There is only one main switch for laser engraving machines

I don't know what model your laser machine is, small machines generally should have at least a laser switch and laser test switch in addition to the power switch and ammeter, since there is an ammeter, there should be a current adjustment knob.

The power switch controls the power supply of the machine, the switch is turned on and the machine is electrified, but the laser tube is not working, turn on the laser switch and press the laser test switch, the laser works, at this time, adjust the current adjustment knob to see that the current indicator meter pointer changes the value due to the adjustment of the knob. Put a wooden board or a thicker cardboard under the laser head to see the wood board carved out different shades of points due to different laser currents, so that your machine is no problem, connect the machine and the computer with a data cable, and use the software that comes with the machine to do what you want to engrave.

As for the water you said is used for the cooling of the laser tube, there is a hose at each end of the laser tube, and the water pump can be connected to the water inlet at one end to start the power supply.

That's it for thousands of dollars. Don't be too ambitious. There's not even an emergency stop switch, let alone an operator panel. It's going to get there. All the actions of the equipment are all controlled by the program, and it is okay to engrave a chapter or something, don't expect to do more.

I have a love family of 8800 yuan laser engraving** Now only buy 4800 yuan Do you want it.

Maybe it's cheaper, it may be a copycat.

Each engraving machine must have circulating water.

Hello landlord.

1. The control card of the laser engraving machine generally refers to the hardware part of the machine, and the control card has many card slots and line connections.

2. The switch mentioned by the landlord should refer to the external switch of the LCD control panel, which is linked to the control card and the motherboard. The two are not the same.

No, it should be said that it is the software of the engraving machine to control the coordination and the operation of the engraving machine.

Hello, your machine is miniature, right, the system is grindstone? As you mentioned, I feel that there are two reasons, number one. Static electricity interference, try to connect the machine to the ground wire, and secondly, it is the problem of the motherboard. The board is very easy to dismantle, you can remove it and return to repair it -- Beijing Yiming Laser.

1. Press the test button on the operation panel to observe the status of the ammeter: No current: check whether the laser power supply is connected, whether the high-voltage line is loose or falling off, and whether the signal line is loose; There is current: check whether the lens is broken and whether the optical path is seriously offset;

2. Check whether the water circulation system is normal: No water: check whether the pump is damaged or not electrified; Water connection: check whether the water inlet and outlet are reversed or the water pipe is broken;

3. It can shoot at a point, can self-check, and the sent data does not glow (check whether the computer settings are correct).

Looking at this situation, there is a high possibility of problems with the main board of the machine.

Why don't you ask the after-sales service of the equipment? Is there a problem with the board?

How's it going now?
