My friend Hirotaka and I worked hard to develop an affordable easy to use desktop laser cutter for about one year. Then finally, our ideas and effort were fully realized.
People can be freely modify our software and hardware to expand the processing area and add such as adding additional functions.
-1.6 watts diode laser
It adopted 1.6 watts diode laser for the laser parts. The output is strong enough that it can cut 0.079inch (2mm) of material.
We adopted open builds V-slot (http://openbuildspartstore.com/) for our mechanical parts, therefore it is simple and easy to assemble.
- The control board
The control board used Arduino Mega.
(Arduino - ArduinoBoardMega2560)
Arduino Mega’s program is based on GRBL (Bengler: GRBL)
For the Laser diode, we use Blue Laser Diode 1.6 W in TO56 Package by OSRAM Ltd.
Laser diode is cooling by the heat sink and fan, also it reduces the tempersture rise of the laser diode.
And, ｔhe cover for blocking the light of the laser are mounted on the laser module.

Smart Laser Mini’s axises are OpenBuilds’s V-Slot Linear Rail(20 x 20mm)とDelrin Mini V Wheel. By adopting V-Slot, the number of parts will be reduced and the mechanism will become simple.
Smart Laser Mini is used 5mm thickness acrylic for marerials such as Plates.

The controller software is based on the GBRL (Bengler: GRBL) which modified the Lasersaur (Lasersaur Manual). The computer and controller are connected via COM (USB), and the communication is working by G-Code.
PC Software also based on Lasersaur.
This PC software is Server-client system.
Start the server software on the PC that you want to work on and start a browser session as a client on the same PC to access the server software.
Also, it is possible to perform server and client software on different PCs and control them through the Internet.

As for the Smart Laser Mini, there are two types of working techniques.
- The vector cutting
The vector cutting can cut along the outer shapes also It can be created in SVG or DXF format.
2.The raster engraving
Raster engraving is for impressing an image while horizontally scanning just like filling.
Raster engraving can be put into practice by pasting SVG, PNG or BMP format images.
・Work with Raspberry Pi
Smart Laser Mini also works with Raspberry Pi. As you can see the following blog, we mounted Raspberry Pi 2 and 7inch monitor to the Smart Laser Mini.
・Raspberry Pi 2 , Monitor and Desktop Laser Cutter
We created a Japanese pubric group called “ Share your work using the Smart Laser Mini”
The group members post and share own work in Facebook. We will create in English version soon.
