Filament stopped feeding- and the sensor WORKED!

For the first time in the 3+ months I have been using my MK3, the filament sensor actually detected that the filament was not feeding mid-print (not a run-out, an actual lack of filament movement)- this really surprised me!

I was printing with a new filament I have not yet used (Inland PETG, Opaque Green). I was printing at 245, just under the max of the 230-250 range. Half-way into the print, I heard the extruder struggling a bit and starting to click- so I went over to the printer to bump the extruder temperature up. As I did, it started clicking quite a lot, and then the printer stopped movement, paused for a few seconds, and moved over to the right front corner and asked to retract the filament (this is the same procedure I have seen when I put in a color change). I proceeded with the retract and reload, and then the print resumed right where it had left off. It worked wonderfully. I had bumped the temperature up to 255, and the print resumed and finished just fine with zero extruder clicking.

I have had some clicking with some finicky PLAs, but never a full stop like happened here.... the filament sensor absolutely did its job in this case and saved my print. Whew!!

Re: Filament stopped feeding- and the sensor WORKED!

I upgraded to the official 3.2.0 release last night, and mine has successfully caught filament not moving about 4 times. I keep forgetting that my end G-Code unloads the filament, so I start a new print and it can't print. It stops right after the initial priming line and asks to reload the filament.

Only once have I had a jam since the new firmware, and it recognized the jam within a minute.
