Tak našli, našli naši rádcové. A co že to hledali. Že by Marušku? Ale houby, Marušku, G-code interpreter a CNC kontroler s ARMem. Jasně, šlo se vrhnout do přeportování grbl, jenže na to jsem moc líný, takže jsem hledal a našel.

Features
  • Microcontroller
    • NXP LPC 1768/9 32-bits Cortex-M3 MCU, running at 96 to 120Mhz. 512kB Flash, 64kB RAM.
    • Drag and drop flashing : simply drop a new firmware file to the smoothieboard to update.
    • USB2 Composite device : shows to the computer as both a Serial device, and a Mass Storage device ( exposing the SD-card ), à-la mbed.
    • Ethernet
    • microSD card file storage.

  • Stepper drivers
    • 3 to 5 Allegro A4982 stepper drivers.
    • Each capable of driving bipolar steppers up to 35V and 2A.
    • 1/16 microstepping.
    • TSSOP package allows for much better thermal handling than commonly used A4983/8.
    • Digital control of the current setting for each driver instead of trimpot manual control.

  • Power outputs
    • Up to 3 SMT ZXMN4A06 ( 5A, up to 24V ) Mosfets sharing a power circuit
    • Up to three thru-hole ( AOT240L : 12A, up to 24V ) Mosfets sharing a power circuit

  • Power inputs
    • Main 12-24V ( Stepper drivers ) power can be connected using a 3.5mm or 5mm screw terminal, SMT power jack connector, or a Molex connector ( ATX-harddrive style )
    • 5V input can come from either a 3.5mm screw terminal, a SMT power jack connector, or a Molex connector as above. Or be taken directly from the USB cable.
    • Each of the two Mosfet couple can take its power from either its own 3.5mm screw terminal, or SMT power jack connector, or be connected to the main stepper driver circuit using jumpers.

  • Inputs
    • 4 Thermistor ( ADC ) inputs.
    • 6 Endstop inputs.
    • Play/Pause LED Tactile Button

  • Extensibility
    • SPI connector, I2C connector, Serial connector
    • Lots of pins broken out ( Including step, direction and enable pins for the stepper drivers, and mosfet pins )
    • 13 Additional GPIO pins broken out
    • 4 LEDs, many connectivity options

  • Firmware
    • Runs the highly-modular Smoothie firmware, see home page for more info.

  • Sources
    • Oh and by the way, it's all Open Hardware ( GPL-licensed ). You can find the Eagle files on GitHub.
    • If you are just hunting for part numbers, the bill of materials is also available in *.xls format on GitHub

  • Design
    • Dimensions are 130x105mm
    • 3D files can be found here on Thingiverse to design cases and plates and such.
