Wanted to clean up my cube project

After a year, I have finally finished my 8 by cube. Learning alot about electronics and new software. My next task will be to make the controller board based on my schematic. It does work on a breadboard so my wife was real happy that I moved my "stuff" off the kitchen table! Trying to understand this auto route thing and keep getting nests that will not route in the final. Any help would be appreciated!
