Software Updates

This page contains the most up-to-date or recommended version of all the firmware, software, and configuration files for your Opulo hardware.

OpenPnP Config Files (.XML)

It is important that you pick the right config file for the Version of the LumenPnP you own. Example:

If you own a LumenPnP V4.1, you must use the V4.1 config files.

If you own a LumenPnP V4.0 and haven't upgraded to the second fiducial yet, you must use the V4.0 config files.

If you own a LumenPnP V3, you must use the V3 config files.

In March of 2026, OpenPnP made a new stable release, v2.6, which is what we recommend installing now.

If you downloaded OpenPnP before then, you likely have the original recommended version, 2023-04-05.

You can check what version you have installed by following this guide. Make sure to use the correct configuration based on your version.
