Steppers redirected to fastio.h from marlin firmware
min switches remaped to AUX-3, GBRL uses pin change interrupts
simple scheme to allow future porting of next releases
command buttons currently disabled
Ramps pins config moved to ramps.h
cpu_map.h - min switches
added GRBL_RAMPS1_4.ino for arduino IDE

Thank you for your project! There is a question: How to connect with your firmware display 12864 LCD, and most importantly it is a laser with ttl control? If it is possible to specify to which contacts to the ramps to connect the laser and ttl control? Thank you! P.s. I use your firmware for laser engraver.

Compiled without a hitch (after fixing some include file quotes). Worked out of the box (after fixing Z-axis homing issue, see the discussion section). Now my router is working! Very good work, thank you developers for your hard work.

it does not compile correctly on windows with arduino IDE... i tried running the makefile from cygwin , but there are some enviroment variables that are harcoded in the makefile.... i used original makefile from grbl , modified this line: DEVICE ?= atmega2560) and it compiles correctly !!! i loaded the firmware using xloader it loads but no magic serial promt....
