Hi,

I've seen belt drive, ballscrew, rack and pinion, but what about chain ? Guys at build-your-cnc use chain drive.

For a large steel CNC, would chain drive be a possible option, at least on X and Y, considering using a large chain (like those found on dirtbikes.

Would belt drive be an alternative ? If yes, which type of belt would you use for a 2x1.5x0.3m work area ?

And if all else fails, what is the cheapest drive system you could use on such a work area ?

Thanks a lot for your help !
