$500 DIY CNC Mill

thingiverse

This is my fully custom, under $500 CNC router/mill. This tool has successfully cut through birch, plywood, poly carbonate, acrylic, and aluminum with ease. The finished cutting size of the machine measures 34" x 33" x 4" for X, Y, and Z axes respectively. All parts can be found in the full assembly file in the CAD, so if you want to build your own, there it is! To give a more detailed description, I chose belt/track powered for the X and Y axes, with two motors driving the Y axis. NEMA 23 stepper motors and TB6600 - T4 drivers were used for power. Three-foot long aluminum 2x3x1/8" box tube was selected as the structural component material, while poly carbonate plates and plastics were utilized throughout. The router was an avid power 1.25 HP router, and all necessary hardware components, including standoffs, lead screws, lead screw nuts, and belt tensioners, were sourced from servocity.com and gobilda.com. Timing belts were obtained from mcmastercarr.com, while 3D printed parts (pulleys and stabilizers) were created at home using PLA material. The mach 3 software was used to control the CNC.
