Does anyone have a wiring schematic for adding a laser to a cnc router.
I am running mach 3 which will probably be controlled via ttl to ground. I do not have an ethernet card so I believe pwm is not possible.
I am running a gecko g540 card.
The ttl needs 5v which I believe I might have to supply that with a buckboard off the 48v power supply.
The only control I have over laser power is the hand adjustable pot which is used for focusing so I don;t believe I can do greyscale.
Any help is appreciated.
Thanks
