Thanks for your interest in Snapmark - we’re excited about it, too!
The Snapmark feature is still in beta, but you can read more about it in the Glowforge Community topic.
There are a lot of factors that go into setting up testers with this experimental feature. The engineering team is determining each step of the rollout. Unfortunately, I can’t affect that process for you. If we do make it available to everyone, or if your machine is chosen for the rollout during the testing phase, you’ll see the Snapmark icon appear in your Workspace. In the mean time, keep an eye on the community for more information.
