combining both the "turn green circuit back to voidtronic circuits" recipe and the basic voidtronic adaptation recipe with productivity (an electromagnetic plant, or prod modules) and starting with quality circuits allows you to infinitely create legendary quality voidtronic circuits -- and by extension, green/red/blue circuits, copper, iron, glass, plastic, carbon, circuit scrap, sulfur, and void shards.
this seems intended at least with the normal quality loop - but since this works with legendary, I don't see much point to chasing through the ascension orb recipes when i can do this with just 2 machines and no modules, as it circumvents most of the point of doing that
due to it seeming intended, could i maybe suggest making the output from the "green circuit->voidtronic circuit" recipe be always normal quality, or perhaps a single quality step down (so that purple quality circuits makes blue quality voidtronics)
