This is a VERY important upgrade. Look under the 'Activate' tab for the Cube3.
IMPORTANT: If there is an underscore in the name, REPLACE IT WITH A SPACE.
I have to go our now. But, on my return this evening, I will discuss the ramifications of this firmware update and how to take advantage of the new features.
In the meantime, I would make a mad dash for the site and download the update. :)
This update includes a new PURGE JETS function that promises to be useful in clearing clogs!
