  1. I was just watching a video on YouTube that explains what I think you are talking about https://youtu.be/nQLJrSf4aXE . Hope this helps...
  2. So I was showing a friend what was going on and all of the sudden the file loads and out comes the lithophane....... IDK. I didn't change a thing. This one is going to drive me nuts... If it loaded on your machine, then it HAS to be in my Cura settings. I don't get that as i am just loading the file and not slicing it. Maybe its the Cura software way of processing the file and it uses some of the slicing settings...
  3. My bed is 220x 220x 240 the design is 150x150x20. The design is 1-3mm thick (it's a lithophane) with a base of 20. These are the exact dimensions with a difference in bases, that I always use. Nothing on the drawings have changed. My brim is 8 or 6 mm wide (can't remember). It even creates a shadow. This is all before slicing. Thanks for helping, I will try to play with the settings a little more.
  4. Let me start off with what I was doing - Making a stl file of a lithophane from 2 different sites to see which would produce a better final product (which I thought were the same settings in the online program as I used on the 11th) Loading files into Cura 4..3.0 to have the file not watertight (never appeared after loading but the plugin to evaluate file would run) Repairing stl files online with MakePrintable.com due to file size and poor cpu/gpu on laptop Loading files into Cura 4.3.0 (they were watertight but still never appeared) Loaded files into Slic3r with no changes and I got the top picture below Now I am trying to print from Slic3r but I am use to (and like a lot) Cura while I try to get help with whats going on Below are 2 files that both would not appear after loading into Cura 4.3.0 and before trying to slice. As you can see in the bottom picture, no dimensions show up for the x, y, z but there is a shadow and you can only select the object thru the edit tab in the upper left. It would not slice even though the option was there (slice in dark blue in the lower right). I displayed the about tab in case that was needed by anyone. I am truly at a loss for this strange occurrence and I know I will feel a little less then when someone points out the obvious for the solution. The last time I used Cura, was on the 11th of Oct and it loaded with no problem. I was able to print (had minor tweaking to do to it). I also loaded that same file from the 11th of Oct and Cura produced an image after loading. I have been trying to do troubleshooting for a couple days, but no luck. I think I went down the wrong path because I though it was a file setting problem. I tried 2 different sites for lithophane making - 3dp.rocks and lithophanemaker.com and got the same result. So I tried a different slicer (Slic3r). Well, Slic3r had no problem completing the task, I just had to figure what settings I needed to change for a lithophane. We will see in a few (OK, a lot) of hours worth of printing (150X150X3.5 w 20mm base with a layer height of 0.1 laid vertically).

  5. I am trying to see if there are any tool extensions for Cura 4.3.0 that allow you to measure certain points of your project in case you need to diagnose a problem with the project relating to its thickness or length, etc. This way you can check it too see if it's a Cura setting or you need to go back to the drawing board. Not a extremely important extension, just a quick tool to point you in the right direction. I haven't seen any and just thought of this. Don't really know if or how useful it may be. Thanks in advance for any help.... I only have 6 months experience with 3D printing and designing.
  6. I have just started printing lithophanes. I have done a ton of research and found so many different approaches. So i decided to try the lithophane generators online. The best two I found were 'Image to Lithophane' @ 3dp.rocks and one with many user friendly customizations 'www.LithophaneMaker.com'. After getting the STL file from there, then off to a STL repair site (initially Cura found problems the extensions could not fix) . Since I choose very high definition setting, the STL files were over 200mb and since my computer isn't that good with 3D graphics (it would lock up) , I needed a online repair program. Freecad, Blender, Tinkercad, Meshmixer, and Meshlab all can fix the STL files but they lock my computer up. So I found a great STL file repair site called 'MakePrintable' (they charge now but not much depending on what you get) and they can take files up to 500mb. I let them do there thing and pop it back into Cura, and with the extensions that Cura has it finds no holes, and the slicing shows none of the problems that are shown in your picture (use the websites especially of the STL repair sites to get the best result). I don't have alot of experience but it looks like your layer width, wall thickness, actual resolution of picture and number of walls may need to be looked at. I hope this helps. It surely did with my lithophanes!!!!! Happy printing!!!!! [gr edit: fixed text color - white on white wasn't visible]
