Mini 2 LCD freeze
Closed, ResolvedPublic


When starting a print with the Mini 2 through the SD card reader, the LCD will freeze after a few minutes into the print. Also looses all functionality to the LCD as well, so you can't do anything until you restart the printer. Happens on (at least) both 9.10 and 9.11.

@karrad I haven't been able to test it yet, but I'll get on it.

@karrad It looks all good here now. No freezing through a 2 hour print. I'll also test this on the Micro and let you know how that goes.

@nathan Great to hear, let us know how it goes!

@marcio It looks like this commit was to u8glib and LB conditionals, it should be applied to all LCD machines correct?

@karrad: Yes, I applied it to all machines with LCD.

@karrad Looks like the Micro is good too. Not as far into a print (going to be gone before this one finishes), but its working as it should.

@nathan Great, thanks for verifying!

We encountered something similar to this on the Mini 2 AS at IMTS. @MikeR should be able to pull the unit from the show pallet once it's delivered. The SDcard should still be in the GLCD.

@Orias do you have an idea when those machines will get back to AM?

Not offhand, I'd imagine by the end of next week.

LCD screen froze at 38%, print finished and LCD unfroze. Mini 2 running

Clarification: print was running through USB

Similar issue here, but earlier in a print. Just happened today. LCD unfroze once the print completed.

Still freezing on Mini 2 Micro - USB printing - LCD unfroze upon print abort (didn't stick to bed)

I am also seeing screen freezing with printing from an SD card.

I am using on a mini 2 with a Hardened Steel Plus toolhead, connected via USB to Cura directly. My LCD froze, I restarted the machine to get use of it back.

Has anyone using a mini seen this recently? Hanna hasn't had any LCD freezes since she started working with 2 minis that have newer FW. (about 3/4 weeks of daily printing)

@anolen I have not seen any other reports, we can go ahead and close this down. If another instance occurs, please open a new ticket.
