My first venture with the Smoothieboard 4XC has crashed (but not burned…, at least there was no smoke). I hope someone can help.
I bought board about a year ago, have just completed a REPRAP type 3D printer and was looking forward to great progress over my Prusa 1 and Omni3D Architect.
I plugged the board into my laptop via USB and after bit of light flashing was awarded access to the SD card as predicted. Everything looked in order so I copied over the card contents and have these stored on my laptop. (Backup-Firmware; Documentation; Drivers; Models; Software; Source; config; etc including FIRMWARE.CUR,)
At that point, I decided that as the SD contents were a year old it would be a good idea to update. Following the instructions on (I think) GitHub I copied down what I thought was the latest firmware and copied it onto a new (FAT32) SD card. On trying to boot the board with this I got one red LED and the others solid greens. I also got the laptop message. “The USB device attached has malfunctioned”.
I then put the original SD card (still as supplied) back in the Smoothieboard but was welcomed by the same solid greens and “malfunction” message.
I guess I need to reinstall the Backup-Firmware from my copy of the supplied SD card. Is this what is required and how do I do this?
