Troubleshoot Blocks Not Placing

Verify Schematic is Active

Confirm that your Litematica schematic is loaded and visible in the world. Open the Litematica menu and check that the schematic file is listed as active. If it's missing, reload it.

Check Printer Mode Status

Ensure the printer is actually toggled on. Press your configured keybind and look for visual confirmation (on-screen text, particle effects, or status indicator). If nothing happens, verify the keybind is correctly set in your controls.

Confirm Block Availability

The printer needs the required blocks in your inventory or nearby. Check that you have the blocks the schematic calls for. Some mods require blocks to be in a specific inventory slot or container.

Check Placement Range and Speed

If the printer is on but blocks aren't appearing, you may be too far away. Move closer to the schematic area. Also verify that printing speed isn't set to zero or extremely low.

Restart the Mod

If issues persist, toggle printer mode off and back on. If that doesn't work, reload your world or restart the game to reset the mod's state.
