Thanks Steve! The key question is whether it’s safe for a user to swap out those parts, and whether the likelihood of a typical user damaging the machine is high enough that we can’t risk it. Unfortunately we can’t depend on everyone being as capable as folks like you. : )
Also just checking to be sure you aren’t buying something you’ll regret later - you’re aware that Glowforge can’t cut metal and that some metals require Cermark or similar spray to engrave, right?
