Another big update, this time we are going to be looking at cncing all the internal shroud components.So, a CNC in simple terms works by taking a drawing and converting it to co-ordinates so that the router can follow the lines drawn. You can set the depth, speed and tool to be used to allow the machine to cut cleanly. Some projects suffer from what’s called tear out, where chunks of the material chip off during the cut process. After taking some measurements from the case, I then drew what I needed in my CNC software. The picture below shows from top left going clockwise, 2x thin strips to cover the existing cable management cutouts, 24 and 8 pin cable combs, the main front plate for 120mm fan mounting, with holes for the radiator tubing, fans and screw holes. The large piece at the bottom is the basement shroud with 8 pin GPU connect pass through, to cover the existing be quiet! modular sections. Finally, we have the left-hand side of the vertical shroud including 24 pin cable pass-through holes. So now we have the drawing of the parts we need to cut, we can export the “co-ordinates” to a file that the CNC can use. Now we need some material, I’m using 3mm plastic for this so that’s something else we need to tell the machine so it knows how deep to cut. We peel off the protective coating and fix the material to our waste board of the CNC. Next, we have the actual cut process, this happens quite quickly so I took photos as and when I could. Next, we have to bevel the edges for the vertical shroud, rather than do this in the CNC software I use a DIY router table on my CNC for small jobs like this. Also see I only use 2 tools to cut the whole shroud, a 3.2mm straight cutter and a 90 degree V bit.
