Slic3r is a failure for me

Without files and pictures, its very hard for us to understand exactly whats happening. Its possible that it may be the model and not the slicer, so a model view would be very nice.

That said, you cant import config files between skienforge and slic3r to my knowledge.

Are you sure you aren't seeing the extruder path as opposed to the extrusion lines?  When jumping from one face to the next, the filament has to go somewhere as it seeps out.   It sounds like you need to bump up up your retraction settings. Maybe try 1.5 @ 75 mm/s.  This is much more likely than slic3r adding tons of random lines to join surfaces.  You could also reduce your temp on the extruder.

The SD .1 mm profile is made for ABS too.

The photo attached shows the issue I was talking about. That's the one on the left. The one on the rigth was printed at Shapeways using the same STL file. Also, that is the orientation on the bed. PLA, start temp. 195, second layer temp 190 onward. Bed cold with 3M Blue Painter's tape on it. The back side in the photo really printed pretty good.

This was done using Repieter-Host with the Solidoodle2-.1MM file.

Couple of more photos with similar issues. The first one is a scale (1:48) roof top exhaust fan housing. The bronze one is the one I just printed. The white one is a piece a friend printed on a Replicator (kit) in ABS. The pieces in the back are ones done at Shapeways in three scales. Issue with Shapeway besides cost, time is their Hight Resolution FUD material is very similar chemically to RTV silicone casting material and unless you coat the printings real good the RTV will bond permanently. Last is a thin piece that I started last night but it wa too late to finish. You'll notice the fill is lousy. That area in the center should have had a top layer on it. I changed setting on Fill but still had some issues. If you look real close at the tower to the right at the back corner between the two towers you'll see a black spot. That's a hollow.

One more photos, while I'm at it. I attempted to print a gang STL file that a friend has been sending to Shapeways. Basically it's a grid of plates with a gear and pawl that would let down the drop-doors on railroad gondolars. This is O scale again. Notice the plowing of the PLA. These are the same setting as the other prints.

Any help on these settings would be greatly appreciated.

For starters, your extrusion multiplier is going to be different with PLA, so start there.  An other than that, it's what he said, PLA is better at 180-185,  and might need more aggressive retraction due to its ooziness.  In EEPROM Config in Repetier, set the Maximum Feedrate for E to something like 150 so it doesn't cap the retraction speeds.  Then try something like 100 for retraction speed in the settings.

Ian, I've searched the Marlin file for buring the EEPROM and not finding what I think I should. I did do the calibration on the feedrate as per your video. I did that a few days ago before the work above. Bbut I don't think that's what you are talking about here.

This area is what I found under EEPROMwrite.h section:

SERIAL_ECHO_START;
      SERIAL_ECHOLNPGM("Maximum feedrates (mm/s):");
      SERIAL_ECHO_START;
      SERIAL_ECHOPAIR("  M203 X",max_feedrate[0]);
      SERIAL_ECHOPAIR(" Y",max_feedrate[1] );
      SERIAL_ECHOPAIR(" Z", max_feedrate[2] );
      SERIAL_ECHOPAIR(" E", max_feedrate[3]);
      SERIAL_ECHOLN("");
    SERIAL_ECHO_START;
      SERIAL_ECHOLNPGM("Maximum Acceleration (mm/s2):");
      SERIAL_ECHO_START;
      SERIAL_ECHOPAIR("  M201 X" ,max_acceleration_units_per_sq_second[0] );
      SERIAL_ECHOPAIR(" Y" , max_acceleration_units_per_sq_second[1] );
      SERIAL_ECHOPAIR(" Z" ,max_acceleration_units_per_sq_second[2] );
      SERIAL_ECHOPAIR(" E" ,max_acceleration_units_per_sq_second[3]);
     SERIAL_ECHOLN("");
    SERIAL_ECHO_START;
      SERIAL_ECHOLNPGM("Acceleration: S=acceleration, T=retract acceleration");
      SERIAL_ECHO_START;
      SERIAL_ECHOPAIR("  M204 S",acceleration );
      SERIAL_ECHOPAIR(" T" ,retract_acceleration);
     SERIAL_ECHOLN("");

Those were the only two I found across the entire file that seemed to fit. Sorry for being a dummy on this.

    SERIAL_ECHO_START;

Got that Ian. I had to set the retract to 10 not 100. At 100 if backed the filament totaly out of the extruder head. [grin]
Looks to be printing much better. I lowered the temp to 185 also. If I have issuse with this print I'll set the retract to 15 and try the temp at 180.

Again, Thanks Ian and Cwalster
