This is my first post. I have a Chinese Laser Engraver made by Liao Cheng Dongchangfu Division with Laser Equioment Co., LTD. It is in a red cabinet. The email address and web site provided are not active.
The engraver was woking fine and then just stopped outputiing completely. I replaced the power supply, jumped the water flow sensor, cleaned the water pump. It does not pulse or engrave anything. The x,y and z axis work, The lights, and fans work. The cover swithch works. The water flow sensor works. It appears that the tube is not getting a trigger voltage. The laser tube output is 60watts. engraver is a 60watt.
Does anyone have any suggestions?
Thanks DenNOLOA
