  1. Is the calculation is made regarding the extruded length available in the .gcode file? For the density, I advise you to choose 1.24g/cm3 which is 1.24 x 10-3 g/mm3 To make it even more easy (you probably already did that), you can sse it this way: m = V * rho equivalent to m = S * l * rho = l * K m, being the mass (in grams) V, being the volum (in mm3) l, being the length of the filament (in mm) rho, being the density (in g/mm3) K, being the linear mass of your filament (in g/mm) Then you have: K = (pi * d^2 /4) * rho
  2. Hi @amrahabibovic, I struggled a lot on this and maybe together we can find something out 😉 Thanks @utopiah to ping me on this. Here are some questions for you, and if I understand your problem I can provide a guideline to help you on this: 1) Do you want to slice a part with the parameters you have in Cura (the GUI), but you would like to do it with a command line? 2) Do you want to slice only one part at a time? 3) Would you like to orientate them in order to have a part well orientate and reduce the printing time? If the answer to those 3 que
  3. Hi, I know it has been a while but I add a similar problem and also a solution: I tried it the same way as you: providing a json file,the stl and feeding all the parameters in a text. file. All the parameters were recovered from a .log file recovered from the log file after a slice with the machine on a file. The thing is I always add something wrong with the parameters at some points and it's hard to debug and understand which fails and why when there is more than 400 parameters. So I tried another way: feeding the parameters directly in the fdmprinter.def.json
  4. Hi everyone, It has been a while but here is the solution I was looking for: -the guy that did the auto orientation plugin is Christoph Schranz and the name of the tool is Tweaker 3 (available here). Christoph's tool can be run into command line like this one: Tweaker.py -i my_stl.stl -vb The result of this command line will be an oriented stl file with the suffixe "_tweaked" It works like a charm 😉 Enjoy his amazing work if you need it
  5. Actually the gif was a good try but a bad idea: next time I will give the link to a not referenced video on youtube which will make think simpler. Extract the matrix from the plugin could be a good idea (thanks 😉 ).
  6. Hello, @ahoeben, I feel a bit of agressivity in your message, am I wrong? And how does that help if you don't the rotation you need to apply: every geometry is different, the advantages of the auto-orientation plug in is to have a good orientation to 3D print the model. Is it more clear?
  7. Hello, I add another look about using cura in command line. Cura can be executed with command line with the following syntax (as example): curaengine slice -j my_printer.def.json -o test.gcode -l cube_v3.stl here: my_printer.def.json: is the definition of the printer. It does use another file: my_extruder.def.json which is the definition of the extruder test.gcode: it's the output of the slicing cube_v3.stl: it's the file to be sliced What I do remark, it's that at the end of the definition file of the 3D printer, there is a sect
  8. Actually what you say make perfect sense. I think that if it work the way you say, I would have to create a tool within the GUI to run the known function (center and optimize the orientation and export). PS: I did illustrate the previous talk about exporting back into a stl and the auto-orientation plugin into this little gif 😉
  9. Hello @Smithy, Actually when you open a file in Cura, it does take the stl file and center it in the middle of the bed. From that I assume it as this capability. For the orientation, the plug in auto-orientation can also work automatically when you import an stl file. Once done, you can save your positionned and oriented stl back to an stl. You can try it with a simple cube that is firstly not oriented with Automatic orientation activated. You will see it getting a good orientation. Then you can save it back as an stl. So now that we know we can do it,
  10. Of course @maht: -let say you have lots of 3D printer and lots of parts to print. All your printer have ejection system so each 3D printer can print continuously one part after another. In order to print all your parts, you need to know which parts need to be print with which machine. In order to do that, you need to slice all files and attribute them to a machine in order to be 3D printed. Then, every printer print is queue of parts in order to realize the whole production. I feel like I am not good at explaining. In the attached file I did an illustration that
  11. What is the link with using command line? How is this related to running a script to slice different files one after another?
  12. Hello, I would like to automate the production of 3D printed part. Cura could be useful for few reasons: -when you open a file with cura, it automatically center and orient the part on the bed Here is the command I use: cura cube. stl But then I don't know and didn't find any resources to save this file back to a .stl, which will be positionned and ready to be sliced with a good position and orientation. Is is possible to do that: open a file, center it, orienting the .stl and save it bakc to an .stl file? I did have a
