Vend Packager

Accumulates items and ejects only full stacks. Very convenient to use in the ore sorting system, instead of dozens of stackers and sorters.

you will need 1 Stacker, 1 Sorter, 1 Vending machine and IC housing with circuit for sure. After the Vending machine output slot put a stacker, followed by a sorter. Connect everything with chutes so that the side output of the sorter leads to input of the Vend and the main(right) output leads to where you will store full stacks (see the picture, the ore lies near the output slot for full stacks).
Set IC screws:
d0 - VendMachine
d1 - Sorter
d2 - Stacker
Done!

after a new item dropped into the Vending machine, it will wait 5 seconds (in case you drop several items at once) and start sorting.

By default, it automatically selects the maximum possible amount of items in the stack, but you can set your own amount - at the top of the script, change the AutoStackSize value to 0 and then set the desired amount on the stacker.
