My laser seems to have lost power overnight. I do watch my temps closely and normally don’t run over 20C.
I engrave hardwood blocks and have done several hundred in the past months. The last batch was fine, this batch not so much. I noticed the engraving depth was very poor so I cleaned the mirrors and lens. I also increased the power with no noticeable improvement.
Oddly if I do a test fire I get good penetration, even if I move the material during a test fire I get a fairly deep path.
I do notice the laser beam in the tube seems to be bending at the very end where it would exit, is this normal? Also if I do a 1-2 second test fire the beam is jumping all around and arcing. Is that normal?
I already bought another laser because I need to have one up at all times for my business but I want to try and diagnose this issue. Also the new laser isn’t as nice as my original.
Thanks in advance! PS, when I cleaned the lens I was surprised to see the outside edge was chipped. Just the very edge where I guess it seats when the cone is screwed in. I guess it’s possible this happened between jobs and could be the cause? But again the test fires seem pretty strong even with that issue.
