I noticed this link to an ebay auction:

4 PCS NEMA 23 STEPPER MOTOR 277IN-OZ SHIP FROM USA G540 | eBay

I want to build a small(ish) CNC machine. By small I mean 24" x 36" at the largest. ...

I see the EZ Circuit Board kit at HobbyCNC.com and it looks like a good deal. The listing says, "This system operates @34VDC giving much higher performance over 24VDC 6V 2A rated stepper systems." ...

I never said $1,250 was ALL I got for the car. This is what I was going to spend on the router. $5,000 is way too high for a "good" router. Tons of people agree that you can build an all-metal...

As a follow up to my own post....I decided to go ahead and get this:

That is the link. ...

Not that it matters too much, but i did say $1,250, not 1,200.

How much should I plan on spending on motors alone? Should I go with threaded rod? roller chain?

My main concern is the motors...

The title was just to get your attention. This is actually a very simple, two-step process.

1) Sell the 1965 Mustang Convertible

2) Get advice from CNCZone.com on how to spend that money to...

You don't know if you learn anything until you apply what you think you know ;-)

So, here is another auction I found. Different seller too.
...

PEU, thanks for the reply.

I think your post about being underpowered was a bit misleading. While it is true, it seems that the industry is not ready to power these motors to their full...

Holy Cow! So how much does a suitable power supply cost for these things?

Also, 15 mh is listed as Phase Inductance (as listed in the motor specs) is the same thing as Motor Impedance?

Please explain how you come up with your numbers. I've never heard of anyone putting more than 36V to a set of motors before.

Are you saying Phase Inductance is the same as Motor Impedance?
...

I found this on ebay. Seller has a rating of 4...so I guess this seller is new. Is this a good deal?
...

Is there a thread on here that lists reputable and fair suppliers for building a CNC machine? Suppliers for threaded rods / screws, stepper motors, controllers, bearings, etc? If this exists, it...

ilya,

If you're building audio gear, are you cutting wood as in the speaker box? Are you milling metal? If you're cutting wood, I think the 0.02 or so would be sufficient. People all over build...

ilya,

How many MDF machines have you ruined? You seem to be very knowledgable about MDF so it seems like you are speaking from actual experience rather than just the qualities of MDF in general. ...

As someone that found this thread because he's looking at building/buying a CNC router, I find it very interesting, especially the different perspectives.

There are people that highlight Patrick's...

FYI for others that find this thread...

What about aluminum? This is a non-ferrous metal right? I might be...

In my research, I've seen the majority (actually all, but i'm leaving room for hope) of places say that you can engrave and work with non-ferrous metals. I'm learning so correct me if I'm wrong in...

Looking forward to an update on the progress and pictures...

sorry about the slow response. I started a new job on Monday and it's been taking a lot more of my time than I thought it would in the first week. I did receive one quote in the other thread...

Wesley,

Thanks for the message. I called and talked to your son. He said it would be 3 - 4 days worth of work to cut out the MDF pieces. That just doesn't make it worth it for me. Looks like...

I'm looking for a person that is willing to let me pay them to cut out MDF parts from the BuildYourCNC.com website if I order the files and plans. I'm in the OKC area. If there is someone here...

I'm looking to hire someone to help me cut out parts for a CNC machine. The files are ones sold by BuildYourCNC.com. I would like to bring the g-code files and materials and pay to have someone cut...

Ok. $1,275 for everything but the steppers, controller, power supply doesn't seem as good of a deal to me. I'm sure it might be great for it all being metal, but I'm not that concerned with a...

It looks like the Hybrid 4' x 4' and the Stepper, Controller and Power Supply from MikeBeck.org would be a good combination. That'd be about $1,000 counting shipping costs as well, $1,100 if you buy...

What is the size of the 2006? I went to the website but don't recall seeing exact dimensions of the cutting area.


EDIT:

Ok, just saw it's 24" x 48".

I do like the 4' x 4' design better. ...

I think a 2' x 3' would be large enough for me to begin with. I'm planning on using it for my own enjoyment. Maybe do a few projects for friends. There are all kinds of little antique shops around...

What will you be using for steppers / controller / power supply? If you don't mind saying, how much did you spend on the steppers? If you've not bought them yet, what do you plan on spending?

Am I correct in assuming that those Joe's CNC kits do NOT come with Steppers? If so, I think they're WAY too cheap. What size of steppers should be used with those? 390 oz in?

Thanks for the insight. I understood it the way you explain it. Energy has to go somewhere, and if you're sending more than necessary, it usually isn't good. That heat can build up over time and...
