[Possible underextrusion problem?]

Hey guys, thanks for you replies!

I am using the default PLA temerature settings (210C with 60C bed). And yes, I was using the default print speeds in expert settings.

This makes a lot of sense now, as I upped the layer height of the "fast print" settings to 0.3 from 0.15, effectively doubling the amount of material I'm asking the printer to extrude at the same speed. Top/Bottom thickness was also set at 0.6mm which is only 2 layers so that was probably part of the problem as well.

I was trying to get a fast print, but I guess I got too greedy. I'll try again with a slower speed/ lower layer height, and increasing the top/bottom thickness and see if that solves it. Thanks everyone!

[Possible underextrusion problem?]

Hi everyone!

I've had my Ultimaker 2 for a couple of months now and have been relatively successful in getting good quality prints. However, recently I've been encountering what I believe is an underextrusion problem. I tried a few things including re-leveling the bed and cleaning the nozzle, which seemed to work temporarily but today's print is as bad as ever.

Here are some pictures of the print:

This was printed with the Silver PLA that came with the Ultimaker, with the following settings:

Layer Height: 0.3mm

Shell Thickness: 1.2mm

Retraction: On

Fill Density 10%

Print Speed: 50mm/s

If anyone has any idea what could be causing this problem, your help would be greatly appreciated!
