Lava Farm Super Smelter Tutorial for Java 1.21 (and 1.17+)

[@RadicalElder]

Known Issues - Hoppers aren't really fast enough to make this work for a long period of time as intended. Items do back up. - Starting the farm up is easier with 4 junk items in the hopper that can't be smelted so you only need a couple buckets per furnace at first. - Lava cauldrons take 19 minutes on avg to fill up, there aren't enough cauldrons to constantly smelt using this. I am working on fixes and a v2 but honestly, building an actual endgame friendly lava super smelter runs into MULTIPLE challenges and may not be viable at all. This does work and I use it in both of my hardcore worlds (Twitch & YT) but the issues do exist.

[@lizzypotatoes]

Obviously use composters then, silly! 😜

[@AstaZora]

I actually see quite a few modifications that would solve most of these issues. From the top, the bucket collector can be simplified to feed the bucket back into dropper system. (the redstone block will bud power, and will break bedrock compatibility) Instead of a spinning cauldron design, a zigzag would work better. you could completely remove and fill a 10x10 area of cauldrons. Item storage is kind of messy but this is meant to be simple, so it works. This is a functional design, so I can't really be too critical on it. it works, it's easy to build for the average player, and it's not meant to be complex. For that, the issues presented are worth the functional design you've presented.

[@victorkirkwood1256]

What if you used a large kelp farm to feed the farm instead of lava? Added bonus if you keep the chunk loaded it will give you lots of extra fuel

[@RadicalElder]

​@@victorkirkwood1256 Kelp (and bamboo) are much, much laggier, especially when they get harvested. If you're chunkloading, it's very possible for you to be doing something "critical" to living and boom, lag spike just because, and you're dead. The "best" fuel is probably duped carpets. After that it's probably a tree farm turned into charcoal. Then lava, then bamboo & kelp, then actual coal. And I don't consider blaze rods actual fuel unless you are playing in a modded world with things like silk touch blaze spawners. You just can't get a really serious supply.

[@thechacorino]

This works on bedrock as well, just replace the solid block next to the piston with redstone dust and put the lever on the piston itself

[@RadicalElder]

I hadn't tested the other mechanics so I didn't list it for both yet but yeah, we made the lava farm work for both. I'll list it for both once I do a full test. Thanks!

[@NotForAnimals]

BRO came exactly for this, awesome tips.

[@justrosy5]

Are you in creative or survival mode? Also, which version?

[@justrosy5]

I tried this and it works the same for me either way (in creative mode, I haven't tried it in survival yet), because I put redstone dust all the way around the whole thing to connect all 4 corners. Thing is, I can't seem to get the hopper to drop the 16 buckets and dirt, then keep 6 buckets. Nothing happens there. How did you get that part to work? Edit: Nevermind. I had a comparator where I should have had a repeater. Fixed that and the hopper works just fine! Moving forward with the tutorial! Oh, also, Shulkercraft's way of doing the 4 corners works well in Bedrock, as does the way shown here. The way Shulkercraft shows it, you can have 4 ticks, the above way is crazy fast, so it depends on what speed you want, I guess. Anyway, the levers instead of the button works just fine in Bedrock. Haven't tried it with a button - don't see the need to at this point.

[@RadicalElder]

@@justrosy5 it should fire the comparator when you put something into the hopper behind it. then the dust, then the dropper

[@barbsfpv3066]

Fantastic tutorial man. My only minor suggestion is that you use a different block for your temporary blocks, than the main building block you’re using. That way it’s clear which blocks to remove as we’re following along and our attention is divided. I’ve been using Iskall’s multi-furnace array with a carpet duper instead of zero-tick bamboo farms, and I think I’m gonna try this one now instead. Thanks for the inspiration.

[@RadicalElder]

That's a good idea with the temp blocks. Maybe don't watch the shulker loader video (I used a hopper as a temp block lolololol)

[@ENDESGA]

okay legit, I was just sitting here - and the idea of a "auto filling lava bucket furnace" popped into my head.I thought it was original, but knew there's no way no one else has thought of this. I said aloud "surely someone has done this on youtube..." and searched. your video came up, and I'm so glad it's for 1.19 too. I'm very pleased to see you went way broader with the idea! I'll give this a shot, thank you! the internet is truly an amazing place

[@RadicalElder]

Haha I saw a few people had done "the other" (stacked dropper) versions of this and I was like cool but what if I just custom do a bit of a furnace array and feed into it and ... yeah! I use it for my hc world and it's honestly completely cracked. I love this for a mid to early late game smelter. Is it 300 furnace super mega array? nah ... but it's pretty mad.

[@ENDESGA]

@@RadicalElder hats off to you man for pulling this off! And cheers for the response! I’ve been so impressed by Cubicmetre’s work too, and I reckon this can fit into the rest of the auto system. I’ve always had the dream of the ultimate farm conglomerate that’s as dense as possible, and your work here helps me get closer to that goal 10-year-younger me dreamt of. Keep it up!

[@BrianCox2]

Great video. I appreciate how well you describe the build and also how you walk us through mistakes instead of ignoring them as some KZbinrs will do. I built this with some modifications because I did not leave enough space next to some of my other builds. One opportunity for improving your vids: give a layout of how much space this build will take before you begin and define where the features will be once built. Such as where the storage system will go. This helps builders plan out their space so they fit it around other builds.

[@RadicalElder]

Thanks for the advice and sorry about that. I've learned quite a bit since and am actually working on another tutorial for a tunnel bore now and I did remember to mention (and show) how big t he area needed to be to clear out for it. haha He can be taught!! Enjoy the lava smelter, too!

[@Rango-Tha-God]

absolutely brilliant design, i was looking into making my own furnace array coupled with a lava farm and decided to look it up, and voila, a vision even better than mine on yt! will be building this in my hardcore world. thank you!

[@RadicalElder]

I'm glad you like it and hope it works out well for you. My complications with it are listed in the pinned but other than that, it's a nice mid-game smelter. :)

[@Edaurd]

To solve the issue of the farm sometimes producing 2 buckets and you only receive 1 in a much simpler and more connected way, just have the dropper drop 2 buckets using an observer and using hoppers to pick up the excess and a dropper elevator to elevate the buckets back up into the dispenser,

[@RadicalElder]

Agreed, this would be one way to do this with a bit more work - I replied the same thing to Something Something's comments about an hour or 90 mins ago. I'll look into it - thanks!

[@cxbble3053]

Hey, I just built this smelter and realised there are some flaws. When smelting boxes of items, the collection system of cooked items will clock up really fast. Our hoppers underneath the furnaces were completely filled up since the hoppers can't keep up with the amount of items being cooked. Another flaw is the item distribution, if the hopper on top of the minecart is full, it will let the minecart always go. But the minecart can't take enough items to refill the furnaces because of that. I'd suggest trying a minecart to collect cooked items, if possible (I'll try to find my way around it). My fix for the distribution of items is, to activate the minecart manually, then using a detector rail which activates a small clock to give the minecart enough time to collect the raw materials.

[@RadicalElder]

Yeah there are a couple things I want to fix. The main ones are what you mentioned plus the fuel not being enough for 50 furnaces. Over time, sure, but if you want to smelt "boxes" at a time, it's not enough. After testing and using this for a few months I'd call it a great mid-game furnace but not endgame. I will build the end-game version soon, I hope!

[@cxbble3053]

@@RadicalElder it's a great by no means 😉 We just needed something to smelt, since we don't have a good way of getting lots of coal yet. My dumb friend just decided to smelt 4 boxes of cobblestone instead of just haste mining stone with a silk Touch😂

Glad to hear it worked out previously. It's a mixed bag - a bit hard to use lava in general but a solid design to do so imo. It's one of those "well it's maybe the best way to do this thing I wanna do" lol I have ideas for future iterations but we'll see ...

[@markgent6081]

This is an amazing design, well done. Although you would probably spend 50 hours smelting iron to save you a couple of hours long run. But it is fun and awesome

[@gaymerman3420]

you are very smart and i would have never been able to come up with the part of the farm you built, but the problem with it is that a bamboo powered smelter will just always be superior since bamboo grows so abundantly and its like the best smelter even if lava smelts 100 items

[@RadicalElder]

Bamboo smelters lag horribly compared to this so for people with lower end machines, this is the only way. On servers, this is the better way. And in singleplayer it's very compact and can hide away inside builds and not have to be covered with a build that's 25+ blocks tall. :) So it has its uses. Also if you want to smelt say 5 shulkers of smooth stone, the amount of bamboo in your farm will need to be huge. This will do it easily and with lava to spare.

[@DreamBlissYT]

Could you go into the card loading system in greater detail? Great video - thank you!

[@RadicalElder]

As far as how it works? It's a neat little unloader because of how simple it is. When the input hopper gets 23 items inside, it fires that redstone dust that goes into the repeater, while firing the "side" system which is that hopper/dropper clock. The hopper dropper block then powers the solid block and the dust, which turns the rail on and fires the cart off. The hopper passes the single item back and "resets" the system so it can happen again next time. The lever on the "inside" of that whole system just overrides all that and powers the rail directly in case you need to set it off without the hopper having "extra" in it.

[@DreamBlissYT]

@@RadicalElder Thank you!

[@PenguWattler]

I watched through once and intend to watch again but where and how do the furnaces get more lava buckets in them when a bucket is already there? How do the empty buckets come out of the furnaces? I know this is over a year after release but thank you for any response

[@RadicalElder]

So lava buckets go into the chest, up the water elevator, over into the chest near the top. The minecart grabs 5, distributes them to any hoppers that need it, and those hoppers feed the furnace. When it's used, the bucket is simply returned the same way as the output items, which is what leads to that filtered section that points into the dropper. So you get the empty buckets back and ready to use again. And I reply to every comment on my channel (so far) so no worries. haha

[@Daniel-rs4ll]

Hey! I want to start by saying thanks for sharing this cool construction. However I don't have need for such a big design and I'm wondering how small I could make this and still have it work? Would it be possible to do a compact version using say 20 furnaces (or even fewer), or would that be too constricting to be able to fit everything? If not, what could the issue(s) be?

[@RadicalElder]

You could definitely do fewer furnaces. End the rail wherever you want, above whichever hopper and furnace. I'd probably keep the main design and just remove furnaces but yeah it could do 10 if that's all you wanted.

[@Daniel-rs4ll]

@@RadicalElder That's good to know! I've just made your lava farm setup so I may upgrade it into the smelter. Having some kind of problem with the dispenser however. The cauldrons are moving around but the dispenser itself isn't doing anything. I thought I had to click the comparator to set off the dispenser but that did nothing. I also tried having the redstone and dispenser on different elevation without any progress. I'm sure that the solution is very simple but redstone is a mystery to me. Much like baking.

[@RadicalElder]

Dispenser? If you mean the dropper that gives you buckets back, it needs to be a dropper ( 4:25 ) so that could be the issue?

[@Daniel-rs4ll]

@@RadicalElder Solved it but opted to use the smelter with just the "conveyr belt" and no dropper as my needs are just not that high, but I really like the whole idea of a rotating cauldron system. Thanks again! :)

​@@RadicalElder thank you friend

[@hebrewash3882]

listen i may be the only one asking this but what do you mean by feel it all up like 300 buckets and idk where to put them

[@RadicalElder]

There are two ways to "fill" this system. The first is to put 4 "blocker" items into the fuel hoppers behind the furnaces ... that way you only need 2 buckets each to get it started (that's 1 in the furnace and 1 in the open hopper slot). The other way is to completely fill this with 1 in the furnace and 5 in the hopper behind. 6 lava per furnace times 50 furnaces is the 300 ... but I've been using the 1+1 so 100 these days. It's cheaper to get started. :)

This is a great design mate. I hope you can help me troubleshoot it if I goose it up haha!

Whelp it went amazingly! No major trouble shooting required. Only change I'd make in the future is use somthing like dirt for the temp blocks so they're easier to discern othet than that top notch guide with great perspectives and advice for how the build functions. Cheers my man

[@BreadPlays_]

I built this design in survival... The number of issues and adjustments I made was very frustrating. If you want to build this, I recommend you read my comment. _MAIN ISSUES_ LAVA BUCKET LOADING Problem: The lava buckets load up the first 8-10 hoppers and the rest of the farm does not get any. Fix: Fill each hopper (only the ones for loading furnaces with lava buckets) with four of any items that cannot be smelted. This will make it so that every furnace will have a lava bucket inside the furnace and a standby in the hopper that feeds it. UNLOADING SYSTEM Problem: The hoppers will fill up very quickly because the furnaces all smelt faster than hoppers can move items. This will cause a backlog and clog everything up. It also makes it so that buckets do not return because they are stuck in limbo never making it through the huge queue of items. Fix: My fix for this was using a hopper minecart that goes around the bottom of all furnaces. This works great HOWEVER you must use a very tricky method to deposit the items into the chests because if you do not you run into the same issue as before where the hoppers fill up and don't unload fast enough. The solution was to use 4 more hopper minecarts inside blocks clipped together in a complex unloader that takes all the contents from the main collector and deposit them into 9 different hoppers equally. STORAGE SYSTEM Problem: With all the adjustments made so far, there are bound to be lots of more unforeseen issues to come. One was the storage. Only using hoppers to transport the materials to chests was far too slow. A large backlog would appear which is a running theme in this build. Fix: below the depositing zone, set up droppers that throw all items out as fast as they can. From that, they drop into an item sorting system. This is important because it allows the bucket to be discerned from other materials. (Make sure to have a few overflow chests in case your machine starts to work overtime). LAVA CAULDRONS Problem: Once you get the whole machine working as efficiently as possible with the above fixes you will realize that you run out of lava far too fast. This is because each furnace takes two buckets at a time die the with the hopper holding on and the furnace holding one. Fix: You must make the cauldron loop much longer (I recommend twice as long). This can be tricky, but it is possible and allows for maximum efficiency. This design with these adjustments is amazing and works like a charm.

[@RadicalElder]

There's a lot that is correct here, which is why I've been busily working on a new version of this that fixes some of the existing problems. This version was meant to fill a void - there are NO good designs for a lava super smelter on YT so this one was that for a little while but yes the technicals aren't perfect here. LAVA BUCKET LOADING - Yes but also no. I just fill the sucker up completely. 300+ buckets, you're off and running. Your solution is a good one for the startup phase though and something I would probably recommend as it gets up and going if you need to immediately use it. Long term this thing makes more buckets than 99% of people will ever smelt through. UNLOADING & STORAGE SYSTEM - running 50 hoppers in a line is a mess, yep. The solution I will use in the future entirely fixes this but if you're in a rush this isn't the smelter to use anyways. I'm not trying to be the fastest, just use lava, power furnaces, let it rip. This does that but yes, unloading can take a while unfortunately. Using a very tricky redstone station to collect is possible but let's be honest, nobody makes the super technical stuff in survival or hardcore worlds because they can't follow it very well. This is MUCH more mainstream, just slower. LAVA - Again, turning corners and making extra changes is possible, it's just not a lot of fun for people who want to build a lava smelter in survival. A few of your solutions say "this is tricky but" and that's the recurring theme. THIS build is the simple and kinda slow version. The one I'm working on is a faster, more efficient version but that takes some technical work. Obviously here I just spammed in some furnaces around the already existing smelter design and feed them. So I would say there's a lot that is dead on correct in your assessment of this version's issues. It's just ... there is/was no fast alternative that kept things simple to build. V2 will fix: item distribution (much faster), item collection (much faster), lava collection (much larger, thus more available). Hopefully some of your workarounds help people in the meantime.

[@gaymerman3420]

howcome when im filling up the farm for the first use, some of the lava buckets just disappear like i would use 16 buckets and only like 3 of the furnaces are filled

The furnace fills, then the hoppers. So each one is 6 buckets before it moves on.

[@gaymerman3420]

@@RadicalElder ohhhh that makes sense nevermind

[@ethanzaczynski9293]

Would it be more efficient to turn off the cauldron chain and let them fill first? or have it constantly running? obviously one is more bucket intensive than the other, but aside from that, not sure if it affects the fill rate of the cauldrons

[@RadicalElder]

It doesn't affect fill rate very much. I turn it off most of the time because it's a bit loud, then I just run it when it's a bit more full unless I'm using it as a lava farm. Then I empty it, run it AFK for a bit, fill it back up and go again. :)

[@kortlendmoore7700]

Is there any chance I could get the dimensions of the farm? I've tried to figure it out by pausing but don't want to be wrong.

[@RadicalElder]

The build is 22x24 (24 is front to back) but including some of the additions more like 26 front to back. You'd want a couple blocks around it - safe to assume the build should have at least 24x28 and you'd at least be able to move around. 30x30 would give you MORE than plenty. If you put it indoors, give yourself 10 high for extra room from the cauldrons to the ceiling.

HI, ^^ just made it , i look to understand every part of your amazing farm, (really amazing) i have a question : what's the purpose of the lever behind the chest under the cauldrons? when i activate the farm, i understand that you activate the lever at the corner with no empty space with a double clic , that s ok, if i try to manipulate the lever behind the chest it's not make any change.

[@RadicalElder]

The hopper catches the buckets you throw and then puts them in the chest. The lever behind the chest locks the chest so you can "keep" lava buckets in there if you want. Maybe you are making my hoglin farm and want 50 buckets of lava - it won't go into the furnaces, it just stays beside you to use for other things than the furnace.

[@mysticnaeco]

The cart is Off, the double chest with hoppers refill with the double super light speed ^^ and when it's full, i did the same thing as you , put a comparator in the good way, a repetor and 2 redstone. A signal pass through the comparator and activate the redstone signal , the cart go to his purpose automaticaly, this is exactly like you , we are ok. ^o^ but just after that, The "Off" powered rail stay inactive But The redstone signal stay ON and i don't now why. Really i look at this video in 25% speed, 10 times since this morning and i don't know why the cart stop , refill but stay in place. it look like it's automatic in your video. Cart stop , refill and go alone . Mine is on strike ^o^ Thank you a lot for your response, your design is the angular piece to my huge automatic farm. I connect to the input a lot of automatic farms: chicken, porc, beef, lamb, potatoes, kelps, stone, sand, and in the output i use an Item Sorter

[@RadicalElder]

The cart loader is a bit strange. I'll tell you two ways to fix it: If the cart does not fill up +23 items in the hopper it won't send so you have to use the lever to send it yourself. If the cart does fill up and the hopper somehow fills MORE than 23, it won't send so take everything out of the hopper and let it start over from 0 and it will run automatically. One of those two things should fix your problem. :)

[@mysticnaeco]

Thank you so much for your patience and explanation ^^

[@cluver99]

But, the lava will need to fill up the corresponding hopper of each furnace to pass to the next furnace and do the same all over again right? So, the smelter to star to run efficiently will need a lot of time filling each and every hopper of lava?

[@RadicalElder]

Yeah what a lot of people have done when they build this is fill each of the hoppers that goes into the back of the furnaces with 4 non fuel items so each furnace only needs 1 lava bucket to get started. :)

[@VinhWin]

does the lava farm usually take awhile to fill up?

Yes the first time it takes a bit. You are filling 6 per furnace (furnace + 5 in hopper) so you need 300 to fill it. Then I recommend just collecting when you can like if you're doing a big smelt empty it out.

Bro, can you say when you will release V2? Approx date

I don't know - the concept is done but not the draft build and not a final build. It will still be a little while so I would use this one for now if you need a smelter.

[@somethingsomething9724]

you could just make the bucket dispenser spit out two instead of one, player in full inv with a stack of bucket don't pick up the extra one so you could just hook it up to go back to the empty bucket place, or the bucket dispenser....

[@somethingsomething9724]

i also thought you would put a system where the fuel source only activates once every hopper have one bucket of lava each, and then it releases giving the furnace fuel........

[@somethingsomething9724]

its just more convenient and better that way in my opinion

[@RadicalElder]

Shooting two would require you to have a dropper elevator under the entire system - a bit more complex for sure. It's a good idea for a possible V2 but it's probably even more technical. When we watched the premiere last night the common thread was "this looks hard" so I'm trying to simplify more than complicate. Fueling once every furnace only had one would be ideal but would require a lot more redstone inside the farm, as well. I think they're great ideas, but just complicating a farm that is more meant for everyone. There are more in depth systems out there for those who have more traditional fuel but I couldn't even find a lava smelter other than Mumbo's and a couple done in survival but no tutorials at all.

[@tatatatov]

The top minecart doesn't reload and unload fast enough. A lot of lava fuel is wasted in the time that it takes to reload every furnace. DO you have a fix for this? I tried to slow down the top minecart as much as I could but its still inefficiently burning the fuel

[@RadicalElder]

No this isn't really designed to be efficient and use every tick of the lava's burning capability. It's meant to keep you from spending coal with something renewable. OP coal smelters just require a whole tree farm or a wither skeleton farm in a perimeter or something to operate, which I didn't like.

You just need the speed to get around. It may take more redstone blocks if you swap some normal rails in.

[@addisonheggem6217]

Ok thank you

[@yuritarded2225]

where do you put the 300 buckets

[@RadicalElder]

As you use the farm, 50 will go to the furnaces, and 250 will sit behind in the hoppers. If you want to start it quicker you can always manually move 50 buckets into the furnaces first, otherwise it fills from the end. If you're filling it yourself, drop lava buckets into the chest over the lower rail - not the input chest for items but the other one next to it up top.

[@PurpleColonel]

Do all of those powered rails need to be powered for this to function?

[@RadicalElder]

No it just simplifies the build. Otherwise you need a bunch more redstone blocks or another way to power the movement. As long as they can get around that's all that matters.

[@PurpleColonel]

@@RadicalElder Alright, thank you! A few more questions I've been having since I built this... What does the lever beneath the one cauldron actually do? And why does it need 300 buckets rather than enough to fill the furnaces + the dropper?

[@RadicalElder]

If you flick the lever, the lava buckets stay in the chest and don't go to the top. This is useful when you need the smelter to act like a lava farm, not a lava super smelter. I say to start with 300 because that fills all furnaces (50) and all hoppers (5x50 = 250). You can then just collect more for the chest up top but that becomes backup. You don't *have* to have 300 to run it but it works best when starting with it full. I normally throw another 10-20 stacks of buckets in the dropper just to get started and that seems to keep it all working smoothly.

[@PurpleColonel]

No but make sure your comparator at the front of the redstone bit is on subtract mode. Lots of people make that mistake. If it is not loading, take everything from the cart and hoppers and chest. Is only one rail deactivated or two? If it's one, put all the items back in the chest and see when the hopper gets +23 items does it not power? That's a redstone problem and something is built wrong.

Empty out the input double chest and the hopper below. Also empty out the hopper minecart on the first rail. Break the hopper MC - is the rail under it dark? If so, the lever is in the right way. Flip the lever. Does it turn that rail on? Awesome. now turn it back off. From there, put the minecart back. Does your hopper/dropper clock have 1 item inside? If so, awesome. if you did the redstone properly, fill up the chest now. When the minecart is full and there are 23 items inside the hopper above it, the cart will leave the station.

Throw any item into the hopper in front of where you stand. If you put one in and the dropper doesn't fire one back at you, the redstone is somehow wrong on your end (or you're in Bedrock / MCPE)

@@RadicalElder Hey thanks for the fast reply! So I'm a little confused on which hopper you mean. So I'm in MC Java just to clear the up. I have the Dropper connected to the 3 hoppers like in the video and one hopper going into the comparator with 20 names blocks in stacks of 5 and then the 6 buckets. after the empty buckets stack in that hopper the move along to the dropper and just pile up there filling that dropper. Should that dropper be connected to anything else? Thank you so much in advanced for the help!

[@RadicalElder]

Pause at 5:49 in the video. See the hopper facing into the double chest behind the comparator? If you put one item in there - any item - the comparator should fire, triggering the redstone, which should send you a new bucket. So just toss anything - dirt or whatever, into that hopper. Your inventory should get +1 buckets if that section is setup right. Keep in mind the hopper is faced into the chest here, not that comparator. Hope it helps. If not, I go live in about 4 hours. Ask me to show you on my livestream at twitch dot tv / radicalelder

[@bossawesome33]

@@RadicalElder At 5:49 i am referencing the dropper on the right, just above and to the right of the quartz slabs. Thats where the empty buckets go and just pile up. I would love to come to the stream live but I'll be long asleep by then, (way different Time zone)

[@RadicalElder]

Yes, that's where the empty buckets should be. How the farm works is this: once you've built the whole thing, you fill your inventory except one stack of buckets. So you have 16. When you turn the pistons on, you'll hold down right click facing the cauldron in front of the hopper that goes into the chest. When a lava bucket gets picked up, it falls into the hopper in front of you. That should trigger the comparator to the right of the hopper, which triggers the redstone next to the dropper, which triggers the dropper to send you another bucket. You should start with 16 and after picking up the first lava, still have 16 buckets.

[@gaymerman3420]

wouldnt it make it use alot less buckets if you just fill 4 slots of all the that have the lava buckets with dirt

[@RadicalElder]

Yes, you can do that to get started for sure. I tend not to so I can use the hoppers as extra bucket storage. Short term filling them with dirt is better to get started. Longterm I always find my chests full of lava buckets.

[@winterisok]

Heyo I have a problem with the redstone signals that send the minecart back off to restock the items, once the hopper gets to 24 items. My problem however is that it does not go back out. Any Idea on what might be causing that?

[@RadicalElder]

Do you have one item in the clock that it's activating? It should activate that one item to go to the other side and then back - which powers then depowers the rail

[@winterisok]

@@RadicalElder By that I take it you mean the dispenser/hopper off to the right of the storage correct? Yes there is a block in it. When the minecart comes back it only stays if the powered rail is off, as its filling up the comparator is ticking, once the hopper reaches 24 it makes an audible click sound, which I assume is the signal to send the minecart on its way, but nothing happens

[@RadicalElder]

Is it a powered rail? When it hits 24 is it BEING powered? That's what should happen ... It sounds like some part has gone wrong with it for you. If you're on discord, ask in my "tech help" channel and I'm sure someone can tell you nearly instantly, if not me.

Most likely you have the hoppers facing with the point down not into the furnace. They need to be pointed into the back of each furnace (shift+click). Check the point of the hopper. Otherwise they should be going in if there's nothing in the furnace. No filters needed.

[@RadicalElder]

According to some of the commenters yes, "This works on bedrock as well, just replace the solid block next to the piston with redstone dust and put the lever on the piston itself" - that was their way of converting it and others said this fix worked. Haven't tested myself but it seems to, yes. All the mechanics should work.

[@AffanKarimullah]

When the minecart is full it wont go automatically

[@RadicalElder]

You can't fill the hopper - if the hopper above the minecart has more than 20 items, remove them all and put them back in the chest. It should leave after that. If it does not, you probably forgot the single item in the dropper/hopper clock.

[@legeeketlegamer]

why the farm don't work i use the litematica and the pston don't work fine

[@RadicalElder]

You have to find where the extra cauldron is and turn it off and on quickly. Make sure there are no other pistons extended in the way of the square before you start and then just *flickflick* two times quickly to make it start. If you are too slow the piston stays out and the next one can't move.

[@Pandaboi_13]

for some reason the dropper doesnt drop me a bucket

[@RadicalElder]

Throw an item into the hopper while looking at the comparator. Does it light up? item in hopper should light the comparator. That should power the block, which powers the dust, which fires the dropper. Something in there is wrong if putting one item in the hopper doesn't dispense one item from the dropper.

[@justrosy5]

This takes a ton more repeaters than are listed in the description. I didn't realize that until doing my modified build of this in Bedrock 1.19, survival mode, where I had to actually create this piece by piece, and couldn't just hit E in creative mode and get an instant stack of 64 that goes on eternally. Also, it uses more redstone torches, at least in Bedrock. I'm working on recording my build of this in Becrock's survival mode, after I got it functioning in Bedrock's creative mode. It's a real doozie! Very expensive.

[@RadicalElder]

It's not meant for bedrock so none of the redstone torches, etc. whatever numbers are even listed. The description says 4 repeaters. That's 2 near the soul sand for the clock, 1 on the item filter and 1 near the top right chest. It's correct. My item list isn't for the "tips" section and the advanced fixes. Most people who build it don't add all the extra functionality for full restocking. The required materials list is correct to build the smelter itself, which is what this video covers. Also, I have this working in bedrock. I don't know why it wouldn't work for you but it straight works for me. Unsure what you would be fixing other than the extras at the end of the video. I've built this in my hardcore YT and my hardcore Twitch world. I'm aware how it works ... comment seems ... idk. Out of place. Considering I'm 90% the way to producing a much improved V2 of this and fixing most of the common issues people have actually had, it would be a bit of a silly idea to reproduce a bedrock video of this when the idea is solid but the execution rightfully needed work. Reproducing this farm and not iterating on it would be incredibly shortsighted.

It's better than other renewable resources like bamboo because it's less laggy and better than blaze rods b/c you have to manually transport those.

If the cart isn't running because the cart is full AND the hopper has more than 1 stack in it, move everything in the hopper back to the chest and it will run automatically again.
