Hi,
My laser dropped powers in the middle of the cutting program. It was cutting nicely with 30% power thru 3 mm thick wood, but middle of the program the path became uncontinuous and weak. First I replaced new tube, Cloudray 50W, and it helped a bit. The path is continuous, but still there's no "boost" in the laser beam after focusing lens. Today I changed new lens, but the result is same, weak.
Earlier the cutter fired vector graving nicely with 0,1% power, but now the result is about the same with 10% power. So it seems with quick ratio, that power is 100 times less than earlier. I have tested the MYJG50W power unit test button, and according to my knowledge, it works ok, thus red light emits when test button is pressed. STILL, I'am wondering, could the power unit be the faulty for weak cutting power?
Thank You all BeforeHands!
