I have attached an image of which pins are connected and which are not.
The link you provided i did went through it but it didn't work. I used a M3 and M4 command to turn ON & OFF the spindle. I also set the pin 17 as spindle output but as i put the multi-meter to the pin i got nothing then i tried 16, 14,8...... no signal on them. I also tired the M10 & M11 commands but no luck. I have a feeling i am missing some very small or overlooking something maybe.
I have done a lot of research and come up lot of information but its just confusing or doesn't applies to my controller. Below are several links of my research
http://www.instructables.com/id/Using-Zen-Toolworks-CNC-with-Laser-Engraver/?ALLSTEPS--it shows a picture of the same kind of cnc breakout board as me being connected to a laser driver
http://buildlog.net/cnc_laser/mach_laser_power.html --he shows three ways to control the laser with mach3
--spindle as laser
--collant as laser
--using mach3 pwm to control laser
--he makes a good point about using the M11P1 & M10P1 to turn the laser on off instead of M3 and M5
---Example
----M11p# – Turn on the output the laser is on, where # is the number of the output
http://www.buildlog.net/blog/2010/07/mach3-laser-cutter-setup/ --therse are instruction on how to setup this using the M11p1 command
https://www.youtube.com/watch?v=_2gSFcrtt3A --this guys connected an ossiloscope to parallel port and display the pwm signal using s1000 commands
http://openbuilds.org/builds/co2-laser.565/ --complete build of how to make a co2 laser with mach3
--it also has circuit and information on how to connect the pin 16 17 to laser input
