Hello, I am new to this forum and to cnc/milling and am looking to get into it as a hobby but currently know very little.

Sorry if this is in the wrong section (please move it if it is) but I am looking to convert a vertical milling machine to cnc (in order to hopefuly save money) but I have no idea what parts are needed.

I have tried researching this but there are so many different things and I see some cnc conversion kits for around $500 while other are closer to $2000.. Plus then there is software, etc.

So this is what I was wondering, If I were to make a checklist of everything I would need to buy to convert a milling machine to cnc, what would it consist of? And what would it cost (approximately)?

The milling machine I am looking to buy is this:
Milling/Drill Machine - Milling and Drilling Machines - Power Drills - 2AC40 : Grainger Industrial Supply

Thanks for any help!!
