Hello Vectric Community
I have recently bought a Chinese CNC with a 4th axis and have been trying to machine an STL file of a cabriole leg. My problem is I have no idea what to set as the model thickness since it not even on all sides. I have tried to watch videos on you tube but this step is always missing. How do i go about it?

Re: Cabriole leg machining
Pay attention when you import the stl file.
The import screen will show you the length and diameter of the model and allow you to scale the model.

Hello TReischl
Thanks for your response. On importing the stl file the values indicated were length 391.427mm which i set at 400mm while the diameter indicated was 99.221mm which i used 100mm for the material. The others were Gap outside model 0.043 and the model thickness set itself at 49.608 while the model plane was 0.349mm. I used a 12mm ball nose for roughing but I stopped the roughing process when i realized it was almost roughing to the center. My guess was because of the Model thickness but I have no clue what to set it.

Re: Cabriole leg machining
Not sure what you are making?
Some models do not have material left around the centerline, those are a problem.
One thing you can do is model up a small cylinder, say 6mm in diameter and see if that surface shows through on your model. That will tell you a lot about where your model is in relation to the centerline of the rotary.
Other than that, you might want to post a screen capture of what your model looks like. BTW, what is your toolpath preview showing you?

Hi TReischl
This is the stl file I've been working on.

Re: Cabriole leg machining
Oh, I know that leg well. It takes some fiddling to get the model adjusted so the centerline is covered.
Under Help/Video Tutorial Browser look for the video Rotary Import & Unwrap Full 3D starting at the 4 minute mark.

Hi Rcnewcomb,
I have now watched this tutorial and its very similar to what I need to do. I will practically do it and post the results. Many thanks.
