Sometimes it goes too fast and I forget to check the thickness of the plywood. Especially 3mm Plywood is available in different thicknesses around 3mm. If I remember, I measure with a caliper and correct the drawing, if I don’t, there is only a 25% chance that I have the right material for the task in the machine.
So it was good that I had to check my settings for acrylic 3mm before I could confidently pass this information on to another thread here in the forum. I made a small tool with the 4 typical measurements that I get plywood delivered with. To decorate a bit, I have put some different radii on the corners. When I set my kerf to 0.075mm, it fits fairly precisely, of course it has to be adjusted as needed.
Can’t do clear acrylic on my diode laser, but I found the red sheets I use for eye protection can be cut. I have some 1.66mm ply too. Thanks for the file!
I recommend that it should be as thick material as your machine can handle so that the gauge remains “shape stable”. Two times 1.66 Plywood will be fine, make a few centering aid holes and glue the parts together.
