How to Make a Cobblestone Generator in Minecraft (4 Designs)

There are two types of resources in your Minecraft world – renewable and non-renewable. The non-renewable resources are the ones that cannot be artificially produced, while the renewable ones are farmable and can be multiplied. In this guide, we’ll focus on one very useful renewable block, which is cobblestone. We will show you how to make a cobblestone generator (or cobblestone farm) in the world of Minecraft. This will help you have an unlimited supply of cobblestone for all youramazing house builds.

What Is a Cobblestone Generator?

Cobblestone generator is a fancy name for a simple mechanic. Water and lava interacting with each other in their different states produce different results. Pouring flowing water over still lava sources creates obsidian, which you can mine with adiamond pickaxeand craft anenchanting tableormake a Nether portal. Flowing lava touching still water sources creates stone blocks.

And finally, flowing lava and flowing water together create cobblestone. Yeah, it’s that easy, but how you do automate this process?

Cobblestone generator is a controlled system that allows you to get infinite cobblestone blocks fairly conveniently. We’ll be taking a look at a stone generator as well in this guide, as it has an additional use.

You can either get cobblestone or stone from them, depending on thepickaxe enchantmentyou are using – silk touch for stone or fortune for cobblestone. Only the second type is a stone generator and the rest are exclusively cobblestone farms, so you won’t get stone from them.

Method 1: Simple Cobblestone Generator (Easiest)

As the title suggests, this is the simplest possible cobblestone farm to build. All you need is a bucket of water or a regular ice block and a bucket of lava.

And that’s it. New cobblestone blocks will continually generate in the middle, and you can keep breaking them. This is a simple little generator, that’s quite bad efficiency-wise. So, you got to be thinking right now, why did we even mention this simple and bad design here?

Well, in some cases, you don’t have access to more materials and resources. Take, for example, the skyblock map. To do anything else in this challenging map, you first need to build a simple cobble generator, so you can reach other islands and be able to make more progress.

Method 2: Most Popular Cobblestone Generator Design

This cobblestone generator is far better than the first one, but it’s also way more expensive. It’s a stone generator and includes a collection system using hoppers. To build this generator, you will need the following:

Once you have gathered all the resources, follow the steps below to make this generator:

Method 3: Piston-Based Cobblestone Generator

Now that we know and understand the basics of cobblestone and stone generators in Minecraft, let’s introduce a slightly more complex design. It consists of one or more cobblestone generators and the cobble is pushed toward the player using pistons. For this generator type, you’ll need the following items:

It’s up to you whether you want to build multiple modules. Here, we will show you how to build one module for your cobblestone farm:

This design can be further improved if you add a collection system of some sort under the pushed cobblestone blocks. You could also create multiple modules around your standing position, so you can keep rotating and breaking even more cobblestones.

But you will soon realize this is a slow machine, but it works reliably. In order to stop the machine, just activate the lever, as it will permanently power the piston.

Method 4: Fully Automated Cobblestone Generator

For this final cobblestone generator design in Minecraft, we will use an even faster machine and also add a TNT duper to it. It’s a simple but powerful redstone machine that lets you duplicate TNT. You cannot get TNT in item form but only as primed entities.

We’ll also include a famousYouTuber Etho‘s hopper clock for it. With this design, you don’t have to mine the blocks manually, because the explosions will take care of them and you can just collect the drops. This design is a little more expensive than the other ones, but its going to do the job perfectly. Everything you’ll need is listed below:

Once you collect the long list of items listed above, follow the steps below:

Now that we have a generator in place, let’s start building a simple TNT duper.

Now, we’re done with the TNT duper. Let’s jump straight into building an Etho hopper clock for it.

As soon as cobblestone generates, the observer will detect it and send a signal to the sticky pistons, which are going to pull the cobblestone blocks down. Then, after a short delay, regular pistons will push them forward, so the sticky pistons can continually pull the newly generated block down. This generator is fast and can break.

If the regular pistons reach their full push limit, the machine will start to malfunction and delete the lava above. So, make sure the pistons don’t reach their full push limit. A simple way to prevent this from happening is to deactivate the generator using the lever. If the lava gets deleted by the blocks, just refill it and the machine will function again.

And with that, we have reached the end of this guide. We have included four different cobblestone generator designs, so you can choose which one to build depending on the resources a hand. If you have never built this machine before, we recommend you try out the second design.

However, if you are experienced with those design, feel free to make the third or fourth cobblestone generator designs. With that said, what are you planning to do with all that cobblestone? Share with us and our readers in the comment section below!

The best cobblestone generator design is the fully automated one. It is rather expensive, but it will generate and collect cobblestone in the background, without you lifting a finger. Furthermore, the first design is the most iconic one and essential in the skyblock map.
