Hmmmm…I think we’re on different versions. Might be because you are working from a smaller device?
I think that is the same as this error message, but it looks like it has been expanded. The one that I have will allow the print, all you have to do is walk over and press the blinking button on the machine. (It used to have a “Continue” button down at the bottom of that panel, but they do make changes once in a while to improve the workflow.)
If your button is blinking, you can start the machine and it should run. If not, try hiding that panel…and if there is a Continue button at the bottom you can press it.
Although…it looks like yours is stuck Uploading at the time that you shot that screenshot, so that might be the problem there. Try a different file, and see if it does the same thing. (This one might be a file issue…the warning might have just been coincidental.)
