Here’s what Erin has to say about it: “Favorite thing about this robot is that it works with techninja42’s software ‘cncserver’. Making it a great low-cost and DIY alternative to the WaterColorBot. I’ll be using it with the iPad app I wrote.”
This is a small DIY 3-axis CNC. It basically consists of 8 plastic parts (1 part is duplicated, so only 7 unique parts), three micro servos. You will also need 1 zip tie, 1 rubberband, and a pen of your choice.
How to Build a Tiny 3-Axis CNC Drawing Robot
The Tiny 3-Axis CNC robot is a cheap, easy to build, extremely minimalistic but very capable little robot.1 This is the assembly guide for the version 0.29 robot available for download from Thingiverse. The above picture shows the fully assembled robot. If you have ever put together a lego set or built anything from Ikea, you should be able to build the entire robot in less than 5 minutes. I’ve uploaded step-by-step photographs with each “step” organized into a short slide show of pictures.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
