I received my 2.8W laser last week and made a simple mount to attach to my DW660 mount. I used a flat piece of plastic and drilled it to match the 4 DW660 holes and added two holes for the laser.
I have fired up my laser and made some smoke focusing it but I have not tried to run any gcode yet. I am hoping to get to it this weekend.
Now there are three! I think we need to start a J Tech Laser thread!
