This question gets asked every so-often. Here's another thread with some more info:

Intuitively I would say there's something different about the 3rd printer definition. Hard to tell what is happening without the code.

Er... how? Changing the layer height would change the number of layers needed to print the whole model. There's no way you can do this with a simple gcode command. You can change the amount of material that is deposited (and as a result the line width), but not the distance between layers (the layer height).

This means the model is contained in a group. You can "ungroup" it to get rid of the bounding box.

Well, I just quoted the other guy...

Quoting @ghostkeeper from this reddit post:

That would not have helped in this case. You placed the file in the correct location, so you did the "import" part correctly. A (community-moderated?) Marketplace for postprocessing scripts could be interesting though.

It could be nice for others if you shared what you had to change to get Cura 5 running nearly as fast as Cura 4.13

The postprocessing script must be named "TempTower.py", or you must change the class name inside the file to match the file name.

The resource folder has changed locations a bit. The folder you are looking for can now be found here: C:\Program Files\Ultimaker Cura 5.0.0\share\cura\resources\definitions

Do you have multiple displays?

Please post a link to your Cura.log, which can also be found in the configuration folder. Tip: the proper configuration folder can be found via Help -> Show configuration folder. There's a "scripts" folder inside the configuration folder.

There may be an issue in Cura 5 (re-)installing plugins. Please try the following: * In the Marketplace, uninstall the plugin(s) that are not working * Restart Cura (this is important) * In the Marketplace, reinstall the plugin(s) * Restart Cura again. Note that the "Material settings" menu item has been moved to the Material preferences dialog in the current version of the plugin:

Please try the following: In the Marketplace, uninstall Arc Welder Restart Cura (this here is the important bit) In the Marketplace, install Arc Welder Restart Cura again. It seems there may be a bug in Cura 5 where removing and installing (or updating) a plugin without restarting Cura after uninstalling will result in Cura thinking and showing the plugin has been installed without the plugin actually being present on your system.

If you want to use the plugin now, you can download it here: https://github.com/nallath/CuraOrientationPlugin/releases/tag/v3.7.0 Download the v8.0.0 curapackage, and drop it onto the buildplate in Cura as if you were opening a 3d model.

In previous versions, where this also happened to people, this could be fixed by unchecking the "Restore window position on start" option in the General preferences. Does that help in Cura 5.0?

The new version of the Auto Orientation plugin is still awaiting approval for inclusion in the Marketplace.

Not out of the box. Where would you like them to pop up instead?

You may have to move the settings floater a bit to the left; the vertical slider is obscured by your settings. I am working on finishing up the Sidebar GUI plugin for Cura 5.0, which from how you have set up your settings bar seems to be what you want. It puts the settings into a "sidebar" like it used to be in Cura before version 4, and moves some UI elements into what I think is a better place (like the vertical slider to the left of the sidebar). A prerelease can be found here: https://github.com/fieldOfView/Cura-SidebarGUIPlugin/releases/tag/v4.3.0-DEV On that page, you will see curapackages compatible with different versions of Cura. For Cura 5.0 you will need to download the file ending with `Cura5.0.curapackage`. After downloading that file, drop it onto the 3d viewport in Cura 5.0 as if you were opening a 3d model. You will then be prompted to restart Cura.

The red on the "Prepare" tab is a visualisation of what parts of the model need supports. However, this visualisation depends on the surface "normals" to be oriented the right way. In your case the normals seem to be "flipped" on some areas, which causes the red "needs support" visualisation to show up on the top of the model instead of on the bottom of the model. The "Mesh Tools" plugin from the Marketplace has a function to "Repair model normals", which would normally correct this issue with your model, putting the red on the bottom of the model where it belongs. However, your model has many more issues that make it unsuitable for printing as is, and it needs to be repaired or remodelled before it can be succesfully printed. The application "3D Builder" (which comes with Windows 10) seems to do an ok job at repairing it.

With the Ultimaker 2 you don't select the material in Cura, but on the printer. The original idea was that you could slice once, and then print with different materials from the printer LCD. That was an interesting idea when the Ultimaker 2 was launched (at the time there were only 2-ish materials that people printed with regularly), but since then people have come to the realisation that you really need to slice differently for different types of materials (eg different types of adhesion, different optimisations to support structures). So for the Ultimaker 2+, you can now select the material in Cura. But the Ultimaker 2 is stuck with the original "no materials" idea. But there's a workaround. In the Machine Settings, you can change the G-Code flavor from "Ultimaker 2" to "Marlin". This will give you full control over all material parameters in Cura. There's a catch though; if you print from SD, the UM2 will warn you that the gcode overrides the material parameters set on the printer. That is fine though, just ignore the warning; you wanted to override those settings.

If you can reproduce this (ie: if this always happens when you multiply this particular model this particular number of times), then please report it on https://github.com/ultimaker/cura/issues, because this is certainly a bug.

"Make overhang printable" can be a nice tool in your 3d printing toolbelt, but it is not magic and you should always consider if it would not be better to fix the model in a modeling package.

That is an interesting find. I'll see if I can help more people with that.

Where was it then?
