¶ Introduction
In certain cases, when troubleshooting Ray faults, we need to use serial port commands to retrieve feedback from the machine to identify the cause of the issue. This article outlines the detailed steps of the entire process for your reference.
¶ Tools Needed
- Ray machine
- USB-A to B cable
- A computer
- Lightburn or other serial port software
¶ Steps By Steps
Below, we’ll use LightBurn as an example to walk through the steps of the entire process. Due to firmware limitations, Luban can’t perform this task, sorry for the inconvenience!
¶ Step 1 Use a USB-A to B cable to connect the machine and the computer.
¶ Step 2 Add your machine to LightBurn.
- Download the profile for your machine.
If you are using a 1.6W or 10W laser module, refer to Adding a 1.6W or 10W laser module in LightBurn to complete the device addition.
- Launch LightBurn, then click Devices in the Laser panel.
- Click Import to import the profile downloaded in Step 1.
- After your machine appears in the Your Device List, which indicates that the import was successful, click OK to close the window.
- Select your machine from the drop-down list beside Devices in the Laser Panel.
¶ Step 3: Connect your machine to LightBurn via the serial port.
-
Make sure you have installed the CH340 driver on your computer. If you haven't, please click the appropriate link below based on the operating system of the computer.
-
Connect the machine and your computer using the provided USB cable, then turn on the machine.
-
Select the displayed serial port from the drop-down list beside Devices in the Laser Panel.
- Once connected successfully, the LightBurn console page will display the machine’s configuration information.
If you can't make a connection, please check the following:
Make sure Luban or other serial port software is not connected to the serial port. If necessary, restart both the machine and the computer, then try again.
The CH340 driver may not be installed, or the wrong COM port may have been selected. In this case, follow this article to troubleshoot. Why does Luban show "The machine is not ready" or "Cannot open this port"?
¶ Step 4 Enter the serial command and wait for the machine's feedback.
Below are a few commonly used serial port commands for troubleshooting:
¶ $Message/Enable=On
-
This command will enable debug mode for the machine. Please note that you need to activate debug mode first before using other serial port commands, as this allows the machine to provide detailed feedback.
-
After entering the command, the machine will respond with "ok" and switch to debug mode.
¶ M1006
This command retrieves the machine’s configuration details and the status of module detection.
Please copy this feedback into a notepad file or send it directly via email when the Snapmaker support team requests it to troubleshoot a specific issue.
¶ M2000 L0
This command retrieves the information and status of the laser module.
Please copy this feedback into a notepad file or send it directly via email when the Snapmaker support team requests it to troubleshoot a specific issue.
