I love I found your videos. You have been teaching me a lot. I look forward to watching them all. .I do have a question. I am having issues with my laser head burning upper columnating lens. Should i consider cleaning the fiber wire head. I just had the Bodor technician out and rebuilt the laser head, and after 4 months, it happened again.ill gladly pay you for your input
Do you often replace the upper protective lens? If it is, the reason could be the dust in when you replace the lens. If you never change the upper protective lens, and there is a white dot in the center of collimating lens, probably it is time to check the lens for fiber laser.
