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

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;

I apprecaite the other comments and will do my best to follow them. I did set up Slic3r per your video and only made changes to the Infill area. Just have to keep playing with it. I'm sure the SD2 can do it, just finding the right setting is the dea. I can't use ABS as my wife is highly allergic to most chemicals and perfumes. She was in the ER multiple times in Florida when people at her job perposly spread stuff around.

PLA is more free flowing at ABS temperatures, which is causing all your issues. You are going to have to play with your settings a lot to get it to work, as I don't believe PLA is officially supported at this time. The last one also looks like over extrusion, so you have to calibrate your extruder if you haven't already. Possibly you Z height setting too, kind of hard to tell which.
I will say that at .1mm, my printer does a lousy job filling the top in with less than 6 solid layers, depending on the infill percentage. I generally run nine and it comes out great. It just has issues with all the bridging with so little plastic that you have to build it up slowly till you get a smooth layer.

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.

Rapids shouldn't lay down filament, but if you don't pull the filament out of the extruder, it tends to seep downward, producing the strings. Your probably also running too hot for PLA, exaggerating the issue, though I have no experience with PLA.

If you have it, try ABS. Otherwise monkey with your retraction and temperature settings.

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.

I'll get a few pictures of this one and also another one that I'm having issues with the FILL on. I notice some like to go for speed but for me if it takes an hour extra that's worth it for quality. This isn't a play toy but I'm trying to output pieces I can use in my company. Thanks for the input. I'll be back with something later.

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.

If the model has flaws (maybe not manifold, or has a hole in some close spot that Slic3r tries to fix), this can cause Slic3r to be a beast and fixing it could take some time.  I'd run the model though web-based Netfabb to see if that fixes the issue.

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.

It looked good at the start and I let it run totally through which took about 1.5 hours. The piece is 1" tall with two faces 1/8" thick at right angles. One leg is 1.5" long while the other is 1" long. On the long face is a extended capital letter R and on the other face an S. On the long face there is also a 1/4" hole with an extended reneforcement circle. These letters and reneforcement face into the right angle.

Slic3r added threads linking the two right facing surfaces, letters, etc. at a 45 degree angle. These threads were random but heavy in some places and totally ruined the piece.

I then sliced another piece that consist of a thin 1/4" thick rectangular platform 3/4" x1.5" this has two square towers that vary with insets and stand 7/8" above the platform. Slic3r aded threads to just about fill the area between the two towers.

Somehow Slic3r seems to want to join split surfaces with threads. These show up in the 3D slicer rendition on the screen and also print.

I'm using PLA for filament.


I'm looking at reverting to SkienForge but wonder about getting the settings into it as I don't see how the Solidoodle2_1MM file is imported or referenced with SKienForge. Is it and if so how do you use it?
