Sorry, been waiting to get my first posts moderated . . .
No, I just got the message and the option to Reboot as a button on the touch screen.
We send the print/project to the Ultimaker Digital Factory and then print it from there.
I was just posting here to see if it's a known issue . . .
I followed the advice on the Ultimaker website and disconnected the print head cable and reconnected it, it looked OK, after a little while we resumed part of the print (its multiple parts) which completed without issue, then did the final larger part of the print (18 hrs) which has also completed without issue.
Perhaps it is bead blocks on the internal SSD, is there anyway of checking the status of this ? or doing the equivalent of a disk scan to mark any other bad block in advance of our next 24hr print 😉
