  1. You are set then. Supports will be added automatically. See the Preview "tab" in the header. It will show you what will be printed without actually printing. All settings have tooltips. Read them. This setting is useful for advanced users, but it will not help you with what you are doing now.
  2. The bottom of the sphere will need support to print.
  3. Unfortunately, Cura Connect Ultimaker Connect is not open source; even if you can just copy and modify some Python code, you may not be allowed to do that.
  4. Yes, you can ignore the red here. You can even turn it off if it bothers you in the General preferences. Sketchup is generally not a great tool to make models for 3d printing. It will very easily let you create models that won't print well, or at all. The normals thing though is fairly easy to see and fix in Sketchup; in Sketchup normals that face the "wrong" direction get a blue-ish grey color (as opposed to the regular white). You can right-click on a face and choose "Reverse Faces" to flip the normal from facing inward to outward (and vice-versa).
  5. Sorry, I forgot the “other” category was decommissioned in 4.2
  6. The "Mark2 for Ultimaker2" printer can be found in the "Other" catagory.
  7. The red is intended to show areas that need support. The fact that the sphere shows red on top means that the normals of that part of the mesh are reversed.
  8. For Ultimaker printers, the estimations that Cura makes are fairly accurate in my experience. For other printers, Cura may be missing information about how fast these printers are configured to move. That makes accurately predicting print-times impossible.
  9. Ok, if the web interface won't work, then neither will the OctoPrint Connection plugin in Cura.
  10. Thanks. I have reproduced the orange triangle, and will see how to make it behave. The orange triangle is supposed to show when there are no quality profiles for the chosen combination of material and nozzle size. In this case there clearly are profiles, so the warning should not show.
  11. * In Cura: File -> Save... * Upload the resulting file somewhere (eg dropbox, google drive, one drive, etc) * Post a link here
  12. About that orange triangle, that's a feature of the Sidebar GUI plugin that seems to be misbehaving. Could you post a link to a Cura project file?
  13. In Preview, change the View type to X-Ray. I think you will see parts of the geoemtry highlighted in red. This means there is "internal geometry". I think you did not properly "boolean"/"union" the tabs to the housing. This throws off the slicer.
  14. How about if you manually upload and print the gcode file via the browser interface? I would like to know if it is my plugin, or OctoPrint itself.
  15. Unfortunately the reality is probably more complicated than a fixed percentage. Try printing a 40x40x10 block, and you'll likely get a different percentage. Print your 20x20x20 mm block at a different speed, and the percentage also likely changes (though more subtly). The difference is probably mostly due to what is called "die swell". The material that gets extruded from the nozzle does not have the exact same diameter as the nozzle; due to pressure in the print head and in the bowden tube, the material expands outwards (horizontally) as soon as it leaves the nozzle. This expansion isn't constant either; it depends on the pressure and the pressure depends on print speed, and more parameters. In most cases, you can use the "Horizontal Expansion" setting to get closer to the original measurements, but getting them exact is the holy grail of 3d printing.
  16. Cura stores a configuration per version, so you can always go back to a previous version if a new version doesn't work for you. When there is no configuration folder for the version you are running (eg when you run Cura for the first time), Cura will see if there is an older configuration that it can copy over and upgrade so you don;t have to reconfigure everything. I think in your case it picked up a configuration from an older version that you did modify (you added a Creality CR10 definition). That old configuration points to a printer definition that does not exist in the new Cura. This causes an error. Removing the upgraded configuration will only result in having the same old configuration with the reference to the missing definition being copied over and upgraded again. By removing the contents of the folder, but leaving the empty folder in place, you trick Cura into believing there is a configuration for this version of Cura in place (there's just nothing configured). So this is the way to start fresh without copying an older configuration.
  17. Glad you are laughing, but I'm not an Ultimaker employee, so I don't get those logs. Neither do most people on this forum. Did you modify the Cura 4.2.1 files in any way (eg to install the Creawsome mod)? Or have you done so in the past? Creawsome mod is now integrated into Cura. I'm guessing you have tried the "Backup and reset configuration" button and restarted Cura? Something to try is to press the "Open configuration folder" button. Close Cura, and then remove all the files from the configuration folder, but leave the empty folder in place. Then restart Cura.
  18. I can only tell what we’re missing: the contents of the detailed crash report. Without that we can only guess.
  19. Your question starts out very reasonable, but I wonder what you wanted to achieve by adding the "(better)" there. It makes me want to answer with "you may want to get a different (better) printer". Cura supports printing over USB. Ultimaker does not offer support for it though. It may work, it may not. If it doesn't for your printer, Ultimaker is not going to fix it for you. Perhaps you can ask your printer manufacturer to contribute a fix. My personal advice would be to get a Raspberry Pi (model 3 or 3+) and install OctoPrint on it. Then you can use the OctoPrint Connection plugin to send the gcode to your printer, and your Mac will not have to stay connected to the printer during the print.
  20. That is correct.The diameter that is set in the Machine Settings is overridden by the diameter from the Material. The value in the Machine Settings is really only there to switch the list of shown materials to either 1.75mm or 3mm filaments.
  21. Sorry, you suggested it hung on that plugin, I told you how you can manually remove that plugin. I did not mean to say the plugin is broken (though I’ve heard thingiverse often is)
  22. The Printer Settings plugin comes with a big fat "USE AT YOUR OWN RISK" warming, and this is exactly why. The plugin allows you to make additional settings visible. Uninstalling the plugin makes these settings invisible again, but the values you entered are still there! This is the same as for example turning on supports and then making the "Enable supports" setting invisible; supports will still be printed, even though you don't see the setting anymore. What you enter in the "sidebar" will always override what you set in the material or machine settings, whether it is visible or not. The main reason that the Material Diameter was removed from the "sidebar" is that once you have changed the value there, switching to a different material that has a different diameter set would no longer change the effective material diameter because the sidebar would still have a value that would override it.
  23. Thingiverse has been down a lot lately. You could try removing the thingiverse plugin manually. On Windows, go to %APPDATA%\cura\4.2\plugins, and remove the thingiverse plugin folder.
  24. What happens when you press Cancel?
  25. Do you happen to have multiple monitors? If so, can you try temporarily disconnecting one before you start Cura?
