Extruding in blobs

Hi,

I have not changed anything but now I am not getting proper extrusion. The plastic coming out in blobs so that the printhead hits these on the second layer and throws it off alignment.

Doing a manual extrusion it comes out alternately in a stream then sideways in a big blob.

Not sure what has changed?

Have you cleaned your cores with a hot pull or atomic pull? The curling sounds like gunk in the core.

Also, what material? Is it hydroscopic?

Actually I think I am being misled and the problem is simply the bed is slightly too high for the first layer. This gives the impression of blobs but might be because the bed is blocking the nozzle too much. I will try adjusting.

oh...I had assumed by "Manual Extrusion" that you were using a "Move function" to force the material through while not printing.

My mistake...sorry
