I have printed a number of channels that are 325mm high over last few weeks without real issues but now after a while the extruder appears to stop working and the print carries on but nothing extrudes. If I pause the print I can extrude normally without touching the extruder, filament or reel.
This is a well used print / 3mf / gcode file.
If I restart , it works ok so I wonder if it is extruder motor overheating. You would expect the print to stop if such a thing happened but I am always suspect of the error catch on K2.
Both Ai and professional settings are enabled.
Anyone had same and found root cause ?

That is one of the many ways my piece of junk fails. I wish there was a store that I bought it from. I would have someone drive my truck past it at 90 mph while throw it at the building.
I had something somewhat similar happen to me just the other night, but on a small print. It would print about 10 layers and then get an extruder abnormality error (unable to extrude fliament) and stop.
I would go into the settings and try extruding and the filament would extrude fine (or it seemed fine at 1st glance) and resume the print, but after a few lines it would happen again with the same error.
I eventually figured out my problem was 2-fold. The first was I noticed while manually extruding the filament was not coming straight out of the nozzle but at a bit of an angle, so I did a cold pull on it and found out a very small piece of metal was stuck in the nozzle. The 2nd issue was when I started a new print I noticed the nozzle tip wiggled slightly. I stopped the print and took the hot end out of the printer and here is where I discovered the 2 small screws that attach the ceramic heater to the heat break(?) had come loose. I tightened them up, reinstalled and now its back to printing perfectly.
I had a similar issue where extruding stops. I normally print with PLA, PLA+ and Hyper PLA. Never had an issue. Recently I put in a spool of Creality PETG. Selected Creality PETG on filament screen. Started printing and after about 15-20 layers, it stopped extruding. This has always printer fine with PLA. What I discovered is the nozzle temp wasn’t high enough for the speed I was printing at, so the nozzle couldn’t melt the PETG fast enough to keep up with the speed and cause the printer to throw a nozzle error. Increasing the nozzle temp by a few degrees resolved this issue. Nozzle temp was initially set at the recommended temp for Creality PETG. The reason why it took it 15-20 layers to stop is because the layers 1-15 were printed at a slow speed by design. It’s when the speed increased that the nozzle couldn’t keep up with the demand. I live in Colorado at 6500ft and have noticed I can not use default bed/hotend temp settings. I normally increase by a few degrees, but forgot to do that when I loaded the PETG spool. duh.
