I read many posts and now I had finished my first mini Lazer Cutter.
The design is simple and reliable ( u can see the video )
It is using Arduino Duemilanove + GRBL (0.8c) + 100mW blue/ violet lazer with external battery power supply (5V)
Drawing program is inkscape + gcodetools, gcode sender is Unversai G Code Sender
I want to share with u but it is really difficult for me to explain it in english…
I just want to share some experiences, or, may be u can ask me…
Also, most of the technical things (especially about GRBL) u can find in the following articles.
