Introduction: Projecta - the DIY Desktop CNC Machine for PCB Prototyping
Projecta is a desktop CNC machine that engraves an ink layer on the surface of the board to make your beautiful PCB designs ready for acid etching.

Step 1: Why Projecta?
Buying an ordinary desktop CNC machine will cost you a lot of money, so we designed the machine with our special spindle to make the price so affordable for everyone.
Plus, in comparison with other PCB methods, Projecta will always be on top of the competition, as it doesn't require any special tools or materials to produce, and so the running cost is always a BIG ZERO.
The machine is directed to all those who make PCB starting from students and home-inventors to professional engineers.
Working with old-school methods for PCB fabrication, you will take a lot of time working on your PCB, developing a film or transferring the ink, which may take a "while," while Projecta can make your PCB in minutes.
From now you don't have to develop films or count seconds on the laminator, the iron is back to its original job of ironing clothes. Give the PCB to Projecta and it knows what to do.
Projecta is quiet and clean, no effort that will exhaust you in the clean-up process after every PCB. Print and Go with Projecta.
· No need to feed it
No conductive ink for the 3D printer, no photo resist films and developers, no Laminators, or any other material that you always have to buy to make a PCB. All you need is a simple marker that will last for a large number of PCBs
· Auto lock
To ensure safety and stability Projecta has an auto-lock that will lock the drawer when it's working
· Print and go
Most PCB methods require a lot of steps, a special place to work in, experience with chemicals...Etc.
Projecta just requires a USB cable and some clicks on buttons. Simple and easy to use!
· USB interface
Plug and Play!
· Stand alone
Projecta's software will deliver the print jobs to the machine to store in internal memory, allowing the machine to continue without being tethered to a computer.
Step 2: Using Projecta
Here's a video showing the whole process of Projecta in real time.
We cover the PCB board with any available metallic marker (instead of photoresist films) and inside the machine there is an engraving bit connected to a mechanical piston which applies pressure while moving in 3 dimensions to engrave the ink layer rather than the copper layer and shape your circuit design on the PCB to produce the same quality and resolution achieved by photoresist dry films in very fast technique (few minutes) then only etching step is left and you got your design.
1- Finish your design on any PCB design software and export Gerber files.
2- Use any tool you are familiar with to generate the engraving code.
3- Color your PCB with the metallic marker and fix it well on the drawer.
4- With the software we will provide you with, download the Code on Projecta. Our special spindle will engrave the design in minutes and when done you will be able to open the drawer and get your PCB.
Step 3: Technical Specs
Projecta is made of plastic so its body is almost weightless. Stepper motors and axis are inside the box.
· Projecta works with USB interface for maximum ease of use.
· PCB minimum specifications are as follows:
o Minimum trace width: 0.2mm
o Minimum clearance: 0.3mm
o Allowed PCB thickness: 0.2mm-4mm
o Allowed PCB layers: 2 layers
· Working area: 200mm * 150mm
· Machine dimensions: 35cm*30cm*25cm
