I'm back to printing USB and so far it's been solid. I've seen it before though. Print for a few weeks fine and then it starts pausing again. Very strange. So far so good though.
On the main screen, please have S3D default to the last process used instead of the last process on the list. Also, After you hit prepare to print, default to the last process used instead of automatically selecting all of them
Interesting though I haven't tried it, others seem to print ok on Windows 10 with other packages such as Repetier, Craftware, etc. Any word from S3D on this?
