Cura 5.X keyboard shortcuts

With Cura, most people will only use the keyboard to enter values or file names. With the use of keyboard shortcuts, however, the work can be greatly simplified in some cases.

Here is a current overview of the keyboard shortcuts for Cura 5.X:

Increase Cura speed with plugin

Ultimaker Cura is not exactly the fastest software due to the Python programming language. Especially with many printing profiles, it becomes particularly slow.
The fact that the X40 community project supports over 50 filaments, each with 11 printing levels for each color, makes Cura particularly slow.

Not all filaments are almost always required, so I would like to show you here how you can only load your favorite materials without deleting configuration files.


The Cura Startup Optimiser Plugin

With the help of the Cura Startup optimiser plugin, you can simply suppress the print profiles released in the printer definition and then only release your favorite materials again.

Simply install the Start Optimiser plugin via the Cura Marketplace and after a restart click on Extensions -> Startup Optimizer -> Load only generic and custom materials.

After a restart, most materials are no longer displayed due to a blacklist.


Edit the blacklist

The blacklist can be found in the cura.cfg file at:

Of course you have to replace the XXX with your username. In the cura.cfg file you will find the suppressed materials in the [start_optimiser] section. All you have to do now is remove all the materials you want to use from the blacklist and restart Cura. Make a copy of the cura.cfg file before changing it. If there is an error, Cura will otherwise crash and, in extreme cases, you can reinstall Cura.

By clicking on Restore all configuration files you can undo everything if necessary. However, the blacklist is also deleted in the process.



With the latest X40 PRO Cura configurations, there is only one set of quality and intent profiles for the filament. Most of the time, black is the master color. So if the master color is suppressed by the blacklist, then all other colors from the filament will not work either. Therefore, please always remove or add all colors to the filament from the black list.



The plugin isn't exactly perfect. I've asked the developer to add a feature that will only show materials that are marked as favorites. Maybe there will be an easier solution in the future.


Cura Theme "Aqua"

Cura has long supported themes that allow you to change the color theme. Since the Ultimaker Cura theme was too dark and not happy enough for me, I decided to create my own theme.

The Cura themes are independent of the configured 3D printer and can therefore be used with all printers that Cura supports.


The new "Aqua" theme was designed with friendly blue, orange and gray tones. The rest is black and white. The theme Rev. 1.1 was developed for Ultimaker Cura 5.1 but also work with Cura 5.0. Cura 4.X is not supported!


Aqua Theme with Cura 5.1.0


Aqua Theme with Cura 5.0.0






The installation is very easy. Pack the zip archive and copy the Aqua directory to Cura's themes directory. If there is no themes directory in the resources directory, create one and then copy the aqua directory into it.

Look for the resources directory on your PC from your Cura installation:

  • Windows
    Cura 5.X (C:\Program Files\Ultimaker Cura 5.0.0\share\cura\resources)

  • Linux

  • MacOS (In Finder go to the application folder, find Cura 5.1, right click in the application, open show contents, contents, MacOS, resources)


Now start Cura and under Preferences -> configure Cura... select the General tab and then the "Aqua" theme. Close the dialog box and restart Cura for the Aqua theme to appear.



Ultimaker Cura for Weedo ME40

I derived a configuration for the new Weedo ME40 3D printer from the X40 Configuration for Cura 5.1. The basic configuration can be downloaded for free.

Since I don't own a Weedo ME40, I'm dependent on feedback from the community. Without feedback, no further development and improvement!

If you want to have the preview image displayed, you need the Cura Plugin from the homepage!

How to use the Cura X40-Community print profiles

Cura and other slicers quickly have hundreds of parameters to adapt the filament to the printer and the printed object. This unmanageable number of settings not only produces good results, but also misprints due to incorrect operation.

In order to significantly reduce misprints, it is advisable to create or use print profiles.

In the X40 community project, filaments were used that have a small diameter tolerance and are available in as many countries as possible. However, we cannot include all countries. However, the profiles can be used as templates to create your own profiles.

Please note that only the printing profiles are tested and matched with manufacturer names. Generic printing profiles are therefore more to be seen as a template for which you have to determine the optimal parameters yourself, such as the correct distances for easy removal of the support structure.


If you can buy the filaments and want good results quickly, then you should use the X40 community print profiles without making major changes. Actually, you only need to select the desired print profile and, if necessary, activate the support structure or switch/switch off the brim if necessary.


For more Information see Cura Quality and Intent Profiles



A 3D print will only be printed in good quality if the right material flow is set during printing. Even due to the tolerance of the filament, it may even be necessary to make corrections in order to get a perfect result. The flow of material is often not sufficiently taken into account by many and too much material results in overextrusion and too little material in underextrusion. Only with the right quantity is the component not only visually best, but also dimensionally.


The X40 community print profiles were matched to the AddNorth E-PLA reference material using the Weedo X40 extruder. Before you start with larger prints, you should make a test print with the AddNorth E-PLA and the corresponding print profiles. Do the flow test and then print the 20mm cube. If the cube has an edge length of 20+/-0.05mm, then everything is correctly aligned.

If the cube is too big or too small during the test, then the material flow must be adjusted to the profiles. Determine the correct value using the material flow test and correct it using the M221 command. You only need to enter the command e.g. M221 S89 at the beginning of the Cura start script and have thus adapted all X40 community print profiles accordingly.



Which materials are recommended?

The different types of plastic also have different properties. PLA is easy to process, but has the disadvantage that it is not suitable for outdoor use. The most suitable material type therefore depends on your component The filaments from AddNorth are very good, but not exactly cheap and not that easy to get everywhere. Fiberlogy filaments are cheaper and easier to get.

My tip here is the Fiberlogy Impact PLA. This PLA is not much more expensive than standard PLA, but has significantly higher strength and layer adhesion.

You can see all material tests here.


Howto create new printing profiles

I recorded how I create the 11 new printing levels from the existing printing profiles. The video in the X40 community cloud only shows the creation of the base. Then the corresponding printing test for e.g. the support structure, bridges, raft etc. must be carried out and the parameters adjusted.
