DIY Mini CNC Engraving Machine | Arduino based CNC Router machine

$2/5pcs 2Layer & $5/5pcs 4Layer PCBs: Hello friends in this video I have made a mini CNC engraving/milling machine. this machine based on arduino and GRBL firmware. 12mm plywood is used to make the frame of this machine and nema17 stepper motor is used for all three axis. 8mm smooth rod & T8 lead screw is used for all axis 500W spindle is used which is quite enough for this job. I have tested it on wood, acrylic, and PCB it works well not tested on alu. but shallow cuts with high quality of endmill done the job I think. All the dimension details of machine and components list available on my website please visit below link.
