Hi @alizabeth33,
Thank you for signing up to be considered for the Pro Passthrough beta! We’ll let initial testers know by email when we’ve turned on the software for them. For now, if you’d like to stay up to date on the beta, please keep an eye on the thread in our community forum: Pro Passthrough Beta Application
Unfortunately, I don’t have more information on how the team is selecting which units to start with.
I’m going to close this thread, but please feel free to reach out to support@glowforge.com if you have any additional questions.
