Guerrilla guide to CNC machining, mold making, and resin casting

Guerrilla guide to CNC machining, mold making, and resin casting
Table of contents: 1. Introduction A quick overview of what this guide has to offer to DIYers looking for a CNC mill - and to those who have already settled on low-cost 3D printing or any other rapid prototyping technology out there. 2. Setting up a CNC mill Pointers for selecting a low-cost, hobbyist-friendly CNC mill, stocking up on tools, and keeping the whole setup in great condition for many years to come. 3. Tips for finding the right CAD and CAM software - plus a quick but in-depth tutorial on three-dimensional modeling. 4. Advanced, workshop-safe methods of producing durable, high-performance parts of almost any kind - from tough rubbers to bullet-stopping composites. 5. Advice on how to build a library of prefabricated components for all sorts of electromechanical work. 6. A no-nonsense primer on mechanical engineering, gear design, and power transmission layouts. 7. The sort of things you probably need to know to avoid setting yourself on fire. 8.

Big Easy Driver stepper motor driver An Open Source Hardware Stepper Motor Driver Description: The Big Easy Driver is a stepper motor driver board for bi-polar stepper motors up to 2A/phase. HeeksCNC « The Hell Ya Beller HeeksCNC can be finicky about profiles. Often I've found that a sketch which should be easily profiled won't generate any gcode at all. When I look in the console, I find an error like this File "/usr/lib/heekscnc/kurve_funcs.py", line 247, in profile raise Exception, "couldn't offset kurve " + str(offset_curve)Exception: couldn't offset kurve <area.Curve object at 0xb6f4bf2c>

3D Printed Raspberry Pi Compatible Open-Source Humanoid Robot Meet Poppy, the beautiful little 3D printed humanoid robot created by Flowers Lab. Poppy has been designed as a robotic platform for research, art and education. It is a open-source project and its aim is to be as simple, flexible and affordable to the masses as is reasonably practical.

My adventures in CNC robotics My adventures in CNC robotics Introduction I'm a computer geek by day, but I have always dreamt of something more than just writing code: I hoped to make things that interact with the physical world. To make it worse, I couldn't convince myself to take the now-popular route of buying the prefabricated robotics kits and putting them together in one of several predetermined ways. Ultimately, I just wanted to learn how to make stuff. Polar Plotter on Arduino and MakerBeams by roxen The project A polar plotter is a plotter with a rotating, extendable arm. Its characteristics differ greatly from those of a traditional plotter, which in most areas have a superior design. You could say the polar plotter is more portable or something, but mainly I made this one because it was more of a challenge. Here's how it looks:

EMC Documentation Wiki: Cam [Note: This page is currently being refurbished. The work includes additional entries, reorganization, addition of version/date stamping, addition of some annotation. About 1/3 of the work is done. Torsion Box Table Initial module Torsion Box Table Initial module One is required for each table. This assembly is used to mount the chain ends (overlap designed at the ends). This is also a great option as a standalone table top/workbench if stiffness is needed. Included:

Guerrilla guide to CNC machining, mold making, and resin casting Guerrilla guide to CNC machining, mold making, and resin casting Okay, still interested? Let's dive in, then. The first "proper" section of this guide deals with shopping for a mill and understanding its operating characteristics; picking the appropriate cutting tools; and monitoring the performance of your setup to achieve perfect results every time. Again, if you're using another manufacturing process and are interested strictly in the CAD tutorial or the resin casting bits, feel free to skip ahead.

Live Plotter on Arduino and MakerBeams by roxen The project This is an Arduino/Java project that lets you draw live on paper from an html5 canvas. This is a high level schematic: Homemade CNC Router The Builder's Guide (FREE!) This guide is still under construction! Sections Introduction My Experience About Kits and Plans About This Guide The Guide Starts Here IntroductionSo you've decided to build a homemade CNC router or maybe you’re just considering it, but where do you start? Calibrating Feeds and Speeds with Carbide Microtools The first question that most people ask when using carbide mini and micro tools to cut wood (and other soft materials) for the first time, is, "What are the best speeds and feeds?". What they really want to know is, "How fast I can cut without breaking a bit? What are the optimum cutting conditions with my equipment?" If you are primarliy cutting metal, in most cases, the process of selecting the proper speed (RPM) and feed-rate is relatively straightforward. If you are cutting woods or plastics, the world is not so kind. Nonetheless, it is possible to arrive at an optimum combination of speed and feed reliably and repeatably without experiencing too much brain-death.

CNC 3020 router from eBay » Makerflux Earlier this year I had the urge to get back into an old hobby, Electronics! When I was younger and living with my parents I had my own workshop. In this workshop I would prototype some ideas on breadboard and when I was finished would design a printed circuit board. The traditional method of etching a printed circuit board is using a ultraviolet light box and chemicals to etch away the copper. However I no longer live with my parents and have no access to a workshop. I am a proud dad with a small office in my house.
