  1. Anything I can do to help you build one? Maybe I can do the build for you? I don't have much experience with Python... but might be able to follow some instructions 🙂 PS: I am using the "Sidebar GUI" plugin. On that outdated OS version of yours, it causes the slice/save dialogue to double up: Might want to check if that is also solved in your latest release.
  2. Here is a simple test object Test - line width.stl
  3. Sorry, spoke too soon. Seems like it has other weird issues (which do not happen when Line Width is set to 0.39mm).
  4. Well, I tried the osx version you have in the dropbox. And that solves this issue 🙂
  5. Yeah, you can clearly see the issue with the uneven multiples of the Line Widths: I am on mac, so cannot try out your version.
  6. Cura seems to not deal well with walls that are an exact multiple of the Line Width. Example: This is a simple object with 3 walls of 2mm thick. With a Line Width of 0.4 and Wall Line Count set to 3, it should just use 5 lines to fill the wall. Instead it does this! (Also known as a printer-killer!) If I set the Line Width to 0.39 I get the desired result: But I shouldn't have to do that. This is a rounding/calculation BUG in Cura. Also, printing a 0.4mm wall (for instance for creating custom supports) does not work. This is the same object, but I added a cross in the hole with walls of exactly 0.4mm thick. It now does not matter if I set the Wall Width to 0.4mm or 0.39mm. Cura doesn't want to print that as a single line. (Yes, the Print Thin Walls option is on) If I change these thin walls to 0.41mm this, Cura does print them as a single line. So here is the object with 0.41mm walls. And Cura set to 0.39mm Line Width. Again, I shouldn't have to do this to work around issues in Cura.
  7. PS: I am printing on an Creality Ender 3 Pro.
  8. I created my own 'Filament Change' plugin, as the ones in Cura (FilamentChange and PauseAtHeight) both seem to have issues. My plugin inserts the gcode as I want and it works pretty well. But, after it resumes printing, the printer starts by extruding a large amount of filament on the starting position on the object. No idea why it does that, as I do a Extruder reset before the end of my code G92 E0 ; Reset Extruder Anyone any idea why this is happening and how to solve it? Here is a snippet of the full gcode: ...
