Pretty consistently, If I attempt to print a job twice in a row, the second print hangs on “Scanning material” Restarting Chrome always fixes it, but I need to reload the artwork, and reposition the art on the piece. The Yellow “Progress” bar at the bottom remains Grey.
I am not even opening the Lid between jobs.

Be sure not to print twice too close together. After the first job finishes, wait for the fans to finish, then wait for it to snap a fresh bed image and for it to say Ready in the top-right corner. Then wait another minute or so to be safe, then hit print.
For the past month or so printing too quickly after finishing a job has sometimes been triggering this hang.
