Cleaning your file system memory on the Ruida Controller should be part of your periodic maintenance. The controller's onboard memory is limited and as it nears its max capacity of 128mb/1 Gig (Model Dependent) we have seen some file corruption and file sending issues. So it is always best to clear unused and unnecessary files loaded into this onboard memory.

Below you will find the processes to clear files directly from the controller and from Lightburn.

Deleting files Using Lightburn

This procedure should work for all Thunder Laser Gantry based machines that use a Ruida controller.

When deleting files using Lightburn you should:

  1. Open Lightburn and have it connected to a powered ON laser
  2. Open your File List tab (if the File List Tab is not visible go to the top taskbar in Lightburn and select Window > File List)
  3. Once you open your File List press Refresh to read the file list from the controller
  4. Select some or all of your files for deletion and delete
