Has anyone figured out how to identify "Generations" with the X1's

As the title says.

Has anyone figured out how to distinguish the different generations, batches, lots of printers yet?

IIRC the Gen 1 as in the kickstarter printers had the aux cooling fan held on by ?glue? and then gen 2 which was the preorder lot was screws.

If we could identify each generation then it might help us as a community to attribute some of the issues (warped bed, motherboard fan failure, print fails after a FW update, ect…).

Same with AMS, we already have 4 iterations or more.

Wow, 4. I knew of 2 based on the outer shell.

Resurrecting this thread because I really would like to see this populated with identifiers of changes between models.

One user got a second and noticed different base feet on his X1.

Not sure if this counts but the only difference I can see so far of my two printers is a Laser Caution Label on the bottom of the printer…
