Mount a rc-brushless outrunner using stepper damper for reducing vibration and noise.
Small 250 rc heli motor with 2,3 mm shaft for easy fitting cheap chuck. Brushless controller connected to servo pin on printer board. You have to activate servo in marlin so you can control motor from gcode. Holes for CR-10 and CTC i3 pro B.
Nice setup for living-room milling, works very good for me ;-)

For gcode creation I use blendercam which works also very good for me. Also for 2D engraving you can use my program qdiiibp.de or inkscape laser plugins pasting z up and down gcode for laser on and off commands.

Included also a versin for direct motor mount without stepper damper and iges files for easy editing.
