKS Gen V1.4 mainboard supports interchangeable stepper motor drivers such as A4988 and DRV8825, making it versatile for different printer setups. The board is built on a high-quality 4-layer PCB, ensuring better thermal performance than the traditional 2-layer RAMPS board. Additionally, it features MOSFET heat dissipation for improved efficiency and durability.
One of the standout features of the MKS Gen V1.4 control board is its wide voltage support (12V-24V), effectively reducing heat generation and improving power efficiency. It also retains RAMPS 1.4 interfaces such as AUX-1, AUX-2, and Servo ports, making upgrades and customizations easier.
For users looking for a reliable and efficient 3D printer mainboard, the MKS Gen V1.4 is an ideal choice, offering seamless firmware compatibility, modular driver support, and enhanced power management.
