The Z axis will be counter balanced, probably with a gas strut, to offset the weight problem, but as it does drilling operations that want to have power.....big is beautiful too as inertia is a factor here.
Oh......... and you also need a power supply that's adequate, and then some, for the total package, skimping here is a total disaster waiting to happen.
