Have to agree with you Jason. That is usually what Russ does.

Simon- that sounds like the ideal product for a pin board- I have spent 10 minutes googling both fireboard and cement-bound chipboard with very limited success. I wonder if a brand name might help me or if anyone in N Americas knows of a similar product? Thanks Gene

And Jason, I would do a test with your laser, I anticipate problems. I can't see the power level in your sig right now (in the reply window) but I seem to remember 80watts?

I know you can cut it with a saw but I wonder how it will machine? Wayne has used it but thinks it will crumble when trying to machine. Gene

That is an interesting recommendation, Simon. If you want to cut it intentionally, will a laser cut it about like wood? I am guessing this is similar to what you are using over there in the UK?

My guess is it would cut like "ROCK" - not so swell, but it would probably engrave like granite.

Here is an eps grid of 1/8" holes for 16 x 24 bed.
Spaced 1" apart - 1/2" in from edges.
If others are needed, I will do them for you.
Center the grid on your material.

Thought I would share this. My bed has a sheet of steel can't remember if it was 16 or 18 gauge screwed down. I recently built the pin plate like Russ to sit on top . Mine are 3/8 inch acrylic with 2mm hole space about 25 mm apart. The steel dowels are 44mm long. I am having fire issues as stated here by others I cut mainly at about 32 watts the acrylic is pretty marred and staring to warp even. I been using them for less than 2 weeks and becoming very disappointed by there performance. I didn't think the beams power would be strong enough at that distance. Gene did you ever CNC that aluminum plate you posted that sketch of? How is it working?

If it is cutting 1-1/2" lower than the material, I would think you are using too much power.
Russ' bed does have some cuts in it, but that is due to using too much power, so he cuts back the power to make the cut.
Might also have a bit to do with lens FL and focus point.
