Help with suspended jobs with Double Slit method
« on: April 14, 2020, 08:29:45 am »

Hello!

Thanks so much, I'm kind of new to Dwarf Fortress and I've gone through several forts and wanted to challenge myself by building on an aquifer. I've been trying to follow the double-slit method in the wiki and in this video (https://www.youtube.com/watch?v=yzdUw92pXH4) which are very helpful, the problem I'm having is understanding how to get any dwarf to actually build the wall. I've probably done it 50 times and each time the dwarf will suspend the job because the location is submerged. I read the forums and people keep talking about "unsuspending" the job which I don't understand, is it the same thing I'm doing, going into the job menu, canceling the suspended job and creating it again with b-->C-->w? Is there anything more to that? If there isn't then I'm sort of stuck and can't figure out how to get past the constant dwarf job suspensions unless there is no trick to this.

Thanks for the help!

You unsuspend from the jobs menu (you suspend/unsuspend with "s"). Cancelling and creating a new job to build the same wall from scratch throws away any progress you may have made. Many times the job is suspended again as soon as the dorf attempts to continue, but sometimes a little progress is made, so little by little you get there, but it takes a lot of attempts to get a wall segment in place.

I use two miners and have those being the only ones with construction and pump jobs enabled, to avoid someone from across the map take up the construction job.

Embark on aquifer is challenging so long you do not figure out "how". Location will be temporarily overflown with water.
You look at terrain with "q".
When you move over or close the wall, which is being constructed, you notice "suspended" in red text. You push "s" to unsuspend.
Then you move to other sections of the wall to check on progress.

Thanks, that helped a lot, I was cancelling the job and redoing it, once I just unsuspended it properly it went much faster. I'm still not 100% sure I understand the double slit but I'm still giving it a try.

There were two crucial pieces of information I had to understand to really get the method (note that these concerns the heavy aquifers. I'm unsure about 2 for the light ones):
1. Unlike regular water, aquifers do not leak diagonally.
2. A single, isolated aquifer tile absorbs and produces unlimited amounts of water.

It can also be noted that it IS possible to repair the situation if you screw up on the 3:rd slot on the lowest level (which typically shows itself by water not being absorbed when pumping from the fourth one). In that situation you have to reverse the pump, pump out 3 and remove a wall tile you've built (to get a sink), reverse the pump, treat 4 the way you should have treated 3 (i.e. with an isolated aquifer tile), reverse the pump, pump out 3 and restore the wall tile, and then channel out the isolated aquifer tile in 4 the way you should have done to 3.

This "looking" part is so annoying and the method in standard edition is not producing the favored by me 3x3 stairs.
So my solution is 3/6 pumps. You bite it from 2 sides of stairs at once or one side at a time. It never matters if there is water or not on last level of aquifer. You will always get water from the central location to sides. I was making wells in stairs this way, but it needs some further modification I think, as you need 2 lvls of water.

If by the "looking part" you mean looking for a damp floor, you don't have to do that. Just check the material and either consult your memory of the wiki to determine if it's aquifer bearing or not.

Sure, you can widen the aquifer staircase, at the cost of a fair bit of extra labor. Not something to recommend to someone just starting to get to grips with heavy aquifers, though. The basics are complicated enough.

In heavy aquifer, when you have 2-3 pumps on job instead of 1, then you can avoid any possible casualties, when pumping Dwarf suddenly leaves the job. In my first dig through aquifer, I was using the "simple" method and I lost 3 Dwarves learning it. Never used it again. I always will suggest use of 2-3 pumps instead of 1. Safety in numbers. :D
