Hey all, I plan on cutting a lot of 1/2" and 1/4" plywood, simple rectangles all the way through. I was told by several people that it’s best to use a vacuum table to hold down thin plywood, is that the case for any of you that cut thin plywood? My concern is slightly warped plywood that could be cupped. Is there any other reliable way to handle it? I know a lot of people prefer cutting the thinner plywood with lasers, but I don’t have one.
I’m new to CNC routers, my Shapeoko 5 Pro hasn’t even arrived yet. Thanks for any help or tips!
Regarding the slightly cupped plywood, a benefit of vacuum workholding is the even pressure. You might see it pull down and effectively “flatten out” your plywood which might be nice.
Granted, it might re-cup after cutting
My approach on that, since they’re so small would be to set up work holding from the left/right edges and cut the front/back edges first, then re-clamp from the front/back and then cut the sides free — two operations, but it should let you maximize material.
