Auto Z and Corner Finding Touchplate for CNC - Remix

thingiverse

I wanted to give this a smaller profile than the original thing. I removed two walls from the square top to make it easier to slip under the router bit. I think it is also easier to attach the aluminum tape to the model without those extra walls. Remixed in OpenSCAD. As you can see, this is merely a bunch of extruded rectangles and squares. I made it a bit thinner as well. Source is included. I use CNCjs and based this corner finder code on one of its stock macros. Adjustment will involve some trial and error -- don't expect to get the proper values right the first time around. The GCode is attached. I do not expect it to directly port to another application, but you should get the general idea of what is involved.
