Hey all, I’m still trying to get my sea legs on with my glowforge by trying new things. I used an extension to design a cylindrical living hinge box (I’m new to living hinges), however when cut, it seems so burned and delicate. Attached are pics of the hinge top side (cut side) and bottom side (si…

I’d guess the design is way too intricate. I’ve never cut “living hinges” but had similar issues with really delicate designs.

I agree with @eflyguy , I’ve had this happen before. Is there a way for you to increase the spacing in the extension on the cuts you are making? That should markedly help… plus that’s a pretty slow speed…

here is a screenshot of the extension… I can change the cone height, and the diameter of the small circle and large circle, but it doesn’t let me change the spacing of the LH… I guess I can go in and do it manually (which seems tedious, but easier than creating the whole thing from scratch). [Scre…

Thinking outside the box here - set all dimensions to 1/2 (1.5 thick, 35 small/35.5 large) then double the size of the resulting design.

Thanks @eflyguy I’ll try that. In fact, I might even go down to 1/4 scale… It’s actually a conical box maker, but I wanted it more cylindrical then conical and the size doesn’t have to be exact (for now), just trying to get my feet wet (and jeez I hate wasting wood like this, its getting expensive!) …

125 speed is way too slow for 1/8" birch plywood. That’s the Proofgrade cut speed for 1/4" MDF on a GF Basic, which is more than twice as thick and dense. This slow cut speed is burning up your material. Baltic birch plywood often has glue spots and patches in the inner ply that you won’t be ab…

In general, to avoid scorching you want to run fast. So instead of slowing your cut down to get through all those last bits run a second pass. And yes, BB can unfortunately be inconsistent in spots.
