Many people have encountered the problem of 'unable to find encryption dog software will work in demonstration mode' and 'laser marking machine cannot find encryption dog'. How did this problem occur and why did it occur? Let's continue to take a look at the solutions after this problem occurs.

The cause of this problem is that the laser marking machine is not connected to our industrial computer, which means that the laser marking machine software is offline. The reason is definitely not that it suddenly becomes like this. We can troubleshoot the problem one by one and find a solution.

1. If the vertical line connecting the marking machine is loose or damaged, we can unplug and plug in the USB data cable at the back of the marking machine, which is the interface of our ordinary home printer, the square interface data cable, and then unplug and plug in the USB interface on our computer again, and then re-enter the laser marking machine software to solve the problem.

2. The power supply of the control card is abnormal. This issue is caused by a damaged power supply of our marking machine, which is powered by 5 volts and 3 amps. We can use a multimeter to test the positive and negative poles of this 5 volts and 3 amps power supply to see if the output voltage is 5 volts and 3 amps. If it is not, it means that this power supply is damaged, and we only need to ｒｅｐｌａｃｅ it.

3. The laser control card is damaged, which is also a common problem. There are many pirated control cards on our market, and they may also be damaged after several months of use. We can rule out whether the USB interface is damaged, then rule out whether the power supply is damaged, and check if the control card's light is on. If it is damaged, we recommend replacing the control card.

4. In many cases, the damage to the software and drivers of the laser marking machine may result in the reinstallation of the system or the ｕｐｄａｔｅ of other drivers or software on the industrial computer of our marking machine, causing the laser marking machine to not connect to the computer. In this case, we only need to ｒｅｐｌａｃｅ the corresponding drivers and software to solve the problem.

The above analysis shows that the solution and problem of the encryption dog software working in demonstration mode cannot be found. We hope that the problem of the marking machine not being able to connect to the computer is basically the same. This principle is actually to connect our industrial computer to the control card of the marking machine, and then connect our laser data and mirror data to our control card. If there is an abnormality in the control card, it will also cause the movement of our laser and mirror to be abnormal.

When using a laser control card, it is necessary to use a genuine one to ensure that we do not encounter bigger problems in our daily work and that it does not affect our workflow and progress.
