I bought one of those low cost laser machines from China with a 2.5 watt laser diode.

I'm learning gcode and I am interested in starting off (for awhile) making multiple passes on 3mm plywood to completely cut out shapes.

The controller board that came with my laser doesn't support PWM, so I would like to find a controller board that I can flash a version of Grbl onto and control the laser power/intensity via PWM.

Any suggestions would be welcome!

Thank you...
