CNC Controller Software Installation

  • How to Install Candle/GRBLControl for Windows
    • GRBLControl/Candle 1.17 (For Windows): Link downloads a .zip file containing a full copy of Candle, the software you can use to run your CNC through your computer. Must unzip entire folder to use.
    • CH341SER Driver (For Windows): If Windows does not do so automatically when you connect your CNC to the computer for the first time, this downloadable file is the Driver which is needed for your computer to be able to communicate with your CNC.
  • How to Install Candle/GRBL Control for Mac (Except for Catalina & Big Sur)
    • Please Note if you Have Mac OS Catalina or later: Unfortunately, due to recent security changes in Catalina and Big Sur, Candle has been unable to run on these systems. At this time there are no fixes, as a lot of the issues are related to how Big Sur changed what software is acceptable, and what is not. Since Candle has not been updated for Mac in some time, it is unfortunately not permitted by the operating system anymore even though it is "Mac Compatible" in every conventional sense of the term.
      What we have been advising Mac Catalina & Big Sur users to do is to migrate to Easel, a browser-based variant of Candle which is also free to use.
    • GRBLControl/Candle 1.17 (For Mac): Zip file containing a full copy of Candle, the software you can use to run your CNC through your computer. You must unzip entire folder to use, instructions on how to install is included in .zip file.
    • CH341SER Driver (For Mac): This driver will not install automatically and must be installed as dictated by instructions included in the .zip which this link will download.

  • Gcode Sample: Originally provided on the USB that came with your CNC, these are pre-made test cuts users can use to try out their machine, or to help troubleshoot issues with other files.

Troubleshooting

  • GRBL Error Code List & Meaning: Whenever something is going wrong with your CNC, GRBL tries it's best to provide you with an error code to help you in diagnosing and resolving the issue you are having.
