What does it do?

Plotter robot arm

Recently the famous site evilmadscientist introduced the new art robot called Axidraw.I saw the robot in action and it is very similar to the robot I built in the 2015, called Cartesio, a 3d printed cartesian robot.

How to print a Pirate Hook with your Materia 101

Using a 3d printer means playing with some hardware but especially some softwares. In the tutorial of this week, the fourth tutorial of our series , Kris is going to introduce you how to work with Slic3r, a G-Code generator for 3d printers and basically a tool you need to convert a digital 3D model into printing instructions for your 3D printer. Slic3r is an open source software able to cut the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded so that you can reach good results.

The object you’ll be able to print with your Materia 101 is a pirate hook !

Follow the 12 steps on Scuola and print yours >>

Converting an STL file to Gcode to drive a CNC mill or lathe

As mentioned in my blog, "Multipurpose Mini Machine" DAGU wants to develop a low cost CNC machine kit. The models shown here will not be the final product, they are simply what I used for testing the quality of the components.

Part of the kit will be an Arduino compatible controller. Ok, I know, nothing new so far.

Drawbot software aims to do it better than the rest

There are plenty of drawbot projects out there, many of which come with their own special software in tow. While some of these packages are easier to use than others, [Dan Royer] is pretty sure he can do it better.

Looking for a fun and engaging way to teach STEM subjects in schools across the country, [Dan] developed a relatively simple drawbot which can be constructed by a wide range of age groups. While he is trying to get schools to purchase his robot kits, we’re guessing that our readers would be more inclined to build their own.

So what does [Dan] have to offer that might interest you? Well, he says he has developed some drawbot software that’s pretty darn easy to use. Rather than multiple applications generating machine-specific code, his software will transform your picture into a line drawing in one easy step. The app uses a traveling-salesman algorithm to generate drawings with nary a crossed line in sight before outputting the resultant machine instructions in easy-to-use GCode.

We don’t have a drawbot of our own handy to test his software out, so if you do happen to give it a shot, let us know how it worked for you in the comments.

$150 mural drawing robot kit

What does it do?

Draws murals by following GCode instructions and/or etch-a-sketch style commands

Knowing the length of each string and the distance between the servos gives us everything we need to use trigonometry to find the XY coordinates of the pen.  We can also do the reverse, which means we can find how much to change the strings to move from A to B. From there I added gcode support.  Lastly I wrote some Java apps to create a nice GUI.  If your arduino comes with the firmware already loaded then you don't even need to install the Arduino app. :)
