Box joints on Shapeoko 3

[TOOLZ (Brian Ulrick)]

Hi All,
I have the vertical table set up on my #3. Would like to try cutting small, 1/8" or smaller box joints.
Anyone done this ? JointCam software or other methods ?

Thanks in advance !
Brian

I wrote a bit about this at:

CNC Box (Finger) Joint Box

Working up a tutorial on this for the wiki: but is now at: First step is to create the box itself: This is done in OpenSCAD using the parameters: length = 6; width = 3; height = 4; thickness = 0.375; bottomlidthickness=0.125; pins=13; partspacing=2; Next resolve the pin/joint size and spacing: [cnc_box_fingerjoint] Next step is to work out how to get from the above parameters to a file which may be easily cut using Carbide Create — probably using METAPOST.

and expanded on it at:

Box (Finger) Joints

That said, I think a partial blind technique which allows cutting things flat on the machine is preferable — single setup/fewer operations and w/ the technique shown at:

https://community.carbide3d.com/t/a-box-in-2-or-3-or-4-maybe-5-toolpaths-and-a-few-operations/47039/10

should allow one to cut one set of parts (say the sides), then to cut the other parts (the ends) and test the fit — if things don’t fit, then adjust the file and recut until things to fit.
