Looking for help making addition to found mining program

So i found this mining program that works great and the only problem i face with it is how the turtle places down a chest when it gets full then moves on without the chest, so when the program finishes i have to manually pickup all the items in the chest scattered around the hole. So what im asking for is a small addition/change to the program so the turtle places down a enderchest, put all the items into it, and pick it back up. also I'm using the crackpack mod pack with the turtles. Thanks

You can make the last 2 lines in the chestDump() function

turtle.select(1)
turtle.digUp()
chest = chest + 1

It works thanks for the help.
