RAMPS 1.4 is designed as an extension of the Arduino Mega and can be used to control a 3D printer or CNC.
This is an expansion board design for the user’s need for a RepRap in one small package for low cost. This is an all-in-one design plug in shield which fits the necessary components for a 3D printer, while being compatible with Arduino Mega.
Spesifcation:
Supply Voltage : 12 V
Fused at 5A for additional safety and component protection
Heated bed control with additional 11A fuse
Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.
I2C and SPI pins left available for future expansion.
2 stepper motor for Z axis in parallel.
Features :
Standard interfaces (as that of extruder)
Reserved GCI like I2C and RS232
MOSFET 3 MOSFET are apply to the heater/ fan and thermistor circuit.
Another 5A added to protect the component parts.
An 11A fuse is add to the hotbed.
Support 5 stepper drive board
The adoption of Pin Header as pololu makes it more convenient to repair or change.
I2C and SPI are reserve for expanding
All the MOSFET can be controlle by PWM
Use the interface of servo motor to adjust the level of printing platform automatically.
Adding a SD module for SD ramps module.
LED can indicate the status of the heater (the open and close of MOS).
Expandable to control other accessories.
