How to make vinyl cut PCBs. Design constrains for the circuit The circuits that you can cut on the Roland are limited by the width of the pen knife.

How to make vinyl cut PCBs

As a rule of thumb, anything that you can cut with a lot of time and effort with an x-acto can be cut by the Roland, but if there are things that are too small for that they will probably also be too small for the vinyl cutter. To use the cad.py software that goes with a lot of the FabLab machines, save your circuit as a .png. If you're using Eagle as your design software, you can output the layers that you want to use as a monochrome image, and use a 500 dpi to make sure you get enough resolution to contour the part.

You can also use this design constraint file in Eagle to make sure your traces aren't too close together. Use the .png as your input, and after clicking the cam button select .camm (for the roland) as your output. For the vinylcutter you only need one contour, check all of the contour lines to make sure that none of your paths are being skipped. Extra tips. Bird by reza. Bird ready for laser cutting or 3d printing. by hexleyosx. I will 3d print this bird some time soon and post pictures.

Bird ready for laser cutting or 3d printing. by hexleyosx

Sorry no .DXF but my Inkscape install is on the fritz and will not export anything useful. I leave that step up to anyone who wants to laser cut the bird. I Converted the original step file with free software into something usable. I used Free Cad to read the original step file. ReplicatorG to orient the .stl files. , Open Scad and Slic3r to convert the .STLs into 2D .SVGs, and Inkscape to layout.

For laser cutting the original took 2mm material but the bird can be scaled for other sizes. Bird by reza. Wind Power & Renewable Energy Science, Turbine Kits, Lessons & Workshops. So What’s a Practical Laser-Cut Clip Size? I’ve previously shown for laser-cut elastic-clips for comb joints what the equations are for calculating maximum bending stress and operating force, using the distance that the clip has to deflect in use as the starting point.

So What’s a Practical Laser-Cut Clip Size?

I also explained how a tapering clip profile was preferable to a straight one. This time I’m going to share an example of a practical clip geometry that I’ve been using regularly to hold small parts together in 3mm acrylic. While the clip is useful as a component of other parts, it’s helpful to see how it is used to make something practical, so I’ve also made a clip-together box that can be completely made from laser cut acrylic, with no other parts or tools needed.

Both the clip geometry and the box are available on thingiverse for you to download, use and remix. As a measure of how robust the clips that hold the box together are, we’re now also producing some Raspberry Pi cases using a derivative of the box design above. Laser-cut Lattice Living Hinges. AKA: Snijlab-style living hinges, Sninges, Laser cut hinges, or my prefered title: Lattice Hinges Flexi-Acrylic Test by Solarbotics, on Flickr After this style of hinge popped up again, this time on Makezine, I was having a look at the linked project guide and at how they worked and I realised that a bit of mathematical modelling could lead to better designed hinges.

How to Build a Tiny CNC Drawing Robot

The above are nearly all the tools and parts you’ll need to build your own itty bitty CNC drawing robot. If you have a 3D printer and a spare Arduino, the rest of the parts should cost you around $20. Right now this robot only has two axes, but in the very near future I hope to add either a Z axis or a pen lift. Without further ado the tools needed are: Tools One small precision screwdriver Parts 2x Micro Servo Motors6x 3D printed parts, downloaded from Thingiverse1x rubber band1x pencil You’ll also need an Arduino, some wire to connect your servos to the Arduino, and a USB cable to communicate with the Arduino.

Assembly Step 1: Print parts All printed parts There are only six printed parts necessary for this mini-CNC. Step 2: Assemble the X axis stage Grab your Micro Servo, the little screw that came with it, the flat gear (really, pinion), and the X axis stage. Analog Feedback Micro Servo - Metal Gear ID: 1450 - $14.95. Robotics & CNC / Robotics / Analog Feedback Micro Servo - Metal Gear Analog Feedback Micro Servo - Metal Gear Description Description- It looks like a micro servo, it acts like a micro servo, but it's more than just a micro servo!

Analog Feedback Micro Servo - Metal Gear ID: 1450 - $14.95

We got a factory to custom-make these quality metal-geared 'micro' sized hobby servos with a twist - the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analog input such as those on an Arduino, to get the servo's position. That information can be used in robotics to improve stability or even allow 'recording' of servo motion. Mini-CNC v0.18 by MakerBlock. Mini 3-Axis CNC v0.29 by MakerBlock. UPDATE: Check out my drawing robot blog for the software to run this robot!

Mini 3-Axis CNC v0.29 by MakerBlock

Step by step instructions for v0.29 here: This is a small DIY 3-axis CNC. It basically consists of 8 plastic parts (1 part is duplicated, so only 7 unique parts), three micro servos. You will also need 1 zip tie, 1 rubberband, and a pen of your choice. Join my drawing robot newsletter or check out my blog for more information, build instructions, updates, and improvements.
