Ensure robot wire anaconda doesn't tangle up

When offline programming in robot studio, how do you program to ensure that your robot anaconda doesn’t tangle up during motion? Or how do I validate/simulate that it isn’t?

Problem: I have a proper working program and I would like to mirror across the would Y axis, but I run into reachability issues, and errors when simulating the RAPID program.
Thanks for any advice

Thinking about using this add-in. Will it work in RS 5.61? Is it accurate when simulating?
