Guerrilla guide to CNC machining and resin casting, volume II

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. 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.

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> It most often happens when profiling inside a closed sketch where the radii is close to the diameter of the cutter. Recently I was profiling several cutouts that were exact copies of one another just rotated around a central point. It seems that the error is coming from the entry point. This won't work in every case, especially if the pocket is very close to the size of the cutter or made up of tight curves but for the most common cases it should work fine. My interests in CNC and machining developed over a period of years in a very organic way. But it doesn't work here. 5). The cutting process works like this:

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 youre just considering it, but where do you start? There are many advantages to owning a CNC router. Yes, you can build a CNC router that is just about as good as any other for a fraction of the retail price, and its not that difficult! There is also a great deal of flexibility when you design and build your own machine. There are many reasons people want to build their own homemade CNC router. My Experience When I first started to design and build my first homemade CNC router, I had it all figured out in about a day. Do I really need ball screws or will ACME screws work fine? Luckily, some of my questions I could answer with my mechanical engineering background. So I researched the internet. Maybe you dont want to design your own, but still want to build your own.
