My Ender 3 Max Neo Stops Extruding Filament Mid-Print

Well, the motors were still running, it's more like the filament got pulled back far enough that it wasn't working anymore. My temperature is a tad more swingy then before, but stays withing a couple degrees Fahrenheit of what I set it to during the print. I used older filament for a while, then tried some new stuff that hadn't been exposed to air. I printed it at normal speed for most prints (this happens every time) but I did try changing the speed, both to slower, and even quicker speeds. I'm not sure if I understand your final question, I don't believe I changed any setting though, my printer worked before.

Sorry if I was unclear at any point- I'm really tired rn, but basically those are the details. What are your thoughts?

@jobcavanaugh Okay, thats a tough one. But I have a couple more questions. What kind of slicer do you use (Bambu Studio/ Cura/ Slicer/ Prusaslicer)? What Brand of filament did you try? And what was the reason for changing the hotend back then? Is it the original one or an aftermarket hotend?

Check if the Bowden tube is connected properly. Its the tube for the filament which may have been loosend during repair or just from long use. There should be little to no play on both the Extruder Motor side and the coldend side. Try pushing it in more - you might get lucky there.

Some cheaper filaments can vary in diameter, which may cause problems. If you stick with brand names, you should be fine.

There is a possibility that the filament is getting pulled back too far. Thats a setting in the Slicer. It´s called "retraction" or "extruder retraction". Should be a couple of milimeters.

Check your extruder thightnes. It should grab the filament and push it with pressure.
