Random characters on screen
Equipment: MK3S+, bought new January 2022, 352 print hours. Stock firmware. Revo upgrade since 10/2022
Scene:
I took a print off the bed and preheated it to start another print. Random strings of characters appeared. I restarted the printer. Normal text but when I go into a menu it's random characters again. Pressing the knob a few times sometimes clears it.

Have not seen this myself. Check cable connections and make sure that they are seated properly. Unplug and replug in is the best option. If this doesn't work, reflash the firmware. Maybe it got corrupted somehow.

Can also happen when there's a discharge of static electricity when you touch the printer.
