Things are still extremely slow going, being that I've been busy. Also, still several more hundreds of dollars to sink into this project, but i'm trying to finish some others first.
However, I thought i'd post this. I've had it designed for months now and thought it's not doing any good sitting on my HDD, so I decided to post this to maybe inspire some others trying to create laser aiming and focusing rigs for their cutters.
The concept is simple and actually Bart came up with it...
Two laser pointers that are mounted on the laser carriage that can be adjusted to a known angle. I also added a y-plane adjust, in case the pointers are not exactly inline with the cutting beam.
You first have to burn a point on to the material you want to cut then adjust the two lasers on to the point.
After the initial setup the laser pointers then show where the cutting laser will hit and if the cutting laser is in focus via merged and un-merged pointers.
