Synthetos - TinyG CNC Controller Board v8

The TinyG project is a multi-axis motion control system. It is designed for CNC applications and other applications that require highly precise motion control. TinyG is meant to be a complete embedded solution for small/medium motor control. Here are some of the main features of the v8 hardware.

• Integrated motion control system with embedded microcontroller (Atmel ATxmega192)
• 4 stepper motor drivers (TI DRV8818) integrated on a ~4 inch square board
• Stepper drivers handle 2.5 amps per winding which will handle NEMA17 motors and most NEMA23s
• Accepts Gcode from USB port and interprets it locally on the board
• 6-axis control (XYZ + ABC rotary axes) maps to any 4 motors
• Constant jerk acceleration planning (3rd order S curves) for smooth and fast motion transitions
• Very smooth step pulse generation using phase-optimized fractional-step DDA running at 50 Khz with very low jitter
• Micro-stepping up to 1/8 (optimized DDA makes this smoother than many 1/16 implementations)
