Homemade PCB milling machine

For those asking for the plans, BOM, etc, I merged all files in a 7-Zip file so you can download it.

It's included:
 -  the complete 3D model (in Solidworks format, main file is CNC.SLDASM)
 -  the 2D drawings used to machine the parts (if it doesn't have a 2D drawing, it's a laser cut part, so there's only the 2D DXF file used by the laser mahines)
 - some pictures from the assembly
 - a powerpoint presentation about the project

Note that all material is in portuguese. It shouldn't be a big deal, since you can check all data and dimensions on the 3d model.

It was a graduation project, so if you have interest send a message and I'll send you the paper explaining the design choices, calculations, etc. But it's in portuguese as well.

A few notes that I remenber:

 - A couple of hole were modeled with the wrong diameter, but I don't remember which ones anymore.      
 - I wouldn't use countersink bolts if I had to rebuild this machine. It gave me a lot of trouble when aligning the linear slides.

If you have any further questions feel free to ask.
