I'm trying to get a new wheel built up and i cant work these spoke calculators properly (stupid i know)

The build is a Deore rear hub onto a 24" sun MTX rim 32 hole, this is for a big hit and i think they have a zero dish rear wheel also this is going to be a 3X build

Does this mean that they have to have some different lenght spokes on one side?

Also i dont care about what you have to say about hub and rim choices
