EDIT: THIS DOESN'T WORK ANYMORE
Behavior of changing modules changed on 2.0.17 so playing around with the beacons won't work anymore https://forums.factorio.com/viewtopic.php?f=11&t=120270

- Set the recipe in the midle and all in with quality modules
- Set the constant combinator with the desired quantity of your target item
NB! If you change the assembler, be sure to connect the green wire to the input inserter AND the outside power pole. Set working signal to W
Beacons will activate only after the machine starts working (after the quality roll) ensuring you have the best change to get higher quality AND the fastest possible crafting time.
For maximum performance, make sure to have quality quality modules followed by quality assembler, quality speed module and quality beacons.
