Sometime ago, i've built a small CNC Laser engraver, but it doesn't satisfy me, both the electronics and the mechanical...
After a while i've started to design a new control board for the Laser, this time i want all the electronics on a single PCB, both the movement control and the current driver of the laser.
The first step was to design the circuit : I've used the standard GRBL pin assignment, the LT3083 to drive the laser and the stepstick to move the motors.
NOTE: This is a REV1, I have already identified an improvement to do ...
Schematics (REV 1):
PCB (REV 1):
With these files I have made the PCBs:
Then I've soldered all the components and this is the result:
(In the next build i'll use the vslot to build the mechanics)
Update:
With the need to generate the GCode for the laser directly from an image, i've started to write an extension for Inkscape (http://www.inkscape.org/).
Installing:
Step 1) Download from "Attached Files:" (at bottom)
Step 2) Extract the archive and simply copy all the files in the folder "Extensions" of Inkscape
Code:Windows ) "C:\<...>\Inkscape\share\extensions" Linux ) "/usr/share/inkscape/extensions" Mac ) "/Applications/Inkscape.app/Contents/Resources/extensions" for unix (& mac maybe) change the permission on the file: chmod 755 png.py chmod 755 raster2laser_gcode.py chmod 644 raster2laser_gcode.inx
Usage:
Step 1) Resize the inkscape document to match the dimension of your working area
Step 2) Draw or import the image
Step 3) To run the extension go to: Extension > 305 Engineering > Raster 2 Laser GCode generator
Step 4) Play!

Special Notes
1) This is a REV 1 of the board.
2) English is not my native language, so sorry for my poor grammar...
