RAMPS 1.4 3D Printer Control Shield

The RAMPS 1.4 3D Printer Control Shield is the go-to solution for DIY 3D printers and RepRap-style machines, offering modular and open-source compatibility with the Arduino Mega 2560. It allows full control over stepper motors, heated beds, thermistors, endstops, and LCD displays, forming the core of many hobbyist and professional 3D printer setups.

Whether you’re building your first printer or upgrading an existing one, RAMPS 1.4 is designed to simplify the integration of all essential components. With slots for 5 stepper driver modules (like A4988 or DRV8825), the shield supports X, Y, Z, and dual extruder axes, plus a heated bed.

Use it alongside components in our Electronics Components section, and don’t forget to grab your Power Supply for stable 12V–24V input.

Precautions

• Always disconnect power when connecting/removing drivers.

• Ensure proper orientation of stepper drivers to avoid burning the board.

• Use active cooling for stepper drivers during prolonged prints.

• Verify firmware settings before testing heated elements.

• Fuse protection is recommended when using high-current heated beds.
