  1. Re: P4 ball screws that don't violate the bank or my behind...

    I got a quote from a vendor from AliExpress for my machine that seems pretty reasonable. I'm not sure what precision the screws are or if they come with the necessary nuts or not (I'm not ready to...

    Re: My third build, all steel this time!

    I read the post, but no one said why the profile rails were better than the round. Could you explain why you chose them over the round?

    Other than the length, is it more advantageous to go with a...
  3. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    So I received my order of metal late last week and got it home. I've been able to work on it some, but with a 16 month old, there's not a whole lot of time that I can spend on my machine, so the...
  4. Re: Why do you still have a vertical manual mill when you have a CNC router?

    I don't have a manual, but have used one and am in the process of building my CNC, but I would imagine that this is the primary reason. If I only need to skim a little off of a part, I would rather...
  5. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    Just an update. I Ordered all of my metal yesterday thru my works purchasing department. It should get here next Monday.

    I've been looking a lot more for linear rails and ran across this item:...
  6. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I wasn't able to find anything on youtube or google.


    What do you mean by ribbing it?


    If I'm understanding this, drop my outside verticals and place them under the top horizontal, like I...
  7. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I was more so worried about the .125" wall for my tubing. Whether or not it would be thick enough. I don't want to order the 60+ ft of steel to find out that the wall thickness is too thin. What do...
  8. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I finally got my modeling done to where I think the frame is finished.

    Attached are a couple pics. I decided to go with the 3x3x.25 box tube for the gantry and have the 4x8x.25 aluminum tube to go...
  9. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I've seen that 5 axis design a couple times. I'm not totally against making a 5 axis down the road, but I figured it would be a good idea to follow the wisdom of the others on this forum and start...
  10. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I got a little bit farther with my modeling. I haven't had much time to work on it lately.

    I updated the linear bearings to accurately reflect what the purchased item should be. I also added angle...
  11. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    So I found a design for a 3 axis machine that I like. The build post is here: BUILD LOG: 1.7*0.74*0.4m Mill / Router building... - Page 12

    I threw together a quick model. It is still very rough,...
  12. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I've looked at some more 3 axis designs and I've decided that I will try a go with taller rails. I'll post back when I have something drawn up.

    One thing that I noticed on pretty much all of the...
  13. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    Ok, well it didn't take you guys long to convince me to get rid of the 5 axis idea. I'll try for 4 axis then with the standard 3 axis and the 4th rotary.

    That being said, should I go with the same...
  14. Re: Attempt at 5 Axis. Constructive criticism is welcome.

    I do currently have the X axis riding on top of angle. Do you by chance have an online source for the some line profile bearings? What do you consider cheap? $100 for 1', or $100 for 5'?


    Could...
  15. Attempt at 5 Axis. Constructive criticism is welcome.

    Hi all,
    I am going to attempt to make a 5 axis router table. I have the bulk of the design done and am just missing a few of the finer details and feel that I'm close to the point where I can order...
  16. Re: Combine multiple drivers - Is it possible?

    I am still very much in the design phase of designing my first machine and I haven't really looked too much into motors or any electrical components yet.

    I am going to design for 3 axis, but am...
  17. Combine multiple drivers - Is it possible?

    Hi all,

    If I have a 3 axis CNC with a 3 axis driver, and down the road, I want to add additional drives (attempt to convert it to a 5 axis, or just have a 4th axis rotation), could I purchase...

    Re: Free DXF or IGS clipart

    You might try looking here Animals - Dogs - German shepherd or here Dogs - Dogs - German shepherd.

    It looks like you might have to register to download the files tho.

    Re: Might seem silly but I need a lock nut!

    Could you go with a smaller width?
    McMaster-Carr has this one in a pack of 5 for $5.11 (McMaster-Carr)
    Or this one in a pack of 1 for $2.58 (McMaster-Carr)

    They are not nylocks, but they are...

    Re: A Hapless EE Attempts a CNC Build

    I've read that some people have payed that much. If you are around a Menards, you can get 3/4" x 4' x 8' for $70.00...

    Re: A Hapless EE Attempts a CNC Build

    You might try looking at Baltic Birch. Its engineered plywood that is stiff with little flex and no internal voids. You can get it in multiple thicknesses as well. Its a little more costly than MDF,...

    Sticky: Re: Welcome thread-tell us about you.

    Hi all,
    I'm new to CnC -ish. I design custom components at work that are then made in a machine shop, but never actually run one. I figured it would be fun to make and run my own cnc at home and...
  23. Re: Calculations to find stepper motor for 5th axis. What motor?

    So to get the torque, it would be my forces, 29.98N + 10N, then multiplied by the pulley diameter (~.054m) instead of the diameter of the spindle (.108m)? That would give me a torque of ~2.15 Nm....
  24. Calculations to find stepper motor for 5th axis. What motor?

    Hi all,

    I am going to attempt to design and build a 5 axis CNC. I have the machine rough designed and am now working on modeling the fine details. I am working on trying to figure out the A/B axis...
