Make a fabricator based off a reed farm or cobblegen and get infinite stuff. It's really easy to have infinite everything within a few hours. Get to the nether, get what you need for magic chalk, then make fabricators. Do not delay.
High-speed essence loops are your next natural evolution. One of the best we discovered was fabricating bricks, running them through a pulverizer (fed by a stirling engine using fabricated charcoal, naturally) to make cracked bricks, then feed the cracked bricks back in. You'll max things out fast even with the updates to cause fabricators to have brutal deficit.
