Hi all, I sliced the attached model with the PLA 0.2 profile with Skeinforge and was wondering why the gaps (marked in the pictures) appear in the sliced model? Can I do something with the settings to get rid of them? They don't show up when the model is sliced with the PLA 0.3 profile. Much thanks in advance, Niels https://reprap.org/forum/read.php?292,280726,280726#msg-280726 Tue, 06 Oct 2026 14:57:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?292,280726,288940#msg-288940 https://reprap.org/forum/read.php?292,280726,288940#msg-288940
Just wanted to let you know that if you first export your sketchup file to .dae and then convert it to stl with another programme (I used Meshlab), the model is sliced correctly with Skeinforge (no more gaps in this case). So a little work-around if the normal stl-export of Sketchup gives you problems during the slicing process.

I haven't opened sketchup since I looked at it.]]> Ralph.Hilton Mendel90 Sat, 28 Dec 2013 16:37:26 -0500 https://reprap.org/forum/read.php?292,280726,285291#msg-285291 https://reprap.org/forum/read.php?292,280726,285291#msg-285291
I use sketchup because I've learned to work with it before I got into 3d printing, and now I simply don't have time to learn another programme. But with having to redraw a part when a dimension is off I wish I had learned to work with a parametric cad programme :(. Maybe when I have the time again, I'll have a go at it. I'm also very visually oriented so I'm a bit scared of Openscad ;)]]> Nilez Mendel90 Fri, 27 Dec 2013 10:48:25 -0500 https://reprap.org/forum/read.php?292,280726,283358#msg-283358 https://reprap.org/forum/read.php?292,280726,283358#msg-283358 Ralph.Hilton Mendel90 Sun, 22 Dec 2013 13:13:00 -0500 https://reprap.org/forum/read.php?292,280726,281714#msg-281714 https://reprap.org/forum/read.php?292,280726,281714#msg-281714 Nilez Mendel90 Wed, 18 Dec 2013 13:19:27 -0500 https://reprap.org/forum/read.php?292,280726,281351#msg-281351 https://reprap.org/forum/read.php?292,280726,281351#msg-281351
Also the 0.3mm PLA profile works, so it must be depend on line width and layer height, which determines exactly where it samples the STL. I can't see anything wrong with the STL but I never get errors like that with SF myself.]]> nophead Mendel90 Tue, 17 Dec 2013 19:46:33 -0500 https://reprap.org/forum/read.php?292,280726,281324#msg-281324 https://reprap.org/forum/read.php?292,280726,281324#msg-281324 Nilez Mendel90 Tue, 17 Dec 2013 17:55:20 -0500 https://reprap.org/forum/read.php?292,280726,281288#msg-281288 https://reprap.org/forum/read.php?292,280726,281288#msg-281288 nophead Mendel90 Tue, 17 Dec 2013 16:38:45 -0500 https://reprap.org/forum/read.php?292,280726,281251#msg-281251 https://reprap.org/forum/read.php?292,280726,281251#msg-281251 Nilez Mendel90 Tue, 17 Dec 2013 14:57:32 -0500 https://reprap.org/forum/read.php?292,280726,281239#msg-281239 https://reprap.org/forum/read.php?292,280726,281239#msg-281239
So they're not solid :S. Scratching my head now about what to do about it since inside Sketchup the model proves solid. Can it get non-manifold in the process of converting it to STL? I'm sorry if I'm asking these things in the wrong place. Just wondering if someone maybe recognizes this problem. But thank you very much for checking my stl's, because I know where the problem lies!

The gaps do show up in the print so it isn't just an artefact. The strange thing is that when I slice only one segment or block of the "dodecagonal" model the gaps don't turn up in the block (photo attached). As soon as I add another segment the problem shows. I guess maybe it has something to do with the orientation (different angle ) of the blocks which causes problems for Skeinforge? A remarkable thing is that the gaps don't show up if I slice the model with PLA 0.3 instead of 0.2. I've also attached two stl files and gcode files in case anyone wants to take a closer look.

Niels

Edit: I'm pretty sure the model is manifold in Sketchup by the way. I use several pluggins to verify the object is solid.]]> Nilez Mendel90 Tue, 17 Dec 2013 09:59:14 -0500 https://reprap.org/forum/read.php?292,280726,280759#msg-280759 https://reprap.org/forum/read.php?292,280726,280759#msg-280759
Try modelling the same problem area with more sections in your tube....]]> Traveltrousers Mendel90 Mon, 16 Dec 2013 17:36:47 -0500 https://reprap.org/forum/read.php?292,280726,280747#msg-280747 https://reprap.org/forum/read.php?292,280726,280747#msg-280747
Are you sure it is not just a RepetierHost rendering artifact? You could try viewing your G-Code online here and see how it compares.
