Estlcam, it’s well worth the money. Some of the stl files are to tall, I use Slic3r to rescale or slice them in the Z axis. All of the designs came from, cults3d.com/en, 3axis.co, Thingiverse, all free designs.
For the flag I made stencils from fascia aluminum and cut them on the MPCNC. I had to file/sand the edges a little to clean them up and fit flush on the wood. I have a planer and I run the 1x12’s through once on each side just to clean them up. Paint the Red and Blue, let those dry, then the white. Carve the flag and Pledge. Burn the edges, clear coat. I have the outer text in a different file so I can change it. I have alignment lines drawn on my waste board.
