Hello everybody!
I'm printing with my Mosaic and Skeinforge 50.
I've been doing some adjustments in the Skeinforge profile to improve the quality of my things printed.
However, I can't improve the "plastic sewing" (I'm not sure how do you call this in english..). Is the point where the extruder starts and finish each layer.

I attached two photo to show this.

 



Anybody can tell me about the Skeinforge parameters to smooth this "plastic sewing"? 

Thanks in advance,

Now keep in mind that I may be a complete fool, if it is possible to have the endpoints of each layer be varied then the effect won't be as pronounced. I'm am basing this on molding processes as I do not, as of yet, have a 3d printer, but if the variance and buildup caused by the oozing at the stop points is not allowed to build up in one area than it should be less noticeable. You may also consider adding a junk item as a stopping point so that all of the buildup would not be in the actual model, but instead on an extra piece.

What is your retraction speed set to?  It could be trying to retract too fast, skipping steps, and then when it tries to un-retract, it could be squirting out a bunch of extra plastic.

under Dimension in Skeinforge, mess with the following settings:
Extraction Speed 10
Retraction Distance 1
Restart Extra Distace 0

Mine is settings are above. But yours might need to be different.

Good Luck Sir.

Ok. Thanks for all the answers.
My actual settings are:
Extraction Speed    18 

Retraction Distance     1 
Restart Extra Distace   0 

I'm going to probe with 10, as neoteric has told me. Thanks again.

Why are you using skeinforge instead of Slic3r or SFact?

Good question....I'm not sure! XD

I downloaded the skeinforge profile from this google group and star to print.
However, I'm really thinking about starting using the last version of Slic3r.

Sfact? If you are going to use a skeinforge derivative Cura is a much
better choice. It has many of the same user friendly changes and is
4 times faster that SF. Nice UI too. Made by a member of the Ultimaker
community.

Interesting, this is the first time I ever seen mention of Cura.

As I said mostly used in the Ultimaker circles but if you
like skeinforge it uses PyPy to speed SF up by about 4x.

The RC2 has slic3r and the accelerated SF built in and bundled with printrun.
The setup has a handy E value calibrator for odd/custom extruder gears and a
link to Daid's Marlin customizer/builder. Where you can check boxes to roll up a
marlin for a variety of machines.

It has UI 3d viewer similar to RepG and a slice viewer.

Also starting to add some fancy multiple object options. Including a project planner
that when finished will allow you to print multiple objects one at a time on a large enough
build platform. Reduces strings between each object and reduces failed long prints
since each object is printed individually.

For those who might be looking for more information about Cura rather
than just the download page (which does not seem to include any
documentation), look here:

I like Cura. Looks really nice!

Has anybody used with MG_Mosaic printer before? 
I would like to talk about the firsts steps...

Underneath it is just jazzed up skeinforge.
So you'd set it up in the same way as you would skeinforge.

Getting it to talk directly to the printer would require a marlin firmware.
Or you can send the gcode via other more usual means.
I use it to generate gcode for my cupcake, a reprap and an ultimaker.
