In an effort to better understand how CNC Routers work, I decided to build onefrom scratch. Having little confidence that I could pull it off, I came up witha plan to break it up into smaller wins.
The first step was to build a CNC mostly out of reclaimed electronics. I learnedthat the motors in many cd rom drives are stepper motors, so I took apart someold computers I had access to. For this build, I only needed to purchase 3stepper motor drivers and an Arduino.
With this success, I had the confidence to buy some NEMA 17 motors and scale thebuild up. This build worked mostly fine, but the motors would occasionally stickand I got the feeling my naive design was to blame. About that time, I hadpurchased a 3D Printer and decided to put it to work for me. A little researchrevealed the MaduixaCNC.
