the problem is that the AI is inconsistent. some times it works with multiple outputs some times it doesn't. the only reliable designs i've seen are ones that just one output.I use mining drones with 40ish outputs and they seems to work fine until they reach the last 100 or so blocks on an asteroid. It's only then they have to pause and figure out what to shoot at.
I play on a server with fairly large sector sizes and I've never seen any issues mining. Perhaps we should bump up the default range of salvage arrays, that might alleviate some issues.I find that increasing the sector size and therefore the salvage range helps to avoid the miners stuttering. As far as outputs I notice it only really aims with one and the rest kind of fire off on their own and sometimes will brush across the asteroid but not reliably.
I on the other hand play on a server with fairly short salvager ranges...I play on a server with fairly large sector sizes and I've never seen any issues mining. Perhaps we should bump up the default range of salvage arrays, that might alleviate some issues.
