I have done this manually with a router and a 7/8” v bit with the bearings. But I have an x carve (dusting it off)
What would be the best (without being an expert in fusion 360, without spending over $100 on a bit, or $$$ on software) way to do this on the x carve? I do have easel pro available to me.
- don’t use x carve (perform rough cut on table saw and follow up with manual router step)
- can this be done with the small 90 degree v bit inventables sells? some software game plan?
- purchase large 90 degree v bit with the chamfer being 1.125” long? if so, suggestions of where to purchase? Easel could then be used, right?
thanks

If you have a larger piece of wood, then you make the carve very easily, even without Easel Pro. Just make an oval the size you want, and use a 45º V-bit that’s long enough to cut all the way through. You’ll probably want to tweak the depth-per-pass value so it’s not removing too much wood each pass. For v-carving, I also like to set the depth-per-pass so the final pass is removing a tiny amount. For example, it you have a 3/4” piece of wood, I might set the depth-per-pass to something like .124” or .235”, so it nibbles away just short of 1/8” or 1/4” each pass, and the final pass is just a sliver. It seems to leave a much nicer finish.
Assuming you are cutting all the way around with the bevel, then just set your cut to be “on the shape” instead of inside or outside. This should leave you with a final size equal to your original design (± some error for depth).
If you are using Easel Pro, then it’s a little easier as it shows you the V-carve result.
I made a little example here to get you started: Easel - Oval Test
Another thing you can do, if you want the chamfer to only be part-way through, is to use 2 workpieces. One carves the v-bit down to, for example, 1/2”, carved on-the-line. Then, duplicate that workpiece and switch to a regular straight bit, carving all the way through outside the oval. It’s a little bit of setup, but it works pretty well.
All that being said, unless I was dealing with something large, a complex shape, or needing to cut all the way through, I’d probably cut the piece out flat, then use my router table to add the chamfer. The CNC is great for some things, but often I find it’s just easier to manually route edges later than to switch bits and hope I don’t screw something up.

please help im looking for the z axis upgrade for the xcarve i cant fined it anywhere. its sold out on inventables and cant be found on ebay or anywhere online
Thank you for the suggestion. I have not yet found a 1/8” shank 90 degree v bit that is large enough to cut all the way through 3/4 mdf (true 3/4) or plywood. I have previously performed the bevel on my router table manually.
Would anyone have any guidance for using the inventables 90 degree v bit in the 2nd stage detail 3d carve of easel pro?
I see where I can setup a bit but I’m not sure of how to setup the bit. Someone had said the inventables vbit has a flat top.
So below is a pyramid (make in tinkercad).
The board is 3/4 inch. I might not have setup the file properly but I can get to that.
Pyramid.stl (1.6 KB)
Any suggestions on how to set this up to carve?
2 stage easel 3d carve:
-3d carve
-rough 1/8” end mill
-detail: 90 degree inventables: what settings?
It would be great if I could do this with the software moving the v bit.
thanks,

All of the V-bits I have go basically to a point. I think the reality of metal means you can’t get a perfect point, but it’s like, 0.1mm at the tip or something similarly tiny.
If you just want to cut a pyramid shape like that—and your v-bit is long enough—it should be as simple as setting up a rectangle with the dimensions of the top of the pyramid, and tell it to cut with a 90º detail bit. You won’t even need a roughing pass.
The 3D preview in Easel should show you the final design.
If it’s as small as it looks, I recommend forgoing tabs for holding it down, and use the blue-tape-and-superglue trick. Just make sure there’s glue under where you are actually cutting! 
My challenge is I cannot buy a 90 degree 1/8" collet v-bit that is long enough to cut through 3/4". It seems that my easel pro defaults to the 1/8" ball nose for finishing pass. Is the following possible?
-add the small inventables 90 degree v bit as a pro finishing bit, what bit settings to use?
-set up the 3d carve by importing the pyramid stl
-rough pass 1/8 bit straight
-finishing pass 90 degree v bit
-what are the settings I should use to add this bit in easel pro for finishing pass
-what cut settings should be used for this finishing pass?
This would allow me to use readily available v bits and also place a 45 bevel on > 3/4" material.
Apologies for asking the same question more than once in 2 different threads
thank you

I understand now, sorry. I don’t think you can finish with the V-carve bit in 3D mode, but I’ve never tried. Maybe someone else can help here.
