Draw on bottles using a CNC plotter made from old printer rollers and other scraps

from arduino.cc

To label used bottles that would otherwise go to waste, “tuenhidiy” created a CNC plotter that itself consists mostly of scraps!

The machine’s X and Z axes are formed out of a pair of old CD/DVD players, but instead of a traditional Y axis, it actuates two printer rollers to turn a bottle forwards or backwards. This allows the marking pen to be placed in just the right axial position, while still being very similar to a fully Cartesian (XYZ) plotter controls-wise.

Everything is powered by GRBL running on an Arduino Uno, which interfaces with its four steppers via a CNC shield and A4988 driver modules. Build info is available in tuenhidiy’s write-up, and you also check it out in the video below.

If you're interested in making your own version, PMD Way has you covered with a huge range of parts including Arduino nano-compatible boards, motor shields for Arduino, robotics parts, PCA9685 boards, jumper wires and more.
