Converted to Arduino pin numbering There are two Arduino IDE extensions that are compatible with this board and with the mainstream Marlin software. All have been used with Arduino 1.6.12

Teensyduino - http://www.pjrc.com/teensy/teensyduino.html Select Teensy++ 2.0 in Arduino IDE from the 'Tools > Board' menu

Installation instructions are at the above URL. Don't bother loading the libraries - they are not used with the Marlin software.

Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support This is basically Teensyduino but with a bootloader that can handle image sizes larger than 64K.

Installation:

  1. Go to the above URL, click on the "Clone or Download" button and then click on "Download ZIP" button.
  2. Unzip the file, find the "printrboard" directory and then copy it to the hardware directory in Arduino. The Arduino hardware directory will probably be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
  3. Restart Arduino.
  4. Select "Printrboard" from the 'Tools > Board' menu.

Teensyduino is the most popular option. Printrboard is used if your board doesn't have the Teensyduino bootloader on it. To burn the bootloader that comes with Printrboard:

  1. Connect your programmer to the board.
  2. In the Arduino IDE select "Printrboard" and then select the programmer.
  3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
  4. The programmer is no longer needed. Remove it. SILKSCREEN ERROR

The silkscreen for the endstops do NOT match the schematic. The silkscreen SHOULD read (from left to right) X-STOP, Y-STOP, Z-STOP & E-STOP. The silkscreen actually reads E-STOP, X-STOP, Y-STOP & Z-STOP.

The pin assignments in this file match the silkscreen.
