Just use an advanced regulator from gregtech to put the right items in the correct amounts in the required slots, works perfectly, fully automate-able, no cheating by changing settings in files required, no need for dummy items or full stacks.
Example: set "bedrock shaft unit" 1 pcs in slot 4 and "mount" 1 pcs in slot 7, stick an export bus to the bottom and place the work table on the red side -> Automatic Bedrock shaft maker. The regulator will always try to keep slots 4 and 7 filled with exactly 1 of the correct item each. Remember that you have to stick a conveyor module to the regulator and click that with a screwdriver in order for it to accept items from an ae (precision-)export bus.
