Troubleshoot Schematicannon Block Placement Failures

Why Blocks Won't Place

If your Schematicannon stops placing blocks mid-schematic, the most common cause is insufficient items in your inventory. This mod enforces inventory validation, so the cannon will halt if required materials are missing.

Diagnosing Placement Issues

1. Check your inventory — Open your inventory and verify you have all items the schematic needs

2. Review the schematic contents — Some blocks may contain items you didn't account for

3. Restock the Schematicannon — Add missing materials to its input buffer or your inventory

4. Restart placement — Resume the schematic from where it stopped

Prevention Tips

• Before starting a large schematic, gather extra materials as a buffer
• Use the Schematicannon's preview feature to identify which blocks will be placed
• Keep your inventory organized so you can quickly spot missing items
• If using container blocks, pre-gather all items that should go inside them

Normal Operation

Once you have sufficient materials, placement should proceed smoothly. The fix doesn't slow down the cannon—it only prevents placement when ingredients are genuinely missing.
