Solved Filament Grinding

I was making a larger print and it was maybe four hours in and then it seemed to stop extruding. By the time I woke up in the morning it was still printing but nothing was extruding. I opened up the hobbed gear area and took the springs off and it was as I expected, the filament was all chewed up. I was printing at 40mm/s at 210 using PLA at .2 layer height with a bed temp of 55. I was previously having an issue with the tightness of the spring screws where it wasn't tight enough which caused the filament to get chewed up so I tightened it up a decent amount and it seemed to do the trick until the mid-print failure. Any tips or advise would be greatly appreciated, thanks!

 

Is your hotend fan running?

 

It's running pretty good. I'm thinking that maybe the cause was that the spring screws were tightened too much?

 

Have you seasoned the hotend and are you using an oiler?

 

I have done neither, I haven't really had an issue with this before. I'll give both a shot.

 

I print PLA at 195. It seems to be the perfect temp that will allow for support and raft material to be removed without issue.

I tried 205-210-220 but is way too hot for PLA and will cause issues such as clogging your hot end or the raft will be very hard to remove, etc.

Check out 3D troubleshooting guides. Search google. It also states PLA should be ran at 195

 

The seasoning and oiler work like a charm, I did both and loosened the spring screws a bit and now its been printing constantly and reliably with excellent quality

 

@mprinz what guide did you use to season your hotend? just curious because I am due a seasoning as well.
