Help with diagnosing what is happening
Hello,
I have remained issue free till today. I own a MK3i3 and am on using the 2nd spool of filament that I have not had issue with. Standard 1.75mm Grey PLA.
I was approx 3 hours into a previous print and extrusion stopped. but the printer kept moving on all axis. There was no clicking coming from the extruder.
I removed the nozzle and cleaned it out. Loaded the same filament, proper colour and size. I have now tried to print a different model as pictured below, Now it looks like its underextruding. I have tried to set my Z height thinking maybe I am squishing the filament too much. I made sure the gear on the extruder motor was tight and aligned. I have no idea what is happening? there are globs of filament that show up now on the bed and I found it clinging to the nozzle before it broke off. Ive been at this a few hours now and can't figure out whats happening?? Any help or hints would be appreciated!

Sounds clogged. Did you try a cold pull?

RE:
I can't see from your picture; is there any sign of molten plastic running down the outside of your heat block from above?
Cheerio,

Both @bob-2 & @diem have great suggestions. Try their Idea's first.
I just got off chat with Prusa with a similar issue. In the end was a clogged nozzle. Funny thing is it on a newer Prusa Mini.
Sometimes stuff (Filament and other stuff) plugs the hottend.
Only reason for say this is I could have saved my self hours if I had changed out the Nozzle sooner.
Also don't forget to clean out the hobbed gears with a brush. Here is a link to Prusa's Clogged Nozzle article.

Good luck.
