    I opened his file in Rhino and resaved it as autocad12. Maybe this will work. Uh, dxf, that is...

    That was the ticket! Thanks for the help!

    Ok, I've already admitted I'm new I've looked this file over a bit and from what I can tell it's a nice design. I am confident I can build something similar but need some more basic info. Could I get a kick in the right direction?

    I guess I need to learn everything else. I know, you've all probably heard that a thousand times. I'm a quick study. Any good resources? I'd like to find a drive system and the electronics etc... that all work together to make it simple. I don't want to make this any harder than it is. Oh, and please forgive my lack of correct terminology. I'm still learning the cool new words

    Duhhhhh Isfoils I never thought of that! I also didn't know you were a Rhino user! You're from somewhere up in the northwest aren't you.

    How long did it take you to get proficent with Rhino? I am self teaching and I want to let you know I don't have a very good student! Can you take a rendered image and turn it solid in Rhino. I know it is probably in the tuts but I have been so busy trying to make a living I can't spend as much time as I really need to on the program.

    Darren,

    Check out ebay. There are lots of CNC Controllers being offered there. If you have had experience with electronics then you might try your hand at making one. I didn't. I purchased a 3 axis controller that had the power supplies on the board with the basic hook up for the printer cable and drivers mounted. The guy offered 3 stepper motors with purchase of the board @ 30.00 each and I got those as well. Worked out. The system worked great as the guy knew what he was doing. I was into it at 350.00 with shipping when it was all said and done. There are cheaper ways to do this and you should check out other threads in the Zone. I also purchase Mach1. Its the software that lets your computer talk to your machine. 125, I think.

    Turmite,

    I am self taught with Rhino as well. Man, what a kick butt program! I have created solids using it. But, I am sure I am doing it the hard way. Be glad to share the misery if you have q's.
    Yep, I'm just south of the boarder and very near the water. (even get to sail once in a while)

    IsFoils,

    I'm pretty good with electronics, used to work in the industry a while ago as an electronic assembler so I have no problem as long as there are plans and schematics. I'll take a look around the forum and see if I can find something that looks intersting.

    Thanks again.

    Darren

    Doug if you will pm or email me you email address I will send you the 3dm file to look at. There is a fellow in Bellingham right now that is going to do it into Solidworks for the moldmaker that is making the mold. I want a good solid from Rhino to test 4 axis cams programs with to see which I am going to buy. Another option would be to post it here if I knew how. Talk me thru that if you want to.

    Probably the best performance for the price. And you can get everything you need from him. Also, great support. Email him any questions you might have, and he'll answer them promptly. For a little less money, you might want to look at http://www.hobbycnc.com
    but you'll have to assemble the boards yourself.

    Wow, the Xylotex looks like a great deal, hardly seems worth it to assemble my own for the price difference. That and the support is a big plus.

    Another nice looking package: http://www.hobbycnc.com/package.htm

    Would the 125oz motors be sufficient for what I want? Sorry, still researching.

    Ok, I've been doing a bit of reading, let me know if I'm thinking correctly. I'm trying to learn fast as usual.

    The design of the actual machine is just whatever works and is solid, many different implementations. The items that need to be "standardized" if that is the correct term would be the drive mechanism and it's mechanics. So, the threaded rod, step motors, and the drive board correct?

    Could someone recommend a good step motor for cutting 3/4" MDF, hard wood, and aluminum? I'm assuming a minimum torque would be required for a reasonable cutting speed. I suppose I should be considering that it would possibly take multiple passes to reduce the possibility of chatter etc...

    Thanks for all the help so far guys.

    Darren

    You probably won't find a better deal than the 3 116oz-in motors from Xylotex for $60. Although you might be able to get the same motors from Ebay for a little less. ( It's the same guy that Xylotex get's theirs from.) I got some 250oz-in motors on Ebay for about $65 each, but they don't turn up very often.

    On that machine I used 100 oz motors. With a xylotex board and thier 116 oz motors and 1/2-10 acme rod with a 24 volt power supply you will be able to cut your MDF and hardwood no problem. Rapid moves will be in the 20 to 40" per minute range as long as the machine is built straight.

    For software you can run Turbocnc (inexpensive) or Mach 1 (a little more).

    Don't worry about the software now. Just get the mechanical end done. Plenty of time to play with the saftware later...

    Eric

    P.S. I just looked at the plans again, sorry they are such a mess. I should clean them up.

    I wish it wouldn't crash.

    Thanks for the additional info, you are making this much easier. It looks like I'll be able to get what I want within my budget for my first CNC Router. I can see myself doing what you did later on down the road and build a bigger better faster router using the first one

    So, I order the xylotex board and motors, build the machine, then get the software and tie it all together right?

    Is there anything else I need. I noticed in your most recent project you have a break-out board etc... will I need to have some other interface?

    Thanks again for all the help from you and the others. I'm getting a real good feel for what I'll need.

    Darren
