About this 3D model

Converted my MF70 into a CNC machine Movie on Youtube of the working installation http://youtu.be/Ym2F4K-aEmI?list=UUE8NkpMoQ6UYm47mVXeUtgw Used a slightly modified Marlin Arduino with 3 NEMA 17 Stepper motors and DM422C stepper drivers. Control of the drill is done by the 'fan' output of the arduino that control a 5V relays. For the control of the Arduino I used a Raspberry Pi with Octoprint.
