How does the Stone Press work?

What ratio does it want?

The printed cycle is 1 kg of dust and 1 kg of sand in, 2 kg of stone out, every 6 seconds. Holds on the building are 12 kg dust, 12 kg sand, and 10 kg of finished stone. Three belt connections match the two inputs and one output. Footprint is 9.26 by 6.44 meters and 6.14 meters tall, on the Production tab. One chamber making sand is described as feeding 2.5 presses, because the chamber's 5 kg of dust every 12 seconds becomes sand slower than five presses would eat it. I treat 2.5 as that page's arithmetic, not a law I measured.

PlayerEcho distinguishes a theoretical block of two chambers and five presses from a practical block of one chamber and two presses. With the published cycles, one chamber supplies 25 kg of sand per minute and two presses consume 20 kg, leaving a 5 kg/min sand buffer. These layouts change spare throughput; they do not change the press recipe. Check supply, power and belt routing when a buffer grows, rather than treating that symptom as evidence of a different recipe.

Is the press worth the power?

Stone at 7 times dust versus sand at 3 times is the value gap the page uses to justify 18 kW. It also sketches 600 blocks an hour, called 1,200 kg, and about $8,400, with roughly $6,000 an hour over selling the inputs. Those hourly dollars are the wiki's multiplication, one source, so I label them as that page's math. The 18 kW is the figure I would budget panels around: trackers at 16 kW do not cover a press alone, and a post at 3 kW is a rounding error next to it. Upgrades exist as a search topic, but this row does not list upgrade steps or their prices, so I leave the upgrade column empty.
