Per @Dan’s request…
Wednesday night I ran a project on a piece of maple hardwood- I happen to be watching closely and videoing while marveling at the new proofgrade engrave settings.
The engrave itself went more or less as expected, but as soon as it started the final cutting step, I noticed in addition to the usual bright white light where the laser hit the material, there was also a red, clearly laser, dot.
I think some people think I’m seeing things or some weird artifacting…
This image is :34 in the attached video, you can see the red-dot overhangs the edge and hits the floor of the engrave, behavior that can only occur if the light is coming from above, not sideways or some optical weirdness.
Nothing else seems to be out of the ordinary, other than some occasional weirdness with calibration last weekend but sounds like everyone else has had a touch of that.
Haven’t run anything since then, but will do some more experiments tonight.
