I recently received my Glowforge and I have a few concerns. My wife recently wanted to cut a piece of leather she purchased at a fabric store. Upon trying to cut it, the Glowforge software kindly told her that no Proofgrade material was detected and that proceeding would void the warranty.
I have a few problems with this.
When we purchased the Glowforge, Proofgrade materials did not exist. To my knowledge, none of the promotional videos displayed usage with Proofgrade materials. I also recall being told that Inventables carries materials we can use with the Glowforge. The Glowforge was sold under the implication that we could cut materials purpose-made for laser cutting. It’s now apparent that we’ve been vendor-locked to purchasing a more expensive product with a more limited range of materials available.
In addition, there are images in the catalog that clearly do not use any currently available Proofgrade materials (colored leather, etc). I understand that there are possibly many materials that can cause problems for the Glowforge. However, we should at least be given a list of available third-party materials that have been tested by Glowforge staff, which do not void the warranty. It’s clear that they have been testing the Glowforge on more than just Proofgrade materials (chocolate, sushi wraps, cardboard, etc).
I’m excited by all the possibilities of the Glowforge, except it seems that those possibilities are much more limited than advertised.
Given this limitation, I would not have purchased the Glowforge, and certainly cannot recommend anyone else to do so.
P.S. I don’t have a problem with Proofgrade materials themselves. I would generally opt to purchase them instead of a comparable product. However, the catalog of available Proofgrade materials is rather limited.
