Known Shell-Issue for 14.07?

[bergedorf 0]

Hi,

is there a known issue about the outer shell?

Every piece i print looks like this:

It looks like the object is printet without an outer shell...

Is there some workaround or a option i have overseen?

This looks more like massive and constant underextrusion than it does a Cura problem.

It looks like the first few layers are fine, but starts to under extrude for the subsequent layers. Watch the extruder to see if it's grinding down the filament after the first few layers.

Which machine? As that's clearly an extrusion problem (I've seen lots of those in my early days)

Hi,

sorry for the wait.

Seems right to be an extrusion problem. Had time to make a few tests.

Sometimes the filament stuck and is not properly transportet by the extrusion-motor.

I had to lower the printingspeed to minimize the grinding of the filament how Valcrow advised.

Printer is a Prusa Mendel
