Filament Stops Feeding During Prints

When printing a model that requires more than hour to print, the filament will stop feeding through the nozzle midway through the print. We have cleaned the nozzle and performed resets.

P1S
eSun and/or Sunlu filament

like it just keeps printing midair?

Is it happening at the same layer every time?

No, it just stops printing

What error code does it give you

No error code, just stops printing

the last one that was printed stopped on 44th layer out of 160, but it varies on each print

Is your filament spool possibly crossing over?

What does it say as far as print status on the touchpad on the printer?
Some of the replies are based on the filament stopping but is that the case or is the printer stopping mid-print. A bunch of folks have been experiencing the latter.

sounds like possible bad microsd card?

we checked the filament spool and it is fine

There is no message on the app or on the screen. I would say that it’s a case of the filament no longer be extruded, but the printer is still printing, just without the filament.

yes it just stops midair and no filiment is coming out

On the home screen on the touchpad, the bottom bar should show progress. It should show a more detailed view in Studio.
This is Studio.
Do you show progress like in left red box and get to 100%?
Does your AMS in right red box show the filament flowing from the AMS slot to the toolhead. In this example I am printing a generic tuquoise colored object. YOUR AMS should reflect which slot by a thicker line in the line from the AMS to the toolhead.
What do you show.? If needed pick some quicky model, slice and print

On TouchPad This I took before print started but is a horizontal progress bar
TouchPad

Is the first pic taken from a P1S? That looks way better than the camera feed on mine.

Yes it is. It’s the frame rate that makes motion look terrible and I just happened to catch it at the right time. Pure luck. When it makes any travel move it’s a blur.

All, thank you so much for your input and ideas. Nothing is working, and it’s irritating, after putting this much money out for what was supposed to be a quality product. I’ll be returning this tomorrow.
