When you fire up your CNC machine, let it align to machine-zero with your limit switches. I place them in the top and bottom corners on the left side and in the center on the right side to complement the placement of the woodworking screws. ![]() In the design, the holes need to be positioned symmetrically above and below the centerline of the workpiece. ![]() In your project design, create a template to drill three holes at the left and right edges of your piece. On the right side of the workpiece, I drilled the screw holes near the top and bottom corners. For my layout, I placed the screws to be approximately at the middle of the left side of the piece. The dowel holes will take care of the alignment, so you can be a bit sloppy where you drill the screw holes. You don't need to have the screw hole locations perfectly placed. Drilling and countersinking the screw holes is critical to prevent you from you straining or even splitting your workpiece. Place your workpiece on top of the sacrificial board, drill and countersink screw holes, and then attach it using woodworking screws. ![]() This piece needs to be firmly attached to your CNC base during the entire carve of the project. The best way that I have found to do this is to create a sacrificial alignment board to place under the piece you are carving. Creating three-dimensional two-side projects might seem a bit daunting at first, but it turns out that your machine can do this easily as long as you use a few tricks for aligning your wood and your design when you carve the backside. The majority of CNC projects are one-sided signs or cutouts of projects from larger sheets of wood. I wanted to spend a few paragraphs on the principles of the project before we get into the harder details. Ok - roll for initiative, and then let's get started.Ī key element in the design of this project was creating two-sided CNC carvings.
