A couple years ago I bought very similar chuck and tail-stock pieces from China. I've started to put them on my CNC a few times. Your video has given me some new ideas and maybe the encouragement to finish it. Thanks - Good video.
Nice addition. Looks like a great unit. I think the biggest step forward for hobby rotary cnc work was when vcarve added the rotary option for design work. So much easier to do a project after v9.5.
Dave, I never thought of doing the rotary axis on top of the table. For some reason I though you had to have a cut out like everyone else which I didn't do when I built mine. Now that it's possible I might buy me one too. Thanks.
Thanks for posting, this is an upgrade that I am interested in getting in the future. I am actually planning to buy your plans to build a Gatton CNC shortly. Is there anything that I should do differently when building the CNC to future proof for this upgrade? Where can I find additional details on how to wire/ setup the rotary axis to the standard CNC?
When using the Vectric software you can select to Z zero on the top of the material or at the centerline (axis) of the material. I like to use the centerline so to do that I found Z zero without any material in the way by lining the bit up with the point on the live center. Then I moved the Z axis up to the top of the aluminum block of the live center. Now I know the distance from the top of that block to the centerline of the axis so I can use the top of that block to Z zero and just add in the distance down to the centerline without having to remove the material that's already chucked up. Thanks for watching Ryan.
is it possible to run it faster? i'd love a rotary axis as it's pretty involved to convert a CNC lathe, but i cringe a bit when i see how slow a 4th axis is compared to a lathe!
@@DaveGatton oh i know that carving isn't possible on a lathe - maybe i should reframe. i'd like to engrave some things with a rotary but i'd also like to use it to shapesimple plastic and wood pieces. if i had a 1/4" bit in my router i could hog off a lot more material than i could with a tiny carving bit, similarly i could take a lot more material off if i was running the 4th axis more quickly. so i'm wondering if it's possible to run it a lot faster.
@guitarchitectural yes. You can go pretty fast with a roughing pass but to get a smooth finishing pass the step over is so small that it will take a while. There's no sense in getting it done faster just so you can spend time sanding.
@@DaveGatton Their rotary axis actually comes from JTech - so anybody can buy it and you do not need to have an Axiom CNC. I looked over the specs sheet side by side , comparing the 2 products and I'm not an expert but their doesn't seem to be any difference. Which leaves quality of materials used in construction and engineering to justify a 500 dollar price difference.

That little bit was actually very helpful. Thank you.

Thanks for watching John. I hope you something useful from my video.
Enjoyed the build thanks for sharing you have a blessed day
Thanks, you too!
Awesome find Dave. Thanks for sharing.
Thanks for watching Dave!

Thanks for watching Rob. Yes the newer versions of V-Carve make rotary axis work pretty easy. Even I can do it. :-)
Nice upgrade.
Thanks for watching Peter. I think I'm going to really like this new one.
Really nice Dave thank you for sharing
Glad you enjoyed it
You could also add a vertical fence to help keep the tailstock in-line. I did that with mine and i'm super happy with it :D
Thanks for watching Zach. I think I'm just going to go back and do it like my other one. Simple is better.

Thanks for watching Larry. Just between you and me I think the table cutouts are totally unnecessary. ;-)
Awesome Dave. Thanks for sharing!
You bet! Thanks for watching Carlo.
Nice Job Dave! Stay Healthy!
Hey Dave. I clicked on the link, but no seller in Canada. That looks like a nice solid unit. Thanks for sharing..
Thanks for watching Grant.

VERRY USEFULL
The bit you are using, looks like a 1/2" shank. What is the length?
Dave - have you already done the math on the steps per? Looks like a fine step motor, but hard to tell.
How do you zero with the rotary?
When using the Vectric software you can select to Z zero on the top of the material or at the centerline (axis) of the material. I like to use the centerline so to do that I found Z zero without any material in the way by lining the bit up with the point on the live center.

Thanks for watching Ryan.
Dave, did you have to make any modifications to this or was the setup good from the manufacture?

You're comparing apples 🍎 to oranges 🍊. Try doing a 3D carve on a lathe.

What driver are you using with the stepper? What size is the stepper?
DM542T from stepperonline.
Hi Dave - how does this rotary axis unit from China compare in quality and performance to the unit that Axiom provides?
Thanks for watching John. As for the comparison, I don't have anything by Axiom so I have no idea of their quality.

Ok
this is quite cheap compared to the over $2000 that AVID cnc asking for their rotary axis. It contains extrusions though
