I had a Chinese Fiber laser unit for 2 years
Model: DTML-F(I)Pulsed Fiber Laser 5w-30w, IPG-YLP Control Card, EZCAD 2.5.3

After initial power-up:
I/o 4 input is on, light fires OK, but Marking is very Weak, I/o 4 input turns off.
the second try to mark Ezcad displays "IPG Laser:System Error!"

I believe either the software is not set up correctly, or the Laser Source is bad.

please guide me what is the problem and how to fix it

What laser source are you using?Is it in warranty?You can contact with your Chinese supplier.
