You use onshape right? I’ve been using this feature script cnc joint featurescript and it’s awesome. I’ve build 5 or six projects with it including: First retrieval tool caddy and great onshape feature for cnc joints
It’s faster for me to use this than to make dados in onshape. You just create your box, cabinet, table, whatever with all the jointing piece overlapping then select tenon and mortise pieces. You can do basic finger joints, tabs, hammer tenons, and hiden versions of all of the above.
I always have a variable for cnc tolerance which I pass to each instance of the feature script so I can do a test part and tweak that until I get the fit I want and then cut everything.
