Well the unthinkable happened. My K40 fouled up. I’m not sure what happened but my working theory is that my accidentally dropping the laser tube door really hard caused a retainer to fall out, which in turn released spring tension on mirror #1.

Retainer and Spring on Mirror Assembly
Laser beams were firing all over the place. The dreaded realization came to me that I had to do a mirror alignment on the K40.
Okay, I removed the #1 mirror and reinstalled the spring and retainer and remounted it.
To my surprise I got it back real close to where it was just by using a sharpie to locate orientation.
