In addition to the kit, you need to also consider how you will run/protect the wires. Some people use sleeving. Some people use cable chains. Some people use sleeving and the tape measure trick. And occasionally I see a machine using bare wire. V1 sells 3/8" sleeving in the shop. I don’t think 3/8" is big enough for the tape meausre trick. And the method for the Z axis does not have to match the X and Y axes.
