Okay, first download one of the stackhacks at the top of the forum in the 1.10 List of Hacks....anyone will do. Get a probe and type Alt + 1 so you can have him when u press 1. Then press F9 and wait for the lights to turn off then press 1 and start stacking.
If you don't understand it, tell me & I will try to make it more clear.
Good Luck!
