I searched and cannot find the answer to this issue so I decided to post here and give it a try.
I have a 60W Chinese laser, Ruida, and it has a RDC6442S-B (EC). My laser is two years old and stopped firing in the middle of an engraving job. Now I have no red pointer light and pulse does not work. LED 15 is solid red and 14 blinks. I have no loose wires anywhere and water flows properly.
Please let me know what other information is needed for me to get operational again.
Thanks in advance!
