How to Build a Tiny CNC Drawing Robot

How to Build a Tiny CNC Drawing Robot

The [below] are nearly all the tools and parts you’ll need to build your own itty bitty CNC drawing robot.1 If you have a 3D printer and a spare Arduino, the rest of the parts should cost you around $20.  Right now this robot only has two axes, but in the very near future I hope to add either a Z axis or a pen lift.

Uses the Adafruit Analog Feedback Micro Servo!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. “CNC Drawing Robot”?

    You know, back in the day, they were called “plotters”…

  2. Well… I did post the designs on my “PlotterBot” website…
