Two test runs of the new laser engraver with the 2500mW laser. It seems like the laser is a bit to weak for fast engraving and maybe a more powerful laser would be better. I think I will try a 5500mW laser next.

The downside of a more powerful laser could possibly be, that it could damage the mirrors or heat them up to much. They are just normal chinese galvo mirrors glued onto the galvo shaft - not specialized cutting/engraving laser mirrors.

I also couldn't find special 450nm galvo mirrors anywhere.

The next thing will be aligning everything, to get the dimensions right.

(All axis have endstops so it should be possible by aligning the galvos and mounting the Z endstop on the right position.)
