Smoothieboard is a controller board for Reprap 3D printers. It is a descendant of other Reprap electronics like RAMPS, RAMBO and Melzi.
The main design change from older boards that is uses a more powerful ( ARM 32bits ) Cortex-M3 Microcontroller.
The board is named Smoothieboard, and the firmware that runs on it is called Smoothie.
The Smoothie project's main design goals are :
- Ease of use and configuration
- High performance ( faster speeds, smoother motion, thus the name )
- Also works for laser cutters and CNC mills
- Ethernet ( web interface ) support
- Easy to contribute to, feature-rich
- Strong documentation effort ( beginner-friendly, coherent, up to date documentation )
Features
- Smoothieboard
- ARM-Cortex M3 LPC1769 ( 120Mhz, 64kB RAM, 512kB Flash ) Microcontroller
- USB2 interface
- Ethernet interface
- MicroSD card slot ( comes with a 4GB SD card, filled with documentation and host/slicing software packages )
- 5 stepper motor drivers ( A4982, for stepper motors rated up to 2 Amperes ), well cooled on-board, 1/16 microstepping
- Digital current control ( no need to use a screwdriver to set a potentiometer for current setting )
- 3 ZXMN4A06 ( 5A, up to 24V ) small mosfets for hotends and fans
- 3 AOT240L ( 12A, up to 24V ) big mosfets for hotends, fans and heated beds
- 12 to 24V power input
- Optional Voltage Regulator so the board can run without a host computer
- 4 Thermistor inputs ( 12bit ADC ) for thermistors
- 6 Endstop inputs
- Extensions : SPI, I2C, PWM, DAC, free GPIOs
- Un-pluggable screw terminal connectors for easy wiring
- Everything broken out for easy hacking and inventing of new things
- Open-Source Hardware, community developped
- Smoothie firmware
