Topic: different vertical lenghts

Hello,

I've just changed to slic3r, with the recent .ini published from solidoodle.

Trying just .3mm now, but I don't know how to solve this:

This is a 20mm cube. No raft. 95º base and 195º print. I've tried 200 and 205 and base 90 to 100. Same results.
I've calibrated the amount of filament and the flow rate. Very accurate after first millimeters.

But the first millimeters doesn't have the right measure. I've attached a photo and a image to show it better.
It sticks great to the base but It deforms the size of the first millimeters...

So, tested different temperatures, changed first layer to 150% and 200%... Doesn't solve this.

I don't know what can I test further...

Re: different vertical lenghts

The bend is usually the other way around, with the upper layer shrinking inward more because they are farther from the heat of the bed, and the shrinking isn't as constrained by the adhesion to the bed.

The only thing I can think of off hand is that from the lower corners, it looks like you need to activate cooling.  The lower layers might be staying too hot and soft when the upper layers get extruded on top of them.  I don't know if that would address the inward curl.  Maybe the bed is also a little too hot for that particular filament.

Re: different vertical lenghts

Normally the base layers of an ABS print will be wider than the next layers as the plastic is kept warmer by the heated bed.  There is a possibility that you loaded the slic3r profiles incorrectly.  Can you post of a screenshot of the slicer tab interface in your repetier-host?
