Printer thinks it's done but it isn't

[alathIN]

Still having the same problem. The printer quits before it's done.

There is something wrong with the feeding/extruding. I realized what the printer is doing is "going through the motions" of finishing the job, but not actually laying down any plastic.
I thought I might be having a clogged nozzle problem so I changed the nozzle, then completely replaced the hot end.
Then I realized that I was seeing slippage from the feeder wheel, so I replaced that (the teeth were pretty worn).

My last failed print, the feeder wheel had chewed its way through the filament so the length of filament in the tube was effectively broken off from the filament on the reel.

I'm currently set to a feed rate of 45mm/s with a .4 nozzle which should be OK? Also, if I'm trying to feed too fast, I don't understand why it would lay down the first several layers well then suddenly start chewing through the filament halfway through the job

Check the way the filament feeds off the reel for any sign that the filament is trapped under another winding causing the filament to stop feeding from the reel.

It sounds like you've done a thorough investigation into the issue with your printer. From what you've described, it seems like the problem may indeed be related to the feeding/extruding mechanism rather than the software or file itself. The fact that the printer appears to be "going through the motions" without actually laying down plastic suggests there might be issues with filament feeding or extrusion. Your troubleshooting steps, such as replacing the nozzle, hot end, and feeder wheel, are logical responses to this observation.Since you've already addressed potential nozzle clogs and replaced worn components, it might be worth revisiting the filament path to ensure it's feeding smoothly without any obstructions or tension issues. Additionally, considering adjusting the feed rate or temperature settings could help troubleshoot further.Keep us posted on your progress with the Solidworks model and any further troubleshooting steps you take. Hopefully, you'll find a solution soon!
