My laser is DIY attached to the tool carriage of my CNC machine. To keep from burning up my spoilboard, I took a piece of hard board (1/4" polished MDF - the stuff they make pegboards out of) and used spray adhesive to laminate a thin steel sheet on top. I made some plywood bumpers and attached those to the edges of the board so that by simply pushing it all the way back and to the right, it will perfectly align with the tool head home/zero. I 3d printed a spacer for the X & Y end stops that slip over them to move zero to the laser (it sits slightly forward of the spindle zero.) I use mending plates like this guy and magnets to keep them from sliding around between jobs. This way, I only lay out what I need when I need them - those points are sharp and dangerous so I don't want a bunch of them exposed unnecessarily. The mending plates do work well. I keep a box of them next to the machine for this express purpose.

But how would you clean this if you screw them down? laser cutting plywood is such a mess - my honeycomb looks like a sticky serve stove.

how do i find steel mesh like the one used in the welded bed? cant find the name
@craigmorrisworkshop95146 ай бұрын
the welded mesh is called expanded steel... you can find it at big box stores around chimney/masonry stuff or in the small section of steel that they'll have

The reflexions of the laser will be very bad for your eyes. That's why these honeycomb alu beds have a 2cm height and their honeycomb structure to avoid reflecting light from spreading all around! Be careful with these new gadgets!

I might actually try this- was into construction for almost 20 Years until I got injured and used these for their purpose a lot- the spikes aren't all perfectly the same height, though they're pretty close. If I try this I'll do a light wet sand over the top of the pikes to even them out a bit. Really good idea! Thanks, I'd never have thought of this!

Do not do this with high powered lasers, not only can the laser be partially reflected towards the operator but also the fumes that can be produced from the high temperature laser. The metal he is using has a coating on it that when heated to a burning temperature which a laser can do produces fumes that are carcinogenic and exposure to them can lead to some nasty side affects. But uncoated metals are safe but should use perforated material to avoid reflecting the laser.

not 100% sure what you asking? I need a laser bed for cutting with the ability to use magnets to pin down materials. Hexagon or extruded laser beds are made from aluminum with ferrous metal only on the perimeter and expanded steel is not flat enough. I've never seen a bed for less than $15 that would work this well.

As arminth suggested, I painted mine "engine" black to cut down on reflections. I did not screw them down to a board, as my CO2 laser would make a mess of the wood in the open spaces. It does a good job of resisting the burns on the backside, I used Rustoleum High Heat Ceramic coating spray paint. It is advertised to be resistant to heat damage up to 2,000 degrees. You spray a couple coats, then set the paint by baking in the oven. I also tested to see if my cleaner of choice, LA Awesome would clean them with the paint on- and it does, without harming the paint, so far. Thanks for this solution, I have tried so many other things for a bed, this seems the most useful.

I spray painted them with black bbq paint, burned the paint in in the grill and just lay them on my existing expanded metal sheet bed. No need to screw down. Worked perfect. No burnmarks on the back at all! This is the end of honeycomb! Thanks again! Great video!
