eBay CNC 3axis kit

[Jyman]

Ok maybe someone can give me a little guidance, I'm looking at building a cheap CNC router as this is my first one, I have an idea where to get most of the parts except for the driver, steppers, power supply. Is something like this a good item to start out with??

Some help in this area would be greatly appreciated.

If you know what you need you could probably do better but it's not a bad price if shipping is indeed free.
I picked up the same steppers for $25US each when I was in Phoenix. You could get a power supply for $40C from China, add in the driver board and you're likely in th$150C range. But then you have to fit it all together.

Hey johnwa,

Thank you for your input, I personally don't know what I need as this is my first CNC build. Is there anything else I should be looking at to go with that kit?

You said you bought the same steppers, how big of machine do you have? Would that kit be stong enough for my milling machine (grizzly g0704 mill, basically the same as a cx601 from busy bee) to convert it?

I am working on an X2 minimill so it is quite a bit smaller than yours. There are lots of conversions on the web but not a lot of info on stepper sizes. From what I've seen, if you plan on using ball screws you likely will need larger steppers or use a belt drive reduction. Currently I'm planning on using the existing lead screws so I hope I can drive them directly.
Good luck with your build.

Ya I found it really hard to find any infor regarding size of the stepper to the size of the machine. Thank you for providing some insight, good luck with your build also.

Look up hossmachine. There is alot of info on the conversion. Mine was nowhere near 150$ though.

That's the one I use. But I think the 380oz is the minimum recommendation for it.
Anything else I can help with let me know
