Ok… I’m just using a bit of logic here. So I’m hoping if someone can help clarify
The following link shows lifetime for some of the proof grade materials.
First, it doesn’t show the life of draft board in the table, while I have read in multiple posts that draft board is just bad to use with the filter. Basically, all my draft boards are high risk for the Glowforge Filter (really disappointed). However, lots of particles from the cuts/engraves do make sense in limiting the life.
Second, the table shows Medium Proofgrade Plywood (1/8?) as 210 while Thick Proofgrade Plywood (1/4") is 1614. That’s a huge difference! I would assume thick would produce more particles in the cuts/engraves compared to Medium.
Third. What is the comparison between Plywood vs Draftboard. I think the table is a mistake or at least I hope it is. I’m hoping actual medium Plywood is performs close to Thick Plywood or better.
