Am I hitting the mirror holder with the laser?

[BenJackson]

While cutting my first reasonably long job I had time to look around during the cut. I noticed a yellowish light on the edge of the first mirror holder. I don't know if I'm just seeing some leakage in the visible spectrum or if maybe that's the beam hitting the mirror retainer. Can anyone else verify if they see something like that?

I think you are seeing the back reflection of the cutting area, ie the bit thats being burnt. I have noticed this in the past.

That makes sense! Thanks.
