Arduino CNC engraver
It's been a while from my last video. Meanwhile I have upgraded my CNC plotter little bit :) First - I added limit switches. They are buttons from old printer, attached on piece of plastic. Now is it possible run homing cycle command. Works great. Next - I added small DC motor, connected thru MOSFET, so is it possible control on/off spindle directly, using GRBL and G codes. And finally - I have mounted small chuck (from Ebay) to DC motor, so it is possible use small engraving tool or something else. Enjoy the video :)
