I have created 4 slicing profiles for skeinforge .1mm w/raft, .1mm w/o raft, .3mm w/raft, .3mm w/o raft.  I also like that it uses pypy(much faster slicer than python).

Slic3r works fine but has terrible support material, and no raft, however the prints are nice.

But when I use Skeinforge, the print speed is SUPER SLOW. It's probably 5 times slower.

If anyone has found out how to bring it back up to speed I'd be interested.

Thanks

Also in Slic3r you are missing G92 E0, which is needed to reset the extruder.  As is, it might try to spit the filament out the back when you start, depending on where it thinks the extruder left off.

I think this might answer the question I was just about to ask...

I got a new computer, so rather than just install Pronterface/ReplicatorG, I bit the bullet and upgraded to RepetierHost, and Lawsy's firmware.

I dig RH alot.  It's a much nicer experience, until I hit PRINT and the filament reversed out, and then proceeded to not extrude -  I think it wasn't turning, but I am not sure just yet.

I also tried Pronterface - and that prints fine. I'll be looking for the G92 E0 command...

great work on your upgrade blog,  Ian

Repetier does work quite well. Still having issues?

slic3r 0.9.7 is now out.

Ian posted his .1mm slic3r profile over in another thread about hi-res printing.  After being turned off from dialing in slic3r since my skeinforge printed so well, I decided to load up Ian's profile and see how it worked.

It is important to change the filament diameter and extrusion multiplier after loading the profile and that your bed is already been leveled. I just did several of these steps yesterday, so I thought I would add in my notes.

I followed the instruction on the slic3r github for calibration. After you run your calibration test following those instructions, you might get a value below .9 for your extrusion multiplier.  Slic3r recommends using a value between .9 and 1.  If your number is outside of those bounds, it is probably best to adjust your e-steps (how many steps the motor turns in order to extrude a given length of filament) and then run this calibration again.

There are 2 ways that I know to adjust this value.  You can follow Ian's guide on extruded calibration to modify this values in the firmware itself.  This has the added benefit of being dead on and automatically being setup in any slicing program. Or you can adjust this value via the gcode, which is the method that I used for simplicity.

I added this to my start gcode per Ian's suggestion, but added it to my slic3r printer profile so that it is generated every time I slice:
M92 E109

This code (I believe) tells the firmware to have the extruder motor turn 109 steps instead of the printers default value.  The 109 is the value to use if your extruder was feeding ~120mm of filament when you told it feed 100mm.  I knew from a clumsy extruder calibration attempt earlier that was the case with my extruder as well.

When I printed the slic3r calibration stl again, my walls were still to thick but my extruder multiplier was already at .9, so I lowered the 109 to 108 and once again printed the calibration stl.  A few stl prints later and I landed on a setting of M92 E105 and I am finally getting .42mm thick walls, time to print another yoda!

Ian talks more about this in his Setting the Flow Rate post and he has lower multiplier values then .9, I just wanted to obey the tooltip that slic3r was giving me.

I really like the Repetier / Slic3r combo from a workflow point of view but Skeinforge still does better slices for most of the stuff I do.  The support that it generates is both more stable and easier to clean off. Especially when there are large areas of support.
Now to only get Skeinforge to work Repetier.
