Laser Bed
Posted: Mon Jul 20, 2020
I built the Further Laser 1200 project and am very happy with it and the additional changes I made to it, but the one thing that I was unhappy with was the bed. Yes it worked but it was a little less than ideal.
Having looked at all the options, tried a few and not liking them someone suggested using self tappers on a perforated sheet. I had done similar on a 300x200 bed but had used "punk spikes". That option was really expensive so the self tappers sounded good.
I started off with a 600 x 1000 x 1mm perforated sheet with 3mm holes of Mild Steel which was lightly sanded with a very coarse paper to rough up the surface. I then screwed in loads of 25mm x 3mm self tappers and the results were just what I wanted. I then bought a second sheet of the same stuff by 600 x 1200 (The bed size) populated that with self tappers at about 40 - 50mm intervals and reclaimed the original as a flat plate for the machine.
The picture below shows the 600 x 1000 being used.
