You’ve powered up the Tech Reborn grinder, fed it ore, but nothing happens. You’re not alone—this is a common issue with a few key culprits. Whether it’s the type of ore you’re using, a hidden energy shortfall, or a simple inventory backup, the fix might be closer than you think. Most players overlook one critical detail that stops the process dead.
Check Power Supply and Energy Needs
You’ll need at least ⚡1080 power for your Tech Reborn grinder to run properly, so make sure your energy source matches that requirement. Check that the grinder’s properly connected—any break in the connection kills the power supply. If it stops at 100%, the issue’s likely low stored energy. Keep an eye on power consumption; running too long can drain your supply faster than expected. Use batteries or generators to maintain a steady power supply. Don’t rely on inconsistent sources. A stable, strong feed keeps the grinder going without hiccups. Fixing your power supply isn’t just smart—it’s essential. You’ll avoid false completions and keep processing smooth. Stay ahead by monitoring and upgrading your setup early.
Confirm Which Materials Can Be Ground
While some materials seem interchangeable, only specific blocks can be processed in the Tech Reborn grinder. You’ll need to use ore blocks like iron, copper, and gold—not raw variants—for successful grinding. Since 1.17, raw ores don’t work, so make sure you’re mining the actual ore blocks. Use a silk touch pickaxe to collect them, as they won’t drop otherwise. The rock cutter can also grind ore blocks directly, boosting your yield. Feeding ore blocks into the industrial grinder triples ingot output, making it worth the effort. Always verify your mod and Minecraft version—compatibility issues sometimes block functionality. Stick to the right ore blocks, and your grinder will work just fine.
Adapt to 1.17+ Raw Ore Changes
Since Minecraft 1.17 changed ore drops, iron ore now yields raw iron instead of ingots, but the Tech Reborn industrial grinder won’t process raw ores. To grind iron effectively, you need to adapt your approach. Skip the raw form and focus on mining the actual ore block.
- Use a Silk Touch pickaxe to collect iron ore blocks
- Process full iron ore blocks instead of trying to grind raw iron
- Use a rock cutter first for triple output
- Feed the resulting drops into the industrial grinder for iron dust
This way, you work with the new raw mechanics while still maximizing yield.
Fix Grinding That Stalls at 100
If your grinder halts at 100%, check that you’re using compatible versions of Minecraft and Tech Reborn—older or mismatched builds often cause processing locks. You can’t grind raw iron ore directly; the grinder needs ore blocks, not raw variants. Instead, use a rock cutter on raw iron to get iron ore blocks, which process correctly and double your output. Placing raw ores leads to stalls at full progress. Always confirm you’re inputting proper blocks. If issues persist, verify your setup matches mod expectations. You’re likely one step away from fixing it—just switch to correct materials and you’ll keep production running smoothly.
Update to the Latest Mod Version
You’ll want to update to the latest version of Tech Reborn, as newer releases often fix bugs that could be causing your grinder to malfunction. Staying current guarantees you benefit from critical fixes and smoother gameplay.
- Check the mod’s GitHub for recent patches addressing the bug you’re facing.
- Verify Minecraft version compatibility—mismatches break mod functions.
- Review official documentation for changes in grinding mechanics after the update.
- Update your entire modpack to prevent dependency conflicts.
Don’t skip the update—doing so might leave you stuck with a broken grinder. Keeping everything current means fewer issues and more time mining efficiently.
Try the Rock Cutter If Ores Won’t Grind
The Industrial Grinder isn’t handling raw ores the way you expected, even after updating to the latest mod version. Don’t worry—try the Rock Cutter. It lets you mine ore blocks directly, just like a Silk Touch pickaxe. Instead of collecting raw ore, you’ll get the full ore block, which the Industrial Grinder *can* process. This workaround bypasses the grinder’s limitation with raw materials. Plus, grinding ore blocks often gives triple ingot yields, boosting efficiency. If ores won’t grind, switch to using the Rock Cutter during mining. You’ll save time and resources. It’s a simple strategy tweak that fixes the problem fast—no need to force raw ores into a system that won’t accept them.
Check Input and Output Access
While troubleshooting your Tech Reborn grinder, start by verifying its input and output access—misaligned sides can block material flow. You must check input and output access to guarantee materials move smoothly. Here’s how to fix it fast:
- Confirm side settings – Use a wrench to assign correct input and output faces.
- Clear full inventories – A backed-up output will halt operations.
- Test with valid ores – Some items won’t grind if unsupported.
- Update mod version – A bug or feature change might be causing the issue.
Fix these, and your grinder should run without a hitch.
Frequently Asked Questions
How to Power an Industrial Grinder in Minecraft?
You power an industrial grinder by connecting it to a compatible energy source like a generator or power grid. Just make sure it’s getting at least ⚡1080 power—then you’re all set to start grinding raw materials in no time.
How to Use a Tree Tap in Minecraft Tech Reborn?
You just right-click a rubber tree log with the Tree Tap, and it’ll collect sticky resin. Wait a few in-game days to tap again. Plant new saplings to keep your supply going. You can smelt the resin into rubber for crafting wires and machine parts.
