I just did this a few days ago in my own volcano fortress and it is simpler than you showed. You don't need to hook up the bridge to anything at all, just block the topside of the ramp with it, leave it closed, and you can designate the volcano wall to be dug by the miners and they will mine it through the closed bridge. Not a single lever or mechanism is required.
Need to try this because the method in the video caused the miner to cancel the dig. Maybe this was recently patched I have no idea. Update: Yeah, just digging straight through the bridge from the ramp below it worked for me too.
I know it used to work this way for a long time, but last time I tried it didn't. I'm guessing I've just done the ramp wrong + maybe the bridge type really matters.
@@lubomirkompis9441 It works I was playing a fort again the other day and did this again. Maybe try channeling 2 tiles in a row away from the volcano and multiple tiles wide? I channeled a 2x4 area by the wall of the volcano, with 4 being parallel to the wall, 2 being perpendicular, that created ramps that went up at the wall of the volcano.
Ugh. The "no unpassable tile in workshops" really got me by surprise, I set up my forges and smelters like usual and suddenly found a whole army of magma crabs on the forge level covering everything in magma spit a few years later. Had to order my military there to clean up the buggers, deconstruct a couple smelters and crack a nearby water reservoir to obsidian cast the channel under them. Good thing there was water around, I remember ponds not working properly for obsidian casting purposes and didn't want to risk it.
Note that when making the bridges you need a second access point - that's why there is a constructed wall next to the bridge. You need to close this access point before you give the mining command.
You could always make a filter with some magma proof vertical bars (built with construction I want to say) and put them on the opposite side of your bridge / floodgate /etc. I do that for all my water projects.
and fortifications can be passed trough when submerged. But creatures can't destroy buildings from below (I don't know if they can with ramps but just makes sure there isn't one) so a grate with pressure pushing the liquid to the level of the grate will be safe from creatures.
I'm 95% sure that you can't build a smelter on a floorgrate as they're both buildings, but I haven't tried in version 50 yet. I'll give it a go during my next stream Update: Yeah this still doesn't work - you get a "building present" message when building on a floor grate.
If it works with mining, then I'd assume it works with making fortifications (smooth the wall first, then turn into fortification with the bridge down). Then you won't need the second bridge since the mobs can't crawl through the fortification. Also, instead of building the snaking corridor, just stick the miners in a squad and station them far away to buy the time.
I know its have been like ayear after this video was posted. But i have a question, will this setup work the same way if the we change the lava into a lake?
Great guide ty. I am having problems with my Dwarves falling into the magma that is under my smelters/forges. I dont know how, but i have lost a few dwarves and cannot find them anywhere on the map, no bones, no trace. Also when i memoralized a slab, there was no info on how the dwarf died. Could it be the forges/smelters?
It could be, Dwarves can be knocked into another tile when another passes through. You could try spacing out your forges and setting restricted traffic on tiles next to the opening to minimise how often Dwarves could bump into someone.
can you use a Fortification instead of the 2nd Bridge? or a Magma safe wall Grate? I haven't used Magma much yet. What are the dangers from Magma? I seen the Crabs in the Lava, but is there anything else??
Currently there's a bug where those don't block creatures when at 7/7. Some forgotten beasts, clowns and similar can be magma immune and could potentially path through the magma if they can get inside.
@@FurtherReadingTV how about Engraving Fortifications?I did notice that making Fortifications are not as high as a normal wall for some reason. would the Wall Grate work?
is there any reason you can't use floor hatches instead of a bridge to forbid access to the reservoir layer? edit: for breaching, not preventing magma creatures from entering
Very interesting! Now when you say that you'll want to make the magma tube more than 1 wide. Would you instead put 2 or 3 separate 1 wide magma tubes or will the dwarf be able to exploit dig through the bridge if it's a single tube 2 or 3 tiles wide?
You'd need one dwarf per square you're mining. The timing can be a bit tricky depending on how big your miner corp is but a 2-4 tile wide opening should go fine.
I Just carve a filter wall, no need to Bridges and mechanisms. And i Just shove from the workshop lvl in front of the filter wall, let the magma Fill the reservoir under my workshops and never bother with It again

You say exploit, I say precision dwarven engineering.

Vertical bars can be broken by building destroyers.

why not smooth the wall leading to the magma chamber and then carve a fortification?
There's a bug where a 7/7 submerged fortification won't block creatures anymore.
@@FurtherReadingTV I see
couldn't you just have a floor grate that the lava poors through to get into the reservoir?
Thanks this is very handy. I lost about 6 dwarves trying to make a magma reservoir just recently so I'll do this in future 😁
Could you use a floor grate under each smelter, instead of the 2nd bridge?
I'm 95% sure that you can't build a smelter on a floorgrate as they're both buildings, but I haven't tried in version 50 yet. I'll give it a go during my next stream
Update: Yeah this still doesn't work - you get a "building present" message when building on a floor grate.
@@FurtherReadingTV Can confirm, tried myself.
would pairing this with a magma U bend work to be able to use floor grates before the reservoir thus blocking building destroyers?
Yup that would work. You'd need to use a screwpump to pump it out of the grate since magma doesn't naturally rise up through u-bends though.
Absolutely perfect timing for me on a volcano embark without my magma smelters up yet.
Just get some nether cap wood on embark and make a corkscrew and pipe section. and pump it.
If it works with mining, then I'd assume it works with making fortifications (smooth the wall first, then turn into fortification with the bridge down). Then you won't need the second bridge since the mobs can't crawl through the fortification. Also, instead of building the snaking corridor, just stick the miners in a squad and station them far away to buy the time.
There's a bug where mobs can pass through a fortification if it's submerged 7/7, so you have to use the bridge as a blocker.
I know its have been like ayear after this video was posted. But i have a question, will this setup work the same way if the we change the lava into a lake?
Yup! I use it all the time for cutting into rivers and lakes.

Since all workshop tiles are now passable, i wonder i creature can dodge into the magma hole.
They can! It's happened to me a bunch 😢
Never had dwarves fall through my workshops

Nope, anything that lets liquid through can end up letting creatures through at 7/7 depth. :(
Why not use a wall grate or a flood gate instead of a bridge?
Building destroyers will tear them down.
@@FurtherReadingTV Man, what the point of grates then?
I wish you didn't delete the old video. A lot of people don't like using exploits.
Loving your videos. Would be really great if you could do one on obsidian farming.
Thanks!

I've never tried it! I expect it could work.

If by filter wall you mean a fortification - those are bugged and will allow swim throughs when at 7/7
wow thats awesome
