I have been using pronterface software with good success. However, occasionally I get a message similar to : Warning: The input file is not manifold near edge 26.000000-29.000000. You might want to check the resulting G-code before printing. => Processing input file => Processing triangulated mesh The model has overlapping or self-intersecting facets. I tried to repair it, however you might want to check the results or repair the input file and retry. I have updated to the most recent version of the software ver 0.8.3 and yet I still get these messages. Any ideas ?? https://reprap.org/forum/read.php?1,138263,138263#msg-138263 Sat, 18 Jul 2026 23:59:00 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,138263,138349#msg-138349 https://reprap.org/forum/read.php?1,138263,138349#msg-138349
But I'm ranting, sorry. ^_^

Both skeinforge and slic3r can now slice almost everything fine, so I still use STL, I just make sure my meshes are as clean as possible. With OpenSCAD this includes modelling in a way to avoid intersecting faces and artefacts where you can. With Wings3D it comes down to make a clean quad mesh with proper edge loops. For others broken STL files, netfabb often can fix them enough to make them printable.

Slic3r also supports AMF and OBJ. I've used OBJ as a transition format between 3D programs for along time, and find it very versatile and stable. When exporting OBJ from Wings3D to slic3r, just make sure you triangulate the mesh and switch Y and Z axes, and it seems to work fine.]]> Nudel General Sun, 17 Jun 2012 19:58:54 -0400 https://reprap.org/forum/read.php?1,138263,138347#msg-138347 https://reprap.org/forum/read.php?1,138263,138347#msg-138347 HereIgoAgain General Sun, 17 Jun 2012 19:06:21 -0400 https://reprap.org/forum/read.php?1,138263,138271#msg-138271 https://reprap.org/forum/read.php?1,138263,138271#msg-138271
You can sometimes fix it by running the file through netfabb basic, and repairing it with "remove degenerate faces", or editing it manually with a mesh editor (if the editor can even import the damaged STL).

Many times slic3r does a good job of fixing it automatically though, so just preview the gcode by scrolling through the layers in pronterface to make sure everythings okay.]]> Nudel General Sun, 17 Jun 2012 12:14:40 -0400 https://reprap.org/forum/read.php?1,138263,138263#msg-138263 https://reprap.org/forum/read.php?1,138263,138263#msg-138263

The model has overlapping or self-intersecting facets. I tried to repair it, however you might want to check the results or repair the input file and retry.
