You'll be using a software called Mach3 most likely. Just about any desktop and most laptops manufactured in the last 5 years will work fine. The best deals for used computers are found on eBay and craigslist. As for the BOB, I don't know anymore. I once used Axxus BOBs, but they are no longer in business.

To get better answers, ask this question in the Mach related part of the forum found here: Mach Software (ArtSoft software) - CNCzone.com-The Largest Machinist Community on the net!

I use a 1Ghz PIII from Ebay for $20.

But I'd recommend something closer to 2Ghz, Pentium 4. Should be around $100-$150 used.

It should be fine.

However.

I'm not going to guarantee that it will work perfectly with Mach3. The vast majority of PC's have no problems with Mach3, but from what I've heard, 2%-3% of PC's have trouble with Mach3.But more than likely, it should work well for you.

One thing to consider is that, ideally, you want a clean install of Windows, with no other software installed. If it's not a clean install, you may want to remove and re-install XP. If so, make sure you have the OS CD.

[paulkane1]

thanks a lot for your quick response , but can you please clarify 2 points for me , what do you mean by a clean install ? what will i asked the seller of the computer, and why is it important to have the OS CD ?. i am sorry if i am sounding not very bright on these matters, but i hope that you will be patient with me , i just want to get it right first time.

If there's a lot of software on the machine, there could be things that can interfere with Mach3 operation. Quicktime is a notorious one. Many programs leave processes running in the background.
Ideally, you want a clean installation of windows. Meaning re-format the drive, put the CD in, and install XP from scratch.

your a gentleman, thanks a lot , for your quick response.
