Old guide, works, but doesn't do so consistently, which is what lead to my question.
Using a mix of tin and diamond cables across the mills themselves, and diamond cable linking to an MFE less than 20 blocks away. As I stated, some of the mills are working, I've had more than double the required number of buckets in the system and it doesn't help.
So the question is what could cause a water mill to fail to output power to a cable, despite being full of water (including being manually filled by hand) and yet the mill is still able to charge a tool manually placed into it?
