TinyG Start

If you have just received a TinyG this is the place to start.

What is TinyG?

The TinyG project is a many-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. Here are some of the main features:

*Full, integrated motion control system with embedded microcontroller (Atmel ATxmega192) and 4 stepper motor drivers (TI DRV8811) integrated on a ~4 inch square board *Accepts Gcode from USB port and interprets it locally on the board *6-axis control (XYZ + ABC rotary axes) *Acceleration planning performed using constant jerk motion equations (3rd order S curves) for very smooth and fast motion transitions for lines and arcs *Very smooth step pulse generation using phase-optimized, smart oversampling, fractional step DDA running at 50 Khz with very low jitter (<<1uSec) *Networkable via RS485 to support motion peripherals and for networking mutliple boards for multi-axis systems and for really interesting projects (up to 1000 stepper axes) *Stepper drivers handle 2.5 amps per winding which will handle most motors up thru NEMA23 and some NEMA34 motors. *Microstepping up to 1/8 (optimized DDA makes this smoother than many 1/16 implementations)
