3D printer print slant and wierd prints

fuzion_reaktor

I've read about prints slanting and sliding due to belt loosening and have had that happen to myself, but I am now suffering an unusual setback as prints of my self designed pieces all slant at a continuous slope in the x axis, yet files I download from thingiverse and such do not suffer this. I use Sketchup to design and an stl conversion extension which has worked all previous times until today. While printing and viewing files in meshlab they all appear normal in the software. I am using repetier host for my printing, I've tried pronterface and have gotten weirder prints where  the filament is extruded so thin that I get pretty much a mesh instead of a solid fill before I have to stop to prevent getting a wad of plastic stuck to my extruder again . Anyone know what this would or could be? Nothing has been updated or changed compared to when it was working before. Is this slic3r being weird or something else?

Please help, this is weird.

    It's not necessarily Pronterface that slices your files. After downloading the latest Pronterface console, have you updated the Slic3r folder? You can find the latest at Slic3r.org. 2014-7-3. In the Printrun folder, replace the old Slic3r folder with the new. You may need to input the new settings.

     

    I guess now I should ask, have you just been loading your files directly into Pronterface? Or have you been running them through Slic3r first? In Pronterface, click settings, then Slicing Settings. This will open up the Slic3r console. Make sure all settings match your machine and export the config. settings to save them.

     

    Does your "slanting" issue mean the file is printed out fairly well except a 90* wall is not exactly 90* to your print bed? Or is it a layer shifting issue? Meaning the layers keep shifting in one direction and the overall shift angle is equal to 45* and now 5*.

     

    How tall is the overall object when you notice this angle? Sometimes a "swell" or "shrink" may occur. When printing the first layer, if your first layer thickness is 0.3mm and your nozzle is closer to the build platform, this will spread the layer out wider and will look like shrinking later in the print.

    Actually I seem to have overcome this. For whatever reason the extension in sketchup was creating bad stl files. I am trying a new one (Two hours of Google searching to find it) that seems to work well and doesn't have any noticeable slant. And yes, I had tried and re-downloaded slic3r before I got the new extension and it did the same thing.

    Yes bad stl files are a very common issues.  I have seen this throughout the years.  As it seems you have fixed the problem but I will mention this anyways is that sometimes when the part is printing slanted, try to slow the machine down.  The printer is trying to print faster than what it can handle and will overshoot its theoretical location.

    Thanks, if it does it again I'll try that. Weird how everything was fine for a while then went sour so suddenly though.

     

    Thanks for your help guys.
