I would think back to back would be the best option. However, I don't have a clue what the separation should be. Wonder if they need any separation at all????

Oh Boy, that was over 2 years ago. I believe I just picked them up on Ebay. As I recall, they are 17mm ID. Don't know what brand they were...

Another day, another step forward. Today I got the X-Axis rails installed.

Today I got the Y-Axis rail assembly installed. These attach to the extrusions with 1/4" carriage bolts, 2 on each end.

The Y-Axis stepper is just sitting in there, but this is the...

I milled one aluminum plate at a time without lube although in retrospect, lube probably would probably have helped. The flush trim bit was a 1/4" shank and if I do it again, I'll get a 1/2" shank...

I decided to go ahead with 3/8" aluminum tool plate for the sides. Here is a picture of the sides and extrustions cut to size...

I first made an MDF pattern for the sides. Then I rough...

Here is the template for the frame sides, dimensions shown.

I have an XHC ShuttlePro which I believe is a WHB03.

The only driver I've been able to find is version 3.3 (I believe). ...

This weekend I made the clamp assembly for attaching the router motor to the Z-Axis.

Got the X-Axis mostly finished today. Still hae to drill mounting holes in the end plates of both axes.

My stepper motors arrived today. I have quite a bit more stuff that I can work...

Thanks for the videos. I had thought long and hard about the scaled-down BBox. It's straight lines and assembled side panels use less material and make it easier to keep everything square. But, at...

I actually got most of my inspiration from Microcarve's MV2, then made some of my changes, including a modest increase in size. He's removed a lot of his pictures and descriptions from the his...

I am using a dovetail slide for my Z axis. I made this out of two pieces of 3/4" thick aluminum with the dovetail overlap being about 5/16". Overall dimensions are 7" x 2.5" for the bigger piece...

Ahh, I hate it when well-informed and knowledgeable folks cause me to second guess my decided course of action... :^). Wish I had not purchased the 12mm ballscrews. But, since I have more time than...

So, are the KERK lead screws the same thread form as an ACME thread? I see that KERK offers a lot of different pitches whereas ACME comes in a few standard pitches. Where does one buy the KERK lead...

Thanks, Chris, for your comments. I appreciate anyone who takes the time to share their knowledge and experience. I do have a small machine shop with an 11" Logan lathe and a 7" Harbor Freight mini...

After months of planning and designing, I've begun construction of a small, Desktop CNC router. It will be a fixed gantry for the X-Axis and a moving table for the Y-Axis. Work envelope will be...

For a long time I've been contemplating building a small CNC Router. I've never started one because I already have a CNC milling machine and didn't see the point. However, I ran across this little...

That's a good point, I hadn't considered that... Might be one more reason to use acme or even a standard thread on the Z-Axis screw. I don't anticipate doing a lot of 3D contour work, more just 2...

Most if not all Z-Axis assemblies I've seen use round rods or linear rails for the slide. Just wondered if anyone had considered using a dovetail slides on the Z-Axis?

No good reason for the Z-Axis ratio. The largest pulley that will fit the down feed shaft and still leave room for the belt is 36 teeth. I had originally planned to use 20 and 48 tooth pairs on...

George, I had to re-measure them since I didn't have it written down anywhere. The holes are 30mm apart in a square pattern that is 15 degrees off horizontal. I use flat socket head screws that are...

The timing pulleys on the Zed axis are 15 & 36. The belt is a 110 x 037XL. I didn't modify the Z-Axis feed in any way other than adding the motor & timing pulleys.

Thx...

Well, I thought I had attached the PDF, let me try it again...

You can calibrate all the Axes pretty much however your want. You simply tell it how many steps it needs to go a certain distance. ...

Attached is a PDF file of the drawings I made originally. I probably made some adjustments as I went along and didn't necessarily update the drawings. I know, for example, that I had to add about...

Thanks, Bubba. So, question for the group... I want to do some profile cutting in aluminum plate (I'm guessing it's 6061) using a 1/8" Kycera, 2 flute solid carbide bit. My milling spindle will...
