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.

    Which version of printer are you using? If it's not the "box" style the frame could have been bumped/bent  and now your Z rails are no longer at 90 degrees to your Y rails. It could also be slipping gears on your motors. Make sure everything is tightened, squared, and leveled.

     

    As for your "stringy" problem. When you first set up Pronterface, you'll need to input your machines settings. To include nozzle size and filament size. By default, Pronterface sets up with 3mm filament. Most likely, you are using 1.75mm filament. It's a volume issue. There is more volume in a length of 100mm filament of 3mm than 1.75mm. To compensate, your printer is extruding less "volume" with 1.75mm, but the same "length" that would have been used with 3mm. (Are you lost?)

    Well actually I've gotten pronterface to run properly with files I've downloaded just fine, it's my own files that have the issue. Everything else prints perfectly. it even shows my files in the little print viewer as more of a collection of strings than a 3d object. I have noticed that the x endstop switch is behaving a little odd now, but I'm not sure how that explains how only my prints are affected. Also, my printer is a prusa i3 I got from mixshop in Toronto and everything appears to be at 90*, at least nowhere near the angle my prints come out as.

    When Slic3r makes scattered bits like that, it usually means that the file is not "manifold". In 3d space, each polygon, face, edge, and vertices have a direction. They all need to be facing OUT. On youtube, find Cannedmushrooms page. His name is Jason Welsh. He has many videos to help explain all about 3d objects and and 3d printing. You can also use NetFabb. It doesn't always work as intended, but it's a good start if you don't want to learn to use other 3d software.

     

    Depending on your X-endstop issue. It may be loose connections, loose screw/bolt, or a software/firmware issue. If you don't find any physical problems, contact your supplier for help and troubleshooting.

    I've actually read about 'manifold' and stuff like that and get normal prints excluding the slant out of repetier. Come to think of it, the weird print in pronterface was likely because of that, since repetier has the deep analysis button, which seems to fix all issues with the file and pronterface doesn't have that. Anyway I have fixed the connection issue for the X endstop and the prints are now around 5* slanted instead of about 45*. Less annoying, but still annoying.  I'd write it off as just he endstop, except its only my files that are affected still.
