Used for Rev2.3


have test in machine with Rev2.3 main Board!


A axiz used for mirror y ，T axiz used mirror Z


The more tutorail will update later!


 (Theoretically, it supports 2.0 2.1 2.2, but it has not been tested. If there is a problem under version 2.3, please use the upgrade repair tool to upgrade)

GRBL v1.1 firmware for PiBot Control Board HW Rev 2.3 and above

How To Use:

  1. Download and install latest Arduino. E.g. installed to C:\Program Files (x86)\Arduino

  2. Add PiBot Board Information to the Arduino (Optional).

  • Locate "boards.txt" at Arduino install folder. e.g. C:\Program Files (x86)\Arduino\hardware\arduino\avr
  • Edit "boards.txt", add copy and paste the content at the end of this readme. You will need administrator right for doing so, if installed to the default folder. Recommend to use Notepad++ to do this.
  1. Locate Arduino library folder, e.g. C:\Program Files (x86)\Arduino\libraries
  • Copy "PiBot_GRBL11" folder to library folder, you may need administrator rights.

  1. Start Arduino IDE, from menu, select "Files" -> "Examples" -> "PiBot_GRBL11" -> "PiBotUploader".

  2. (If you done step 2) From menu, select "Tools" -> "Board" -> "PiBot Controller Rev2.x". Then select the correct Port.

  3. (If jump over step 2) From menu, select "Tools" -> "Board" -> "Arduino Mega or Mega 2560". Processor select "ATmega2560". Then select the correct Port.

  4. Read the instructions then click Upload.

NOTE: Before Uploading, ensure external stepper drivers are powered OFF. Switch set to "3D".

ATTACHMENT: Contents to be added to the end of "boards.txt", do not including this line. Copy between (and includes) the hash(#) line.
