SainSmart CNC 3018 ProVER Parametric Spoilboard (and others) -- Source Included

<p>This is a CNC spoilboard I coded after looking at a few designs around the web. I wrote it for my SainSmart CNC 3018 ProVER with the Y extension (3040). If you have this machine, this may work for you, but check that the measurements are not out of bounds for your machine.</p> <p>Examine the source code. Most values are variables that can be modified to suit your setup.</p> <p>I used MDF from Home Depot, a big box hardware chain in the USA. I got the boards cut pretty close to size in the store, taped two together with blue painter's tape, clamped them down and let the machine do the work.</p> <h3>Creating the GCode</h3> <p>To generate the tool path, I used Fusion 360. It took me a while but it worked out. I found the best way was to go to Design and Insert Mesh, then I converted it to a solid and did a 3D Pocket operation.</p> <h3>Cutting the MDF Board</h3> <p>I used a 3.175 mm bit, and I think I did about 0.2 mm passes as I was afraid to go too deep with the cuts. This was my first CNC design.</p> <p>I used CNCjs to cut the spoilboard.</p> <h3>Optional - Plastic Screws</h3> <p>I was, and still am, scared I will drive the cutting bit into a metal screw or bolt. I made the mounting bolts out of PETG. It is not perfect -- at this point the MDF slips a little bit if the board is pushed with a little force with 3 bolts attached. I may try hair spray on the bottom of the spoilboard. I may also try to use more bolts. :)</p> <p>Use regular bolts if you want to, I'm not stopping you. They will certainly hold better.</p> Category: Tools
