It fixed itself when I booted it all up today. YAY!
Not fixture saving after the last run may have turned out to be a good idea.

At least I've figured out about the 'MARK_FUN' error. First boot it didn't come up and the steppers bumped every full rotation. Booted it again until the error appeared and it ran smooth.
Definitely have slight issues with the PC.
