I have found a fundamental problem with the CC1 Canvas upgrade kit's manual. The QR code on page 07 is a faulty link - there isn't a video there.
This would be quite useful just now, as I've just received my kit...
I have an issue that maybe I should have anticipated...
I have been running my CC1 on OpenCentauri, and have just installed my newly-arrived Canvas system. The trouble is, when I turn it on I am stuck on the OpenCentauri startup logo and, after a while, all I see is the logo together with flashing red lights on the Canvas unit - no menus on the screen.
I probably should have rewound OpenCentauri out and reinstalled some original firmware version, then done the Canvas upgrade. Unfortunately all Elegoo offer on their support website is "OTA upgrade recommended" with no downloadable version.
Now I am looking for suggestions for sorting out the problem and moving forward...
