I have really been enjoying building the 2.x engraver.
I have most everything done, just have a few gremlins to work out.
One of the more major ones is the alignment of the optics. I have it most of the way there, but am having a problem with the second mirror reflecting to the flying optic. Let me see if I can explain the issue.
With the head (flying optic) all the way to the left, the laser lines up perfectly. When I move the head all the way to the right, the laser is about .25-.33" low.
It looks like the mirror is higher than the head so the laser has to be reflected at a downward angle. I have tried to put spacers underneath the laser head mounting plate to raise it, but it does not make enough of a difference.
Anyone have an ideas?
Thanks
