Hi Guys,
I'm a newbie. I have been saucing out the hardware that I require to build my first CNC Router.
I am confused regarding Acme square threaded rod. Can someone please explain to me what single,2 & 5 start rod is please. Which one do I buy.
My CNC router will measure 1.5 meters x 1.1 meters.

Thanks Guys
