Grbl - An embedded rs274/ngc (g-code) interpreter, cartesian bot controller, readout and exerciser for the AVR series of microcontrollers. Inspired by the Arduino GCode Interpreter by Mike Ellery Status: * Linear interpolation machine control complete (No arcs yet) * GCode interpreter complete * Basic serial protocol complete * As of yet completely untested in a real environemnt. Still waiting for my micRo kit from Lumenlab.com Goals: * Runs on the atmega168 * Runs on the Arduino boards with at least an atmega168 * Suitable for both milling and deposition fabrication * Support GCode from common free and cheap CAM-packages right out of the box * Optional support for a alphanumeric LCD readout, a joystick and a few buttons for program control * Optional support for automated cutter length calibration when milling * Support "headless" fabrication by buffering all code to SD-card or similar Limitations: * No support for Arduino software (but will run fine on an Arduino board if you program it with an ISP) * Limited GCode-support. Focus on the kind of GCode produced by automated CAM tools. Leave human GCoders frustrated.
