[BUG] Display lock when changing run-out filament

[marobi]

Printer type - XL Printer firmware version - 5.1.0 -alpha2

** Print using USB stick

Describe the bug After systems runs out of filament, it tries to retract last piece of filament. However it fails to do so. I manually removed PTFE tube form extruder and pulled out rest of filament (direct extruder side) and reinstalled PTFE tube. This action is displayed. It comes up with a new display text (see uploaded image). However systems does not see filament loading and you can NOT back out of the displayed text. Only solution is to power down/up system. It nicely recover but immediately resumes printed while no filament is loaded. I paused the system and pushed in the new filament and resumed the print. Luckily that worked.

To Reproduce

• run out of filament
• tell system it did not retract filament correctly
• system will display (uploaded image)
• insert new filament (and remove it and reinsert it ...)
• system will NOT recognize insertion and stays stuck in displayed text.
• power down/up system
• system will resume print without loading filament

G-code NA
