Troubleshooting NexaX

NexaX says my file is corrupted. What should I do?


NexaX will notify you if your .stl file has mesh errors as there is a chance it will not be able to slice it properly which will lead to a print failure. When you come across this, you have 3 options:

  • Adjust the export settings on your CAD or 3D modeling program and try again.
  • Slice the file anyway but inspect the individual slices using the preview box after it has saved. 
  • Repair the .stl file and then slice it.

The best option is likely to repair the .stl file. Unfortunately, NexaX currently does not have this capability so you will need to resort to third party software. Some great, free solutions include: 

Why is NexaX slow?

NexaX has to run some complex calculations, especially when hollowing a part, generating support and creating the job file. Please make sure you meet at least the minimum recommended specs below. If you would like even better performance, you may need to upgrade well past these specs. 

  • RAM: 8 GB

    OS: Windows 10

    Graphics Card: NVIDIA GeForce GTX 1060 or AMD Radeon R9 Fury

    Free Disk Space: 30 GB

In some cases, computers with both integrated and dedicated graphics cards may default to using the integrated card for energy efficiency reasons. This will significantly slow down NexaX so it is best to configure your system to forcibly use the dedicate card for this program. For example, you can follow these steps for an NVIDIA card. 

  1. Right click on the desktop and select NVIDIA Control Panel

  2. Click on Manage 3D Settings

  3. Switch from Global Settings to Program Settings

  4. Click on Add next to the program select dropdown

  5. Select NexaX 2.0 from the list

  6. Select 'High-performance NVIDIA processor' from the second dropdown


If you run into any further issues other than what is listed above, submit a ticket to our support team or reach out to Screen shots and detailed descriptions of any errors would be most helpful for diagnosis!
