Stringy Infill

[grey_nold 0]

Has anyone come across this at all? I haven't been able to find any other posts about behaviour like this. The shell is printing great but everytime it tries to do the infill, it comes out looking like the picture.

I jut switched over from ABS to PLA and had a hell of a time unclogging it, but eventually got it extruding nicely. If it wasn't for the shell, I would think there is a clog. I have this printing under the default normal settings.

Any help would be appreciated. Thanks!

Um - "never use default settings"??

I don't know what they are but I believe it does infill at a faster speed.  You are probably already printing close to the limit for your given layer height and temperature and the infill speed is probably much faster.  I think defaults are 50mm for shell and 80mm for infill.

Here are top recommended speeds for .2mm layers (twice as fast for .1mm layers):

20mm/sec at 200C

30mm/sec at 210C

40mm/sec at 225C

50mm/sec at 240C

The printer can do double these speeds but with huge difficulty and usually with a loss in part quality due to underextrusion.

Thanks for the reply. I didn't see this till just now. i will try those out and let you know how I go. It's weird as this problem has never popped up until just now but thanks for the input.
