I’m using this Ball nose Vbit
But am having problems with corners not being sharp (Carbide thinks it’s a Vbit with no ball nose) so they turn out like this
I don’t know how to fix this and it appears on every corner. Is there a solution for this?

That is unlikely to be related to the ball end of the cutter. It’s more likely to be something in the file or machine setup.
If you can post your file here, we will take a look.
here’s part of the Gcode i’m using, it seens to be making holes where corners should be

There are no plunges that are disconnected from the rest of the shape, so I’d check that your Z zero matches what you programmed in the file.
I see from the support system that you’re running a machine you made yourself, so I’d also check that the axis movement is correct and nothing is jamming up.
If you preview this in a tool using a tool which matches what Carbide Create expects to be used you get:
So, the problem phrased a bit differently is:
I prepared G-code in Carbide Create for one tool, but when cutting, I loaded a tool with a different geometry.
no, I prepared carbide create with the same tool I loaded it with, a V bit of 10.3° and a 6mm diameter. I can’t tell carbide create that my Vbit has a ball nose becasue there’s nowhere to put in that information into.
So my question is still the same; workaround for CC v6 not supporting Ball nose V bits?
In theory, one could draw up the tool in profile, then determine what V angle would have the correct width of cut at a depth which corresponds to the majority of what you are cutting, but the facts of the matter are:
- Carbide Create v6 does not support this tool geometry
- Carbide Create v6 is not supported
- if you want support, you should be using the current stable version (v8 as of this writing) and if not using a Carbide 3D machine, buy a Pro license
V6 is the only free version where I can export Gcode for free and also do inlays with
There’s no way to create a mathematically correct V-carve using a ball tip. If the radius is small, the error will be small too (most Vee bits have a small flat at the tip.).
Or soon after develop one from new users!
