    This article applies to:

    D1 and D1 Pro with all laser modules.

     

    Issue Description

    If the XCS software prompts that "the device has been disconnected" while the machine is running and the main board power indicator is blinking, refer to this document for troubleshooting.

    You will also see a blink of the blue indicator at the edge of the motherboard blink, which means it's rebooted.

    This could be the case regardless of the USB or Wi-Fi connection method, as long as any of the power adaptor, the motherboard, and the laser module is faulty. So we will need to check each of them in the following steps.
     

    Note

    If all the steps below don't work, and your machine is a D1 Pro 20W, please contact support@xtool.com and provide the Product Serial Number, laser Code Numer of the laser module, and the label on the power adaptor.

    #1 Check the Laser Module

    1. Unplug the laser module connection cable to disconnect it from the machine.
    2. Try with the same project file and see if this time it can complete the run.
    3. If it can, the laser module could be short-circuited. It needs to be replaced.
    4. If it still can't, please move on to the next step.

    Note: To second confirm if the laser module is short-circuited, do the following:
    1. Get a multimeter and set it to buzzer mode.
    2. Place the needle probes on the GND and PWM pins on the laser module.
    3. If the buzzer goes off, the laser module is short-circuited.

    #2 Check the Connection Cable of the Laser Module

    1. Check if the connection cable is damaged and the copper wire is exposed.
    2. If yes, please replace the connection cable of the laser module.
    Note: When the laser module moves to the frame and its damaged connection cable touches the frame, the laser module may be short-circuited.
     

    #3 Check the Motherboard

    After the laser module is ruled out, check the motherboard.
    1. Check the status of the blue indicator on the board.
    2. If the indicator blinks, the motherboard is faulty. It needs to be replaced.
    3. If the indicator stays solid, move on to the next step.

    #4 Check the Power Adaptor

    After the laser module and motherboard are ruled out, check the power adaptor.
    1. Check if the power adaptor is compatible with the laser module through the link.
    If not, please replace the power adaptor and try again.
    If yes, please move on to the next step.
    1. Check the status of the green indicator on the adaptor.
    2. If the indicator blinks, the adaptor is faulty. It needs to be replaced.
    3. If the indicator stays solid, move on to the next step.

    Note: If the power adaptor is not compatible with the laser module, the machine will be disconnected from the software.
     

    #5 Check the TF Card

    1. Change the connection method from Wi-Fi to USB cable.
    2. Try with the same project file and see if this time it can complete the run.
    If yes, the TF card is faulty and needs to be replaced.
     

    #6 Check the Software Operation

    Note: Please avoid additional operations on XCS during the process, otherwise XCS may be disconnected.
    1. Make sure you don't run Lightburn software when XCS USE Wi-Fi connection.
    2. Make sure you don't change the device on XCS during processing.
    3. Make sure you don't minimize the XCS interface during processing.
    4. Make sure you don't press the buttons on XCS during processing.

     

    #7 Check the USB Cable Connection

    1. Make sure the cable is connected properly at both ends.
    2. Make sure the cable is intact. Try another cable and see if it works.

     

    #8 Check Other Appliance Connection

    We do not recommend that you connect your laser machine and other high-power electrical appliances to the same circuit. It may lead to a large current and unstable power input. If you have already done so, please avoid turning on or off those appliances. If the issue persists, disconnect the high-power appliances and try again.
     

    If None of the Above Works

    If you have followed the instructions above and the issue is still not resolved, please read the article in the link below, collect the troubleshooting steps you have taken, and contact xTool tech support for further advice.
