I am currently retrofitting a cheap chinese laser with new driver boards so i don't have to use their moshi draw program. i have now got the x,y working fine and am looking to connect the laser board. before i fry my computer i am just trying to find somone who can help me out.

r }-these go to potentiometer on control panel to control laser power

grd originally went to main driver control board
+5v
i currently have both grd and +5v disconnected and the laser still test fires by test button.
k,k and grd,5v both lead to 2x opto coupler on the laser board. i'm not sure the best way to connect the laser to my breakout board to control using pwm on mach3. i think it used to use the grd and +5v.
if you could point me in the correct direction on what connections to make.
