Making your own PCB boards for DIY electronics projects is not difficult. Doing so as a DIY project is extremely handy and allows almost anyone to custom design one-off, or small batch circuit layouts relatively quickly and cheaply, without the need for the volumes or costs involved in using the services of professional circuit board manufacturers. With care, DIY PCB project results are usually of extremely high quality and are very satisfying. Even more interest can be added to projects when printed circuit boards are combined with CNC cutter designs for shaping of the circuit boards.

There are various different methods for making PCB boards. Each method has various pros and cons, with most considerations being linked to cost, quality of finished product, accuracy required for fine circuits and availability of chemicals and materials.

This Instructable will show you how I built my CNC milling machine. I know a lot of CNC dreamers do not have the knowledge or tools to build a full metal machine. I still think and hope this Instructable inspires you to make your own machine. I include all of the necessary steps I went through in designing and building this CNC milling machine. All of the drawings I used to build my machine will be available.

I bought a CNC machine some time ago and I was never happy with it. It used a traditional parallel port controller and of course no modern computers have those. So it was always a point of frustration. I used an old Pentium based computer and ran LinuxCNC on it for a while but was still not happy with that. So I started looking for another solution. I decided that I would try to put together an Arduino based controller and try to use USB to communicate with it.

The Nomad 883 is a ready-to-run CNC Mill that’s at home in any environment.

With The Nomad 883 we’ve taken the guesswork out of operating a CNC machine. Everything you’ll need to get started is included – software (for Mac and PC), cutters, cables, even a starter pack of material. You’ll be cutting parts out on day one. The Nomad 883 is fully enclosed to control the mess and limit the noise. You can get a Bamboo enclosure for a home or studio, or a durable HDPE enclosure for the shop or garage.

This project is a small CNC mill that can be assembled from store-bought and laser-cut parts for about $800 without machine tools. (If you have access to a shop with a chop saw and a drill press that’ll be helpful, but you can get by with a hacksaw and some wrenches.) As pictured it has about a 4″ x 6″ x 1.5″ working volume, but it can easily be expanded and modified.

Ian D. Miller made a Raspberry Pi powered laser engraver using two old DVD RW drives. He writes:

engravR is a Raspberry Pi powered laser engraver built primarily using two old DVD RW drives. It was built following the following tutorial: http://funofdiy.blogspot.com/2013/10/a-raspberry-pi-controlled-mini-laser.html Note that I did make changes to the code given there in order to allow remote engraving and to be able to read the kind of GCode that GCodeTools generates. It is available at the above GitHub link.

Choosing the proper CNC lathe for the job is essential. Your lathe will be producing numerous parts, the quality of which will depend upon the standards the lathe is built to. The correct lathe is an investment. Therefore, choosing a CNC lathe should not be a decision that is taken lightly.

Microprocessor-Controlled CNC Lathes

When space and electricity are at a premium, a microprocessor-controlled CNC lathe can be remarkably useful. Rather than receiving constant instructions from an attached personal computer, these lathes can be fed their instructions once from a remote computer or a disk. Afterwards, adjustments to the design can be made using an integrated control panel. Efficient but cost-effective lathes utilize the 6502, Z80, 8086, 8088 and 68000 processors. See “Energy Conservation Considerations” later in this article.

Upgrading a Microprocessor-Controlled CNC Lathe

It is not always best to choose the highest-end model when you select a microprocessor-controlled lathe. For example, many lathes utilise the Motorola 68000 processor. Other common implementations utilise a Hitachi, Signetics or Toshiba variant. In the event that this processor is socketed, as it often is, you can quickly and cheaply replace the chip with a newer model. It is important that the replacement chip you choose is pin-for-pin and instruction set compatible with the originally-installed part. Read the rest of this entry »
