Simen Svale Skogsrud 36fd3a9bfb improved the serial protocol, added some debug pins for a while
2010-03-02 08:19:21 +01:00
arc_algorithm lots and lots of bugfixes after running on reals hardware for the first time 2009-02-03 09:56:45 +01:00
gcode Fixed a number of bugs caused by using abs() on floats and long ints. Added support for selectively inverting bits of the stepping port. Debugged, optimized and cleaned up timing code for the step-pulses. 2010-02-27 19:55:09 +01:00

Grbl - An embedded rs274/ngc (g-code) interpreter, CNC controller, readout and exerciser for the AVR series of microcontrollers.
Inspired by the Arduino GCode Interpreter by Mike Ellery

Status:
* Runs on atmega168/arduino.
* GCode interpreter complete
* Linear interpolation machine control complete
* Arcs and helical interpolation complete
* Buffered, non blocking, asynchronous stepping so the rest of the system is free to generate new steps and parse 
  g-code while the steppers are still steppin' 
* Basic serial protocol complete
* Stepper pulses verified on scope and tested with stepper motors, motion and rates verified with simulator,
  but not tested on real CNC-rig. Still waiting for my micRo kit from Lumenlab.com

Pending: 
* 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
* Smooth feed rate interpolation

Limitations:
* Limited GCode-support. Focus on the kind of GCode produced by CAM tools. Leave human GCoders frustrated.
* No rotation axes, only x, y and z.
