Is this normal?


(John) #1

I can’t seem to my K40 laser to cut properly. I have checked the alignment, changed the mirrors, and the focusing lens. On closer inspection, I see that the discharge end of the laser is discolored and is a blue-green color. Is this normal or am I looking at a replacement.

I have had it a little over a year and use 2 days out of the week for less than 8 hours a day. This is the stock tube that came with the machine,

Thank you for your time and help.

John
