This just started recently. One of my 5 Max’s just keeps going out intermittently; the touch screen stops responding and it pops up a “Machine Startup in Progress” message. It’ll sit for a bit then do it again.
The printer failed after a print completed and just drove itself down hard against the bottom and kept going until I heard the noise and turned it off. That I’ve no idea why either. Had some error in Chinese on the screen. Now it’s doing this boot cycle nonsense.
Haven’t tried to force a firmware update yet, it’s late. (And I have to look up how that’s even done tbh..)
