If you want a slime farm on Donut SMP that is small, reliable, and actually worth AFKing, this setup is a strong option. We rebuilt the earlier version after running into the usual problems: slimes getting stuck, output dropping from mob stacking, and random armadillo losses over time.

After testing the new layout for one hour, the results were strong enough to call it what it is: a real money printer. It is not perfect yet, but it already makes excellent Donut SMP Money, and more importantly, it is practical to build and easy to improve.

↖ Why This Version Works Better

The biggest issue with the old farm was consistency. Sometimes it worked, sometimes mobs got stuck in corners, and sometimes rates dipped for no obvious reason.

This version fixes that by simplifying the flow and spreading the load better.

In practice, this means the farm stays cleaner and keeps spawning instead of choking on its own mobs.

↖ Build Setup

The footprint is surprisingly small for the amount of money it can make, but preparation still matters.

↖ What we did first

• Bred a good number of armadillos before building
• Kept 2 extras in a safe chunk as backup
• Dug the farm down to bedrock
• Filled nearby cave space to keep the area controlled

That backup step is worth stressing. In real survival gameplay, mobs disappear, die, or get misplaced more often than people admit. Keeping reserve armadillos saves a lot of time later.

↖ How the Farm Works

The system is simple once everything is in place:

• Armadillos are placed in four separate spots
• Slimes generate and fall into the kill area
• The lower chamber handles cleanup
• Drops are crafted into slime blocks for storage and selling

The main advantage here is speed. A compact farm only works if mobs die fast enough to free space for new spawns. That is what this design does well.

↖ One-Hour Profit Test

We AFK tested the farm for one full hour to get a realistic number instead of guessing from short bursts.

↖ Test result

The farm produced close to 4 shulker boxes of output in one hour.

That is the key reason this build stands out. Even using the lower estimate, it still lands in 60M+ per day range if prices stay stable.

↖ What Still Needs Improvement

The farm is strong, but testing showed a few weak points.

This matters because a farm can look busy while still underperforming. If mobs are too packed together, new spawns can slow down.

↖ Practical Tips From Testing

These are the details that made the biggest difference for us:

• Keep backup armadillos in another chunk
• Test for one full hour, not five minutes
• Watch for stacked mobs, not just total mob count
• Fix cleanup speed first before trying to add more production
• Use better storage early if you plan to AFK long sessions

If you notice rates dropping after a while, the problem is usually not spawn potential. It is usually that the farm is no longer clearing mobs efficiently.

↖ Slime Farm vs Bone Meal Farm

If your goal is pure profit, slime wins easily. If you want something simpler and more utility-focused, a bone meal farm is still a good option.

A strong moss-based bone meal farm can still be valuable, especially in vanilla or on servers where you want a low-maintenance setup. But for Donut SMP economy grinding, slime is the better play.

↖ FAQ

↖ How much can this slime farm make on Donut SMP?

From our one-hour test, about 2.8M to 3.7M per hour, depending on slime sell price.

↖ Why use four chunks?

Because it helps reduce mob congestion and keeps the farm more stable during longer AFK sessions.

↖ Should we keep extra armadillos?

Yes. If you lose a few, having backups in another chunk makes recovery easy.

↖ Is the farm fully optimized?

Not yet. It is already very profitable, but there is still room to improve mob spacing and potion coverage.

↖ Final Thoughts

This is the kind of farm that feels good in real survival play because it is compact, profitable, and realistic to maintain. The numbers are strong, the layout is manageable, and the weak points are clear enough to improve without rebuilding everything.

For Donut SMP, that is the sweet spot: a farm that already prints money now, with enough headroom to get even better later.
