Las RAMPS son siglas en ingles para Raprap Arduino Mega Pololu Shield, se diseñaron con el propósito de ser usadas con los drivers de corriente POLOLU, como por ejemplo con el chip A4988. Las RAMPS solo pueden ser usadas con un arduino MEGA2560 y drivers A4988/DVR8825. Tienen una gran estabilidad de operación y gran compatibilidad con la mayoría de las impresoras 3D del mercado (reprap prusa i2 i3 etc).
Weight: 68g
Size: 102mm*60mm
Standard interfaces (as that of extruder)
Reserved GCI like I2C and RS232
MOSFET 3 MOSFET are applied to the heater/ fan and thermistor circuit.
Adding another 5A to protect the component parts.
An 11A fuse is added 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 reserved for expanding
All the MOSFET can be controlled 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).
2 stepper motor for Z axis in parallel.
