Laser beam Target to fit a Universal M300 laser to align the laser beam.

The Laser I have is an old > 10 years used laser cutter The problem seen was push fit bearing holes were not straight so bearings did not fit vertical to the board surface see pic of single bearing.

I noticed that the Lense assembly had a secondary counter bore around the laser hole made a target to fit the counter bore to alow laser alignment using the red spot laser / Lid open mode.

Push fit bearings now sit parallel after laser adjustment using the target
