Indeed, auto-dump stops can only dump everything. Manual dumping is for dorfs to do. depending on how you set it up, it can take just a few moments, the only problem being that wood doesn't use barrels or bins, so the stock piles would have to be large. The quicker method is to use a single dump stop, and have the individual stockpiles all set to take those types of wood from the auto-dumped stop. The quickest way to get the wood out is to make the auto-dump not actually be a stockpile for wood.
I imagined so, I was thinking about setting a wood stockpile on the surface and a small track that will dump all the wood through a hole in the ground into my fortress...
but I also want it sorted by wood type, each on its own quantum stockpile, after I get it inside in the quantum stockpile with all the woods I was thinking of setting up individual tracks to pick one type of wood and dump it further down another hole on its type specific wood stockpile...
Here is where things get kind of messy, setting up 31 mini tracks all picking a particular type of wood from the same quantum stockpile, so the wood types can be dumped in their individual holes...
I was thinking in a way to simplify this... and wondered can I set up more than one
route to use the same track system? for instance, a Willow route, with it's own cart assigned that will only pick up willow logs from the quantum wood stockpile, then auto-dump in one of the stops along the route and skip the stops that don't belong to that route?
or the moment it goes by the first auto-dump track stop, even if it's not part of that route will it auto-dump anyway?
Edit: just tested this, the moment the mine cart steps on an auto-dump track stop it dumps everything even if the stop is not on the specified route...
as a matter of fact you can set-up a route with only 1 stop where it picks up stuff from a stockpile, then push it, and have it auto-dump on another stop (without designating the dumping stop in the routes menu), it seems it's only required for when you want dwarves manually unloading the cart into another stockpile (what's the fun on that!
)
so it seems the only way is to set-up 31 mini tracks...
Is there a non-manual (dwarf labour) way to fill a mine cart? like dropping items through a hole which has a mine cart at the bottom...
