DonutSMP Cobblestone Generator — Still Profitable in 2026?
Cobblestone generator on DonutSMP — yields, prices, whether still worth it in 2026.
Cobblestone generators are the OG passive income method on Minecraft survival. Are they still worth it on DonutSMP in 2026? Short answer: barely. Here's the math.
How they work
Water + Lava intersect → cobblestone forms. A piston pushes the cobblestone out, the cycle repeats. You stand nearby with a Fortune III pickaxe and mine the output.
Modern variants use redstone to mine automatically.
Realistic yield
| Setup | Cobblestone/hr |
|---|---|
| Manual mining | ~2,000 |
| Single auto-gen with piston | ~3,000 |
| Stacked 8-piston farm | ~15,000-25,000 |
| Industrial design (32+ pistons) | ~50,000-80,000 |
What cobblestone is worth
| Where | Price |
|---|---|
| /sell shop | 5 coins per cobblestone |
| /order | 8-12 coins per cobblestone |
| /sell as cobble blocks | 50 coins per block |
At 5 coins each (/sell), a stacked auto-gen producing 20k/hr = 100k coins/hour. Pretty terrible compared to spawners.
At 12 coins each (/order in bulk), 20k/hr = 240k coins/hour. Still mediocre.
When cobblestone IS worth it
- ✅ You're literally just starting (0 coins, 0 spawners)
- ✅ You like building redstone projects (fun > profit)
- ✅ You need cobblestone for your own builds + selling overflow
When it ISN'T worth it
- ❌ You have 100M+ coins
- ❌ You could buy a spawner for $0.49
- ❌ You'd rather earn 2M/hr from a Skeleton spawner than 100k/hr from cobble
The math vs alternatives
| Method | Setup cost | Coins/hr |
|---|---|---|
| Cobblestone gen | 1M coins | 100k-240k |
| Bamboo farm | 5M coins | 1-1.5M (10-15x better) |
| Skeleton spawner | 30M or $0.49 | 2-3M (10-30x better) |
Cobblestone is the worst per-hour method. Skip it for almost any other passive income.
The exception: building material
If you're building a massive base or megabuild, you need cobblestone as a material. A small cobble gen running while you're building saves you from mining manually.
This is the only good use case for cobble gens in 2026.
Industrial cobble farms
Some old-school players build massive automated cobble farms (32+ pistons). The output is impressive (50k+/hr), but:
- Setup time: 6-10 hours
- Setup cost: 100M+ in materials
- Total income: ~600k/hr
Still beaten by a single Iron Golem spawner. Skip industrial cobble farms.
Frequently Asked
Are auto-cobble farms allowed? Yes on most servers including DonutSMP.
Does Fortune III work on cobblestone? Yes — Fortune III on the pickaxe gives ~2.2x cobblestone per mine. Worth using.
Can I sell stone instead? Stone (smelted from cobble) sells for ~15 coins each on /order. Worth converting if you have a smelter farm.
Best cobble farm design in 2026? The standard 4-piston design with hopper collection. Anything more complex isn't worth the build time.
