I just pulled my LM2 off the shelf of may garage (it was covered) and did a deep cleaning of it. I am having troubles getting it to work, and it worked fine 9 months ago. Here are some pictures of what I get when I do a material test I bought off Etsy a year ago. I have tried all I know and can not get it to work, though I did go through chemo and have bad chemo brain. Is my laser bad or is there something I am not doing right?
