Layers curling

[DidierKlein 729]

Hi all,

This is an issue i often have but it can be clearly seen on this object:

 

It always happens for me in these typical angles.

 

When printing it looks like the layers are curling up, on the following layers the head presses them down and the results are these ugly layers.

 

I've read on the "Show your latest print" topic an advice by colorfabb to increase the minimum layer time from 5s to 8s is this the way to go?

 

I'm wondering how this affects very small areas like the antennas of this model if it spends 8 seconds printing every layer won't it finish melting it?

 

It happens only in layers that are layed outwards of the model not inward as you can see the forehead is very nice

 

Model printed at 0.08mm print speed of 40mm/s and temp of 200°c bed at 60°c in Ultimaker blue PLA

 

Thanks all

 

Didier

Yep. There is (not yet) an agreement on that issue...
