TinyG CNC Controller

Has anyone used a TinyG CNC Controller? What was your experience with it? Looking for something inexpensive to drive a four-axis hot-wire cutter. The acceleration planning is very cool, but probably not necessary for hot-wire.

Product Details

The TinyG is a hardware and firmware project that is a multiple-axis motion control system. It is designed for small CNC applications and other applications that require highly controllable motion control. TinyG is meant to be a complete embedded solution for small/medium motor control.
  • Up to 6 axis (XYZ + ABC rotational axes) control with drivers for 4 axes on board.
  • Working Voltage: 12-30VDC (24 is Ideal)
  • Stepper drivers can deliver up to 2.5 amp per winding.
  • Selectable micro-stepping up to 1/8.
  • Acceleration planning performed using constant jerk motion equations (3rd order S curves) for very smooth and fast motion transitions for lines and arcs
  • Full, integrated motion control system with embedded microcontroller (Atmel ATxmega192) and 4 stepper motor drivers (TI DRV8818) integrated on a ~4 inch square board
  • Accepts Gcode from USB port and interprets it locally on the board
  • Easily upgraded by the user with a few commands through the USB port.
  • RoHS compliant.
TinyG is open source. The documentation can be found here.
