Particle press is not ingame anymore as far as i know. If you need L1 ore, you find X amount of it somewhere, and go shop. When you browse to that mineral you\'ll see a \"Buy recipe\" button, and can use that to craft the ore. But the materials to craft are always random, so if you buy it again, you get different recipe for same end result.
RECIPE_BLOCK_COST is the value X, in server.cfg.
