top layer has nozzle imprints

Hi all,

So I'm printing some simpler items now. What I notice is that the top layer doesn't have a nice smooth finish. It seems to be leaving some nozzle imprints on some parts, or small bubbles.

I had the nozzle lift 1mm every movement, but have reduced that to 0mm.

An uncalibrated extruder can cause overextrusion which looks very similar to what's going on in the picture.

Alternatively, if you're using Slic3r 1.2.9, it has an issue with setting correct extrusion rate in gap fill, which could also cause the problem. Try downgrading to Slic3r 1.1.7 (stable) or 1.2.6 (experimental) and see if that helps.

UNBELIEVABLE!

I printed this other support calibration test pattern, the support just snapped off with very little effort.
The top of the print is also way better (actually finished).

Thanks so much for pointing out this item!
