Hi everyone!
I picked up a Daquin laser machine with a 40w laser.
I can’t figure out which card it’s on because they purposely deleted the name, I’m attaching photos in case it’s recognisable.
I can’t figure out where to connect the ground wire coming out of the structure.
And, at this point I ask, it is better to change the card and try to customize everything.
Can you recommend me a guide?
this red thread coming out, translated from Chinese, means PE.
But actually, both the machine and the laser are attached to the PE of the socket.
If I turn on it goes to HOME, the power supply has the LED on, but if I press Test nothing happens, the additional air and water outlets work perfectly.
I actually don’t know if I have a good ground connection. for security I add it.
There is no actual control panel, it just has an ON/OFF button and a USB socket. As far as I know, the laser had been in working order and had been standing still for a couple of years now. I’m attaching the manufacturer’s link if it helps. https://www.chinee.net/2021/index.php?catid=10
The voltage on IN is 5V which is the full power setting.
With the IN set at 5VDC when you push the test button on the supply it should fire.
Looks like a bad LPS.
