That is precisely what I was talking about as this dude on Youtube had Repetier do that without any extra hardware or wires. What he did was press continue and it went back to where it was and continued and he said that was built in to Repetier. Well, that isn't in Pronterface sadly. Continue is there but it is a continue where you left off not a continue on a M600 going right back where it was and continuing with the new color.
