Makerspace i3Detroit was the recent recipient of a free yet non-functioning CNC router. While out of commission when received, the device’s mechanical components and motors appeared to be in operational condition, plus it had a large work surface. The decision was made to get the CNC up and running for now, with the eventual goal of […]
It’s easy to see that painting takes a lot of skill, but few really understand how much skill is involved like John Opsahl, who created the “If Then Paint” CNC canvas painting machine. In order to produce the proper paint strokes, his device implements full six-axis brush control, moving not only in the X/Y/Z coordinate system, […]
Jiri Praus enjoys using brass wire for his freeform sculptures, but isn’t a fan of making the same bends over again. To solve this problem, he designed a CNC machine to handle that task for him. His device features a series of rollers to straighten out the wire, with a stepper-driven puller that utilizes a […]
Inventor Artist Darcy Whyte wanted a drawing robot that was light enough to carry around, and could quickly produce drawings. Naturally, he turned to an Arduino Uno, along with a CNC shield and a trio of A4988 stepper drivers. These control a NEMA 8 and two NEMA17 stepper motors in a gantry-style artistic setup. The […]
If you’ve been waiting for a new way to generate geometric art, then be sure to check out the Cycloid-O-Matic from InventorArtist Darcy Whyte. This three-axis cycloid drawing machine is something of an update on the classic spirograph toy, but instead of (only) using an arrangement of gears, it incorporates stepper motors to create smooth […]
Arduino boards running GRBL software have long been used for CNC machine control, but usually you need to choose between having a router or laser cutter. This project, however, is specifically designed to accommodate both with a modular carriage system. Build-wise, it’s a fairly standard XYZ gantry CNC — with a frame made out of […]
For an easy plotter design that you can build with only simple hand tools, be sure to check out this tiny project from Mr Innovative. The machine features a pair of stepper and lead screw assemblies to maneuver a pen in an X/Y plane, along with a clever string and servo setup to handle retraction. […]
Even if you don’t have access to fancy tools like a 3D printer or CNC router, that doesn’t mean you can’t make something interesting. James, using only a “hot glue gun, some scissors, and a screwdriver,” was able to construct a rudimentary drawing robot that marks paper with a sharpie. Two CD drives were creatively modified […]
When you see a plastic ruler, you wouldn’t normally assume it was destined to become part of a CNC plotter. Maker “lingib,” however, realized their potential to be combined to form plotter arms, in this case actuated by two stepper motors. The resulting build can expand and contract the resulting shape, allowing a pen at […]
Farmbot is the first open source cnc farming machine with the aim to create an open and accessible technology aiding everyone to grow food and to grow food for everyone. It runs on open source hardware like Arduino Mega 2560 and involves a community of contributors on the wiki and forum where you can find […]
