I’ve gotten to the point where I would like a Crusher so I can easily turn Ores into Crushed Ores without taking 10 minutes and tons of resources (hammers) to crush them manually. I have no idea how you’re supposed to power a Crusher with Steam power without needing ridiculous materials.
(i.e Steel everything)
The best I’ve gotten is something like this: Burning Box → Boiler → Turbine → Rotational Engine → Crusher
And that also seems to not produce enough KU to power the Crusher, at least consistently, because sometimes it works and sometimes it doesn’t.
