New to CNC and 3D software but I'm jumping in head first and building myself a 4'x8' machine on a tight budget. As I get more experienced the plan is to upgrade and modify the build with stronger components for the drive. I chose using belt and idler pulleys for the X and Y and ACME screw for the Z. Eventually going for rack n pinion for the X and Y or possibly a screw for the Y, dunno yet. From what I've read, a 4x8 table is a big build and has lots of obstacles in terms of accuracy. The largest material I'm currently planning on cutting is 4'x8'x1" MDF and 4'x8'x3/8" polycarbonate. Once I get the hang of things (on the software side) I would like to do more intricate pieces. Being so new to CNC, my biggest hurdle is the CAD software in a 3D space. Any suggestions for something relatively easy to use and make basic pieces would be very welcomed. I have downloaded trials of MACH3 and 4, QCAD CAM, Design Spark, FreeCAD, HeeksCNC and SprutCAM. I have yet to really get used to them and have seen "drag n drop" style software which I would appreciate anyone that has had an easy time with certain ones. Cant wait till my parts get here!
