@m_raynsford: I posted your blog to our internal “project inspiration” channel and boy, did it get a lot of love from the team at Glowforge. (Good to see you on the board btw; really enjoyed our conversations at Maker Faire!)
@fablab_elpaso: We already do fiducial detection, so it’s definitely workable. Fun fact: the Glowforge logo on the head isn’t just decorative. The camera sees it and uses it to align the head with the lid image. You wouldn’t believe the custom lens needed to focus 20x12 from 6" away, and also stay in focus 1" away…
