It doesn`t work like a proxy would and you just have to be patient with it

Path setting is easy but don`t expect it to actually follow that path continuesly because it depends on the mobs spawning. Sometimes it will stay in a certain area until absolutely no mobs spawn then other times it will do as you expect it to.
Path setting, click no to loading saved coords, then click ok then jump to a desired position then click ok again then jump again click ok again and try to make the "path" a circle route then when you get back to the original position you started then click cancel.
You can then save the coords and reuse them for that same area

Hope that has helped.
