@lritter @kojack @sinbad Yup, that's the first struggle - to get a reliable enough power supply that you can leave it for 5 mins and it won't go poof. It's very important at that stage to switch off stuff you don't need.
That's one reason NOT to funnel materials into containers. I just use a moderately long conveyor instead. That way it will fill up with 20-30 items of the thing, and then the machine will back up, stop, AND STOP CHEWING POWER.
