Does anyone have any idea why my laser beam is coming out like this? This occurs straight from the tube before the 1st mirror and throughout the whole path.
I've drained the tube and cleaned it I thought. Had some algae buildup. Pieces of crud was floating around. Could some of that crud be blocking the mirror or something?
I was using it fine one day then all of a sudden a drop in power and was ineffective in cutting anything.
I've realigned the setup a couple of times. I'm sure it's lined, but the beam itself isn't solid. It's like whats in the picture.
Any assistance would be greatly appreciated.
