Easy CNC conversion of a small mill Why not a 3D printer? I think a lot more people have 3D printers than CNC mills and they're great tools. There's a bit of an overlap with a mill, but they both have their strengths and weaknesses. Comparing a mill to a printer we broadly have: Pros Cons 20 Amazing Creations You Can Make With 3D Printing - Hongkiat If you can print in 2D, can you print in 3D? Well, the technology is already here. You can print out 3-dimensional objects based on a working template, and they aren’t just for show. They actually work! Manufacturers can provide you with a template where you can print a broken part of a machinery, let’s say, a screw, rather than order then wait for a replacement to come in. Alternatively, you can make a model replica of an expensive car, like a 1960 Aston Martin DB5 in a 1:3 scale then crash and burn it for entertainment, like how the makers of the James Bond flick, Skyfall did.

G-code This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The main target is additive fabrication using FFF/FDM processes. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications, too. There are a few different ways to prepare GCode for a printer. One is to use a slicer like Slic3r, Skeinforge or Cura.

How to Fold Wet Origami Sounds like an anomaly, right? When I was a kid folding frogs, my mother gave me origami paper that was most certainly dry. But the works below by Vietnamese-American artist Giang Dinh were folded with one *wet* piece of paper. It's a technique called "Wet-Folding", invented by the great Japanese origami master Akira Yushizawa (pictured right). How to Get Almost Anything You Want Wouldn’t it be cool if you could get almost anything you wanted? It sounds like a dream, but to some extent, and if done correctly, it can be achieved. In this post I will share how I had one of the world’s most famous comedians and tv stars write jokes for me, saved thousands of dollars, and was able to get my hands on stuff before almost anyone else on the planet.

Literary gold mine for CNC millers From 1976 to 1983, Popular Science magazine, along with the American Plywood Association, ran an annual plywood panel project design contest for its readership. Often the winning projects were items of furniture, but that was not a requirement. A potter’s kick wheel and a folding plywood boat are notable exceptions. Driving 28BYJ-48 step motor with Pololu A4988 drivers I have always liked the 28BYJ-48 motor because of its power and price, it also supposed to very reliable since it is used in different types of air conditioners. Some information about the motor: This motor is very small but has enough power for most of the projects because it has a built-in 1/64 reduction gear. The result is a very small step of the motor which is 0,087890625 degrees per step. The reduction gear of course has its downiside which is the speed – you can typically drive this motor with maximum frequency of 100Hz which result in 100 steps per second which is 8,7890625 degrees per second.

Reprap development and further adventures in DIY 3D printing: Slic3r is Nicer - Part 1 - Settings and Extruder Calibration I have been using Slic3r for a few months now, it's coming along well and deserves lots more coverage, so here are a few notes and a very short guide to using it and what the settings mean - nothing difficult as it's already very easy to use and understand.In this Part 1 we will look at getting Slic3r running, calibrate the extruder and take a look at the Print settings.Part 2 will setup the printer, filament and print speeds along with doing some printing.Part 3 will experiment with low layer heights, hollow printing and any other features or limitations discovered.As of typing (6th Jan 2012) - Slic3r is at Version 0.5.7Please try it out, it's coming along very nicely and join in with the Slic3r RepRap ForumSlic3r WebsiteSlic3r on GithubDownload the package extract the zipped files and just run slic3r.exe directly from the directory, you don't need to setup anything unless you want to re-build it then you need the source from Github and citrus perl or Strawberry Perl. Rich.

My Paper Crane Here it is nearing the end of April and I forgot to blog about the Bag Of The Month bag for March! As you can see I ended up having a sad photoshoot in my car one afternoon while I was waiting to pick up my son after school. I have actually been using this bag all month long. How To Find the answer to almost ANYTHING. The Book of Google Yes it might seem like IT professionals are doing something very secretive and cleaver but often they are just holders of the Book of Google. Thanks to their incredible efforts to create the most universal search ever made Google and the tireless efforts of so many internet users on forums, blogs and websites there’s almost nothing that can’t be answered by a quick search. There is however a couple things this system of research throws up. First there is actually a right way and wrong way to use Google for research, the thing you’ve got to remember about the internet is that it’s driven on opinion so don’t just take the first link at the top of the search as a golden rule, make sure you scan at least the first five or so and keep refining your search terms often it’s not the obvious question that holds the answer.
