Synthetos TinyG CNC Controller

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 most motors up thru NEMA23 and some NEMA34 motors 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 Networkable via SPI to support off-board devices and for networking multiple boards into multi-axis systems Microstepping up to 1/8 (optimized DDA makes this smoother than many 1/16 implementations)
