well… they never stopped anyone from discussing non-proofgrade products/materials, just the settings that were used. They have even suggested other sources for laser-safe materials.
I mean, it would be sweet if they were doing in-house testing of a variety of laserable products from well-stocked vendors, giving us suggested initial settings, partnering with said vendors to give us those products at a discount, etc. But I understand why they don’t offer tech assistance for products that they don’t sell.
From a vertical-integration standpoint, I would have thought to see more ads with Catalog Designs made on Proofgrade, but the Design Catalog has not exactly kept up with the range and breadth of the designs/uses that the community has come up with.
