Problem with speeds First layer/infill V1.1.7

I have problems generating gcode with slic3r - ubuntu :
The test print is a simple small cube.
The print speeds seem to be wrong - the first 3 layers are at double speed - other layers are quite slow - solid infills are extreme fast.
I cannot explain this behaviour from the settings. Please have a look on the feed-rates :

Hi,

I have noticed this as well... try going up to 1.2.6, they seem to have fixed it there.

Gray

I have the same issue.

Thanks, i will try that.

I have just tested with 1.2.6.
Speed of the layers with solid infill is ok.
Speed of the perimeters and infill is much to slow. It is about 54% of the setted value.

Cooling?

I turned off the autocooling and now everything prints according the settings.

Gruss,

Hi,
got a tip - my problems were generated by the minimum layer time feature, for slowing down prints on small objects to give the layer enough time to cool down.
Can be found in Extruder settings - cooling.
On larger objects the speed was ok.

So i think this is solved. I think this was a new features that came with an update.
