DF Dwarf Mode Discussion / Impulse Ramp Minecart Magma Loader (No Power!)
« on: June 19, 2013, 05:35:44 pm »
I especially designed this for a minecart in wheelbarrow magma transport system, so you can get magma workshops really early without having to setup a bunch of power reactors.
The key to the system is keeping the magma level low on the exit impulse ramps so they can accelerate the minecart out of the trench without excessive friction, but still have the magma level high where you're trying to load the cart.
Legend:
s - track stop
b - retracting bridge over impulse ramp
R - impulse ramp
p - pressure plates
d - door
w - wall
X - raising bridge, into wall
. - open space
M - magma
Hopefully the bad ascii art is clear enough. The working bits are: a pressure plate set to 7/7 magma (top one) to trigger the retracting bridge, to launch minecarts. The pressure plate set to open the door when a minecart goes through, and a drawbridge connected to the same plate to get rid of extra magma. The one space gap is critical, when I had the pressure plate next to the door the minecarts just stopped.
The minecarts will make a quantum stack just next to the minecart stop if the magma is not full. When testing with 4 minecarts in a situation where they all end up stacked, they all to exit properly, however only 3 of them got filled. Make sure you have enough room store your minecarts after the exit so they dont back up into the lava.
In practice, you'll want the filled minecarts to end up sitting on a stockpile, so you can use give/take orders to get them where you want (be sure to use wheelbarrows in the taking piles!!) the easiest way to dump these minecarts is to setup 2 track stops right next to each other, both with dumping orders, and 2 stockpiles, one next to the first stop set to only take from links and use wheelbarrows, and one next to the 2nd stop. Setup a route with a stop on the first stop, set to take from the first stop's link only pile. When a filled minecart is delivered, it will be placed into the route's (wood ok!) minecart and dumped right away onto the second stop, which will dump the magma out! Then a dwarf will show up and place the minecart into the 2nd pile's stockpile, since it's the closest matching stockpile. Then send the cart back down to the depths!
It would also be fairly straight forward to setup an automated system, if you make the first stop dump onto an impulse ramp, and use a lowest friction stop for the magma dumping. Then route the track to a dropshaft to load them back into the magma loader, would only need dwarfs for the upwards route. You could even setup pressure plates to sense the magma level and turn off the magma dumping track stops to have a multi point distribution system. But that's not really on the topic of no power magma loading is it?
I'm going to see if I can make one using the "Moses effect" to clear the lifting ramp that will work with (intermittent) dwarf power, for a simpler starter system. It didn't work very well.
