  1. Hello everyone.
    This is Nick from Greece.
    I am looking forward to build my own cnc and to avoid the most mistakes that will cost me money, time and mental brakdown!
    Althought I am a member at other cnc forums,I choose to post here my attempt for some reasons that I will prefer not to analyse right now.
    Sooo, I am planing to build a cnc with the dimensions I wrote above.Steel frame and bench, I am planing to combine welds and screws for the bench since my workshop is small and I will have to build the machine outside the workshop and disassembly it and reassembly it again in the working area, this will also be a one man build , so this way it will be a little bit better for me to relocate it.
    The cnc will be used most for wood working, guitar building, etc and I will be pleased if it will be rigid and accurate enough so I can cut aluminum parts.

    Caution My cad abilities are awful,lol, prepare your eyes!!!
    CAd program I use is Rhino 4 and Vectric Aspire 4 for cam.

    Thanks everyone for taking the time to read and special thanks to everyone that will participate to that attempt!!!

  2. Yesterday at work I felt very lucky, since I thought I found my machin ,almost ready ,build for me!!!
    But unfortunattely someone place an engine on and I lost my chance.

    Hi Nick,

    I'm still learning, but some of the best bed frame designs I've seen have a bed which attaches to the legs with screws, so you can change the height of the bed, or swap it out for a different one in the future. The other thing I thought was quite sensible would be room at the front and sides for sliding large pieces in underneath to work on their edges - looks like you've hit the nail on head already for that one though!

    Hope that helps!

  5. Any thoughts about the design and the dimensions of the steel tube I use?

    I think 3mm is a bit thin for tapping into

    Hi Andy.
    Somehow I miss your post earlier.
    Thanks for the comments, I read other's guys threads here and I am stealing ideas, I hope this is not inappropriate. :-).
    Something I forgot to mention is that at the one end of the bench ,that is at a lower lever is for the rotating axis.

    Hi, May I ask what rails/tracks/guides you are using and what is the method of attachment? What do you want to cut?
    The span of the section is where you need to pay attention. Mass/stiffness can be your friend.
    Welding can be you enemy with shrinkage and distortion. The 50 x50 x3 might be used for bracing , but the main rail support might be stiffer with 75 X 50 X 5.0 RHS.
    Tool load and weight of the material you are cutting will also dictate frame material properties. Sorry not many answers and a lot of questions.

  10. Hi Paul, thanks for your participation to this thread.
    Rails I am planing to use HIWI linear square rails, attached with screws .
    I am planning to cut wood mainly and I will be glad if the machine can cut aluminum also,I know that I can not have a cnc that can do both works well, so the main purpose is to build a cnc foe woodworking-guitar building.
    Thanks for the input about the main rails, i will use it at my upgrate workbench design.
