I took some measurements using 3mm glass, then switched to 4mm and remeasured.
Using 3mm glass, the centre of the bed was 0.175mm higher than the average of the corners. Using 4mm glass, the centre is 0.075mm higher than the average of the corners.
This is a useful improvement. I used the same 9mm photo frame clips, so the clamping force will be a little higher using 4mm glass. I currently have 3.3mm hardboard under the glass for the clips to lock into, so I'll try using something thinner such as a piece of copper-clad board next.

ive just had a little play around with the standard bed file in the master directory.
Ive never done anything like this before so what do you think?
What format does it need to be for a lasercutter to use it?

...I only need cut to size and drill a few holes before I can try it out. It could be simply taped to the MDF for first tests...

If so how good is it and do you recommend?

I got some quotes but it wasn't anything I would spend.
Made out of 3mm Alu, £250, £200 & £50
So I have moved the aluminium heat spreader down on top of the mdf bed. its better than before but stil not perfect as it still rocks on the rib.

But also look at PaulHam's post [forums.reprap.org] where he provides a good dimensioned triangular bed similar to DC42s picture.Quote

I would try a new bed construction aswell. Therefor I'm looking for the files of the original lasercut parts. Any idea where they hide?

There is the y-rib and the y-cross-rib - but the top?

My proposal is just for a level stable bed (with removable glass (point #4)). You can use Kapton tape, pipe cement or just plane glass which ever you choose. I don't seem to have any problems with my original Kapton taped glass so have stayed with that.Quote

Hmmmm I print on glass, and the only way I can get it to stick is to remove the glass and wash it with washing up
liquid, air dry, then mount.... Also I've found that removing the prints is easy... I put print and glass under the cold tap, and the print float off..
