The aim was to design a laser cutter as economically as possible (~4500 euros).
During my research, which included studying other open source projects, I became aware of a new kind of laser — a diode laser — which can move through optical fibers.
This enabled me to have a free-standing multifunctional head while also making the machine smaller with the most up-to-date technology.
Using a a small diode laser gave me more working space, consuming less energy, while at the same time being more precise and less expensive.
The process was amazing. I designed 7 versions of the machine, each one building on the previous stage, resulting in a better and less costly machine.
I succeeded in finding a good solution for the movement of the axis.
The machine design includes electronics — design, implementation, and control — as well as programming.
The machine is controlled by the GBRL CNC program.
I received the laser only yesterday and am still waiting for some material to arrive in Israel. This project will continue to develop over time.

Open source laser Machine, but in the same time it is a collaboration with laser company
Study from the open source laser cutter I found the almost half of its price goes to the machine construction.
Because of its use the construction need to be from strong and laser prof (as much as possible).
Therefor the Machine design was very importent I tried to optimize the parts and by that to lower the cost of the machine, 7 different designs till I came to the last one.
actually now when I know that I can use Scobond for the machine skin that the laser wont damage it I am working on new design to mill a Scobond sheet and build with it more parts of the machine
- The machine Electricity will be Fabricate using Fabduino
- The scobond Sheet will be mill
- The Axis "wheel" will be fabricated like the Lasersur solution
- I am trying to make coupling
Building it

- – - What more – Mill the scobond boards when they arrive to cover the machine
- – - study and make a controller for the Civan's Laser
Problems – My 1/64" drill bits are destroyed so I need to find a place to mill my fabduildo, motor controllers …
Some electronic components havent arrived yet
The Z T P motors haven't arrived yet

Building the RepRap 3D printer
New Design by Sefi
5 Axis Laser Cutter – Machine Design
For Designing my Machine I used the Open Source Laser cutter project Lasersaur
This project is amazing and they have great solutions in it that I adapted,
The differences are that i build 5 axis machine, they have only 2 axis, They use CO2 laser with is huge need to have cooler solution and optic lenses, I am going to use a prototype of a company called CIVAN witch are creating the smallest laser using diodas, their laser consume 0.01 times less anergy and it is 100 times more paresis, the laser is going throw optic fibers there for no need optical solotion
The Machine can be smaller in size than the Lasersaur project because of the differences of the laser
But the high Z axis is the interesting place, to move the whole bace I needed lots of forces for it but the machine could be sorter, at the end I decided to put the Z axis on the Bridge using the MTM solution, yes the machine will be taller but need less efforts to move in the Z axis.
If you want you can download the 3D model of the machine and give me feedback to ohadme (at) gmail (dot) com

After playing with the dc controller and a computer fan (which can move only to one direction – to it frizzed each time it moved to the other one) , I wanted to use the stepper controller but I had some problems, couldn't send to software to the controller
My Idea was to take an old radiotape and to control the Tape speed, when I open it and I thought that the motor has 4 pins I thought that it is a stepper motor, but when I tested it I became to know that it is a DC motor with controllers
therefor I hacked and plug the controller some problems appear but at the end it worked,
the direction changes kill the tape casetes, so I made a new code but for a reason couldn't reupload the software any more
I know that you can't hear the voice changes the magnet of the speakers making the problems

Using 123D app scan of my face to 3d print it
I need to close all the holes in the mesh I got.
Than to operate the Makerbot I had some problems at the beginning do to the material place – It was lower than the machine and and the extruder couldn't take the material in it
Last year my group and I hacked the Shopbot and build a 3d multi material depositing building printer

]]>In this week I mill the secret boards easily with FabLab Barcelona Modela
It was interesting and easy way to use FabMoudel
Than We needed to boot the controller
We have done it in C
and in Ardoino – Ardoino was much easier
]]>This week I came for a visit in my home FabLab
When I arrived I saw the last week assignment the people have done with 123D Make and I just wanted to do the same
