Why Can't The Laser Marking Machine Find A Valid LMC1 Device?

The laser marking machine cannot find a valid LMC1 device. There may be several reasons:

1. Connection problem: There may be a problem with the connection between the marking machine and the computer. At this time, you need to check whether the connection cable between the marking machine and the computer is plugged in properly, whether the connection cable is damaged, whether the connection port is loose, etc.
2. Driver loss: The driver of the control card may be lost, causing the computer to be unable to recognize the device. At this time, you need to reinstall or update the driver.
3. Power supply problem: If the control card does not receive a stable power supply, it may also cause the device to fail to work properly. At this time, you need to check whether the power supply is normal.
4. Control card failure: The control card itself may fail, causing the laser marking machine to be unable to find a valid LMC1 device. At this time, you need to replace the control card or seek help from professional maintenance personnel.
In short, solving this problem requires investigation and repair from multiple aspects. You can check one by one according to the above reasons and take corresponding measures to solve it. If you have more questions, please contact Fly Laser.
