I’m new here and haven’t cut anything except some test pieces with my MPCNC, but I’m coming up on a project that could really benefit from it - the Pinewood Derby.
My 9 year old son and I are entering separate cars in the derby this year and we’ve developed some pretty intricate designs thinking we would have the benefit of the MPCNC to cut them out. If I was cutting them from a sheet of plywood, that would be pretty straight forward, but we are required to use the pine block included in the kit there are portions of the 7 x 1.75 x 1.25 inch block’s perimeter that are untouched in the final design, so my zero point needs to be dead on.
My plan right now is to mill out a 7 x 1.75 inch pocket in a 2x4 and attach the pinewood derby block to that with some double-sided tape. That at least gets me the 2d shape. I haven’t tried doing any 2.5d work with my MPCNC yet, so please share any tips.
Right now the cars are designed in SolidWorks. I can resave them as STLs, DXFs, or probably just about any other file type.
