This was brought to my attention recently by sshwarts. I have confirmed it (because I now have my own laser) and I ran into the same minor issue. Surprisingly, I have not had anyone comment either way on the plates so this issue was a surprise to me.
The issue: The gantry bracket no longer holds the Light Object mirrors correctly. The Light Object part must have changed over the years (hole to hole distance grew). I also noticed this on the plate that holds the first mirror.
Easy fix: All I did was drill out another 2 holes towards the front of the laser that extended the slots (use .125"+ drill bit). This allowed the mirror to move forward and alleviate my alignment issues with the carriage. I recommend drilling the holes so the mirror can be held with both screws securely.
If you have any further questions, please ask. I tried to make as much sense as possible without taking off my newly aligned mirrors for a photo.
I have 4 sets left for the 2.X laser. In hand. Changes to the original design will be incorporated after those 4 are sold and the need to make more sets arises.
