Connect to the Computer #

The control board needs a 12-24V power supply at about 1A, then plug the USB into the computer,

Note: connecting only the USB will result in insufficient current, and the USB device will repeatedly disconnect and eject,

Note that if you use an A4988 module or a 2209, this power input will also supply them and drive the stepper motors, so make sure the power supply is sufficient!!

After plugging in the control board, you can see its serial port number in Device Manager under “My Computer”,

Everyone’s port number is different,

If you can see the port number, it also means your computer can communicate with the control board normally,

Connect the Host Software #

Since GRBL is open-source software, many GRBL host applications can be found on GitHub,

(our role is to make the hardware carrier for that software),

Some applications may connect and work with this control board smoothly, others may not, and this is not the fault of the control board,

This tutorial uses Candle2 as an example; other applications work the same way once you are familiar with them,

candle2: https://github.com/Schildkroet/Candle2

Click Release on the right side to download the compiled, ready-to-run programs for each version,

The version downloaded this time is: https://github.com/Schildkroet/Candle2/releases/download/V2.4/Candle2.4_5.12.2.zip

After opening the software, protocol must be set to GRBL1.1, Baud must be set to 115200, then select the serial port number of your control board and click connect,
