Hmmm, there's only a few steps. Create a zone with (i), make sure its type is garbage dump. Then mark rocks with dbd.
Have you messed with the o)rders menu? Do your dwarves have hauling stone labor enabled? Have you created any burrows? Can the dwarves path to the garbage zone?
After marking the rocks with d-b-d are you hitting ESC to exit the menu?
Yes they have hauling stones enabled through therapist.
I dont make burrows because I still suck at them and even watching the Burrow Tutorial on youtube, when im done with the burrow, I have to delete the burrow every time because I cant seem to make them stop going to the burrow.
Yes they can path to the garbage 1x1 zone.
Yes I am using the Esc key.
