Ramps 1.4 This list is Pololu trillion rupiah , or ramps short. It was designed as a low-cost small package RepRap needs to accommodate the entire electronics . Oblique interfaces with the powerful Arduino MEGA platform Arduino Mega , and have plenty of room for expansion. On the stepper drives and a Arduino MEGA shield extruder control electronics for easy maintenance , replacement parts , upgrades and expansion capabilities , including plug-in modular design . In addition, some Arduino expansion boards can be added to the system , as long as the main ramp plate is saved to the top of the stack The board is mainly based on Adrian 's Pololu_Electronics and work Tonok 's . The proposed anti- Vick copper etching method . Vick is also inspired by the work of EasyDrivers . Adrian'sPololu_Electronics circuit design mainly based on Joaz RepRapSource.com provide initial pin definitions and many design improvements. Too much inspiration , advice, and from Prusajr, Kliment, Maxbots, Rick, and many other ideas RepRap community
It has Cartesian robots and regulations of the extruder Extended to control other accessories Heater / MOSFET outputs and three fan thermistor circuit Integration of additional security 5A and component protection Control of additional heating bed 11A fuse Suitable for 5 Pololu stepper driver board Pololu board pin socket, so they can be easily replaced or removed for future designs I2C and SPI pins left for future expansion Hooked into all MOSFET PWM pin versatility Servo type connector is used to connect to the end stop , the motor and the light-emitting diodes. These connectors are gold-plated , rated current of 3A, very compact On the SD card to add - is now available from the Kliment - Sdramps LED indicate when the heater output Option 2 motors connected to Z Prusa Mendel
