The Reprap RAMPS 1.4 Pack + Arduino Mega + 5 A4988 stepper drivers is an electronic kit specially designed for controlling RepRap-style 3D printers and CNC machines with up to 5 axes. Thanks to its compatibility with firmware that interprets G-code, this pack enables efficient and precise numerical control.
This kit includes essential components to get a RepRap 3D printer or a CNC machine up and running with a maximum consumption of 2 amperios per axis. It is equipped with 5 "Stepstick" drivers using the Allegro A4988 integrated circuit, known for overcurrent protection and thermal shutdown, ensuring safety and durability.
Main features
- Arduino Mega 2560 Rev 3 compatible: powerful and versatile microcontroller for managing multiple axes and functions.
- RAMPS version 1.4 board: interface for connecting the drivers and controlling stepper motors, hotend and heated bed.
- 5 Stepstick drivers with A4988 integrated circuit: motor drivers with heatsinks to prevent overheating.
- 2 low-power mosfets and 1 high-power mosfet: allow control of elements such as the hotend and heated bed.
- USB cable included: to connect the Arduino Mega to the computer and upload firmware or send commands.
Recommended uses
- Base electronics for RepRap-style 3D printers.
- Control of CNC machines with up to 4 axes and maximum consumption of 2 amperios per axis.
This pack is the most economical alternative on the market for those looking to build or repair 3D printers and CNC machines with reliable, compatible components. Its modular design allows easy integration and upgrading.
Compatibility
Compatible with standard firmware that uses G-code for numerical control, ideal for DIY and professional projects that require a flexible and economical solution.
- Compatible Arduino Mega 2560 Rev 3 included
- RAMPS version 1.4 board for motor and heating element control
- 5 Stepstick drivers with A4988 integrated circuit and heatsinks included
- Control for RepRap 3D printers and CNC machines with up to 5 axes
- Temperature cut-off and overcurrent protection in the drivers
- Includes USB cable for connection and programming
Customer Questions & Answers
What are the main benefits of using the RAMPS 1.4 + Arduino Mega + 5 A4988 pack in a RepRap 3D printer compared with more modern all-in-one boards?
The RAMPS 1.4 pack offers modularity for individual component replacement, low initial cost and extensive community documentation. However, all-in-one boards usually integrate advanced protections, allow higher current capacity and offer options such as silent drivers or other sensors, at the expense of less flexibility and a higher price.
What voltage and current does each included A4988 driver support, and how does this affect the type of motors I can connect?
Each A4988 driver supports up to 35 V DC and a maximum output current of 2 A per phase, although operation around 1.5 A is recommended for thermal reasons. It is essential to use stepper motors that do not exceed these values and to adjust the Vref on each driver to avoid overheating.
Are there any particular electrical safety precautions or temperature limits for these A4988 drivers?
Yes, the A4988 includes automatic cut-off in the event of overheating (>150 °C approx.) and overcurrent POR protection. It is recommended to fit heatsinks and ensure effective ventilation to avoid damage, as well as checking the input connections (requires 12-24 V DC depending on configuration).
What components are included in the Reprap RAMPS 1.4 pack?
It includes a compatible Arduino Mega 2560 Rev 3, a RAMPS 1.4 board, five Stepstick drivers with A4988 integrated circuit and a USB cable.
What type of printers is this pack suitable for?
It is suitable for RepRap-style 3D printers and CNC machines with up to 5 axes and maximum consumption of 2 amperios per axis.
Do the drivers have overheating protection?
Yes, the Stepstick drivers with A4988 integrated circuit have thermal shutdown and overcurrent protection.
Can this pack be used to control a heated bed?
Yes, the RAMPS 1.4 board includes mosfets that allow control of a heated bed and a hotend.
What type of firmware is compatible with this kit?
It is compatible with firmware that uses G-code for numerical control, common in 3D printers and CNC machines.
