Discrepancy Between Reported Print Completion and Actual Progress on Prusa MK4
During a 3D print job, I made several adjustments to the print speed using the "Tune" function on the printer's display. I decreased the print speed from 100% to 95%, then to 90%, and finally to 80%. After making these changes, I did not closely monitor the printer and left it to complete the print.
To my surprise, the printer eventually reported that the print was 100% complete and moved the print head to the park position. However, upon inspection, I discovered that the printed object was only around 60% finished.
I'm unsure about what could have caused this discrepancy between the reported completion and the actual progress of the print. I suspect it may be related to the adjustments I made to the print speed during the process.
Could you please help me understand what might have gone wrong in this situation?

So you came to a finished incomplete print? That sounds more like a nozzle clogged or filament snapped or got caught somewhere so it was not actually printing for some time, doing all the moves but depositing no plastic.

It was clogged. First clogged nozzle for me. I focused only on my changed printing speed parameter.
How do I prevent the nozzle from clogging the next time?
I reduced the print speed to 80%, so I quess the 215°C hotend heat could creep up more the nozzle tube and melt the filament at/before the "heat break" (copper ring)?
So should I therefore reduce the hotend temperature as well to compensate for the reduced extrusion?
