Is this under extrusion?

Recommended Posts

This happens from time to time. it mostly happens on the first layer after some infill.

Is this under extrusion? if so, what can I do to helt it? if not, what is it then?

The outher (and inner) surface looks good, there are no string, no deposits from oozing, I don't think there are any problems other than this, and it bothers me.

I had one time where the printer was printing in the air, this was due to a knot on the filament, but can this still course problems? because of the knot, the drive wheel was dirty, so I cleaned it, thus there should be no problem there.

The printer have (only) been running for a week, if that have anything to say..

Hi,

this doesn't look like under extrusion to me but rather the first "bottom" layer after some infill. If the photo depicts the finished object, then it is a huge problem. But if it is just printing one layer and then another few over that one, then it should be fine.

However it could be that the nozzle is a bit clogged. Check out this guide about the atomic method:
