Drawing Machine V2

Update Oct 13 2017 BOM List Added STL file names updated to match with BOM list. GRBL CPU Map reset back to original settings. You can now connect X and Y Motors accordingly. Remix of 4XiDraw. Includes STL files, IGS files, Inventor 2017 project files as well as GRBL 1.1f with Servo Support. To operate this Modified GRBL 1.1f CNC Control Firmware, you need to link two stepper motors to the X axis and Z axis on the CNC Shield. My Arduino pin for Y direction is damaged so I made it work on the Z axis. Connect the Servo Sense wire (Yellow) to the Z- pin, Red to +5V pin, and Black or Brown to GND pin on the CNC Shield. I use Laser Web 4 to generate and send GCode to the machine. You need to alter GCode Settings in this software. Go to Setting -> GCode -> and fill in "M3S55" for Tool On and "M3S0" for Tool Off. To connect to Arduino, make sure you select your Baudrate to 115200 under Comms Tab.
