FAQ and Common Problems

Frequently Asked Questions

Where can I download this mod?

It's not a mod, it's ComputerCraft Lua code. It needs at least Mekanism 1.10, which is first available on Minecraft 1.16.5. CC: Tweaked on 1.16.5 and later will work. Follow the setup guides on this Wiki or YouTube for what to do next.

What version of Minecraft do I need?

Mekanism 10.1 came out for Minecraft 1.16.5, which has CC: Tweaked builds 1.97.0 through 1.101.3. I recommend using at least CC: Tweaked 1.101.3. Any Minecraft versions after 1.16.5 with any newer versions of those two mods will work!

Common Problems

My computers won't connect to each other!

This is always caused by one of the following:

1. Use of Wireless Modems rather than Ender Modems. Wireless Modems have limited range, so I always recommend using Ender Modems.
2. Wrong channels. All network channels with the same name must match across all devices in your network.
3. Trusted range is too short. Trusted ranges should either be zero to disable the functionality, or set large enough that all your devices can talk to each other.
4. Facility authentication keys don't match. Facility authentication keys need to be set on all or none of the devices in the network. If set, they need to all match. Please double check them.
5. Communication protocol versions don't match. If you see a yellow network light (or a lit NT VERSION light in color accessibility modes), then make sure all your devices on your network are up-to-date. Use ccmsi update <app> to update your app (such as ccmsi update supervisor on the supervisor).

There are specific cases as well (usually apply after things had been previously working, or some did connect):

1. PLC's with the same reactor unit ID will not connect if another PLC with that ID is already connected. Make sure you only have one PLC configured per reactor.
2. Devices with different communications protocol versions (can occur if not all devices are up-to-date) will not be able to talk to each other. Make sure devices are up-to-date.
