If you are having issues with your duplicator, this may be because you have Spigot PaperMC installed and hence the piston duplication is set to false by default. You need to enable this to true.
Go to Paper MC config file and change
allow-piston-duplication: true
NOTE, for Minecraft 1.19+ PaperMC have relocated their paper config file.
For Minecraft Paper Spi-got v1.19+- Go to Control panel --> File Manger section
- Look for config/paper-global.yml file and edit it
- NOTE: This file is very sensitive to spaces. Don't add an extra space or line anywhere or it will break
- Look for: allow-piston-duplication: false and change the false part to true. (Careful not to add any extra spaces)
- Save the file by clicking on the Save button
- Restart server and your duplicator will work!
For Minecraft Paper Spi-got v1.18 or less- Go to Control panel --> File Manger section
- Look for paper.yml file and edit it
- NOTE: This file is very sensitive to spaces. Don't add an extra space or line anywhere or it will break
- Look for: allow-piston-duplication: false and change the false part to true. (Careful not to add any extra spaces)
- Save the file by clicking on the Save button
- Restart server and your duplicator will work!
