Explain your idea

I've built a moving contraption by combining Immersive Engineering and Create using a Create addon mod that has an EF/IE compatible electric motor. The problem is when the contraption moves the wire and connector break. This is 1.19.2 current available version. Is it possible to get either a stretchy line set that doesn't break, or a reel system for extensible wires?

I'm aware, but that's also the problem, and a simple solution would be to have reel wire that can move without breaking, or a wireless IE energy transmitter and receiver.

IE's blocks are not designed to be moved by Create.

You can't just "have a wire that moves without breaking". Don't tell me about a "simple solution" when you obviously have zero idea of our codebase.

Blocks were not meant to move. (Yes, blah blah, vanilla pistons. They can't move BlockEntities, and there's good reason for that).
Create does incredibly hacky shit to make it happen, and the effort for us to be compatible with that is not worth it.

So won't even consider adding a wireless FE transmitter, akin to the wireless redstone emitters?

No absolutely not.
I'm locking this conversation at this point.
