Of course, we are talking about the Glowforge, which will have real time continuous autofocus, which in theory should make minor warping a non-issue in practice.
other than when you absolutely need a perfectly perpendicular edge of course.

You’re already out of luck with that. Because of the converging/diverging beam thing, lasers can’t guarantee a perpendicular edge anyway, just a consistent angle.

You should probably ask for the hygrometer logs from their office building as well.

You misunderstand the reason for my request.
Did you give a reason?
You just want them to tell you how much warping they’ve seen, regardless of the conditions of their office?
No, stay tuned.
Yes.
It’s hard to understand that which has not been communicated.
I should have said that because you don’t know why I am asking for that information, you have no basis for your snarky comment.
While I’m in info-collecting mode, does anyone have an estimate of the vertical distance between the top of the honeycomb bed and the lens that is in the lid (not the one in the moving head)?
To the best of my ability to measure because it’s a challenge to find a reference point and put a measuring device in the Glowforge and then close the lid without my hand being in the way. Brother attempted it:
4 and 7/8 to surface of the lens in the lid camera.

The hygrometer logs would tell you what their humidity levels are. I’m sure they’re higher than someone in Phoenix or even my house - we’re in the winter heating season an my house starts getting into the 30-40% humidity zone. During August it’ll be twice that. Wood warps differently here summer vs winter.
What magnets do you have/use? Size?
I’ve been looking into getting some time have at ready. Thanks in advance!

These first ones are my “go to” magnets. They’re fine for 1/8" Baltic Birch and cardboard or paper that might get blown by the air assist.

These are bigger but still thin enough to fit under the head when it’s focused properly so they’re for larger stock where I only want to use 1 magnet vs a couple of the smaller ones spaced out a bit.

These are a great set as well. Thin and widespread force. Wicked strong.

Just curious if anyone has an idea. I know the honeycomb grate is built specifically to be magnetic, but is there anything in the glowforge that particularly strong magnets could affect if they were placed on the bed. I’m asking because a while back (several years now) I bought some rare earth magnets that are ridiculously strong. They are about 1/2 in wide and an inch tall and if you get your finger between two of them you will regret it 
they would be great as stops because nothing will easily move them, but I wouldn’t want their magnetic field interfering with any of the “magic” going on in my glowforge.

The GF has some electronics/cables sensors on the moving head…and if you move those through a strong magnetic field, electricity is induced in the copper wires and flows. So, is it enough to disrupt anything? - Rich
that was my question 
I bought these to hold paper on the back of a 1/4 inch plexiglass marker board (one magnet on each side “clipping” the background paper to the board. That way I could put any kind of background behind what I was writing that I wanted to. Worked great, but even through 1/4" plexi the pull was so strong it took a good amount of force to pull them apart, and even more to keep them form then snapping to the metal frame!
