Based on the Musashi 8 software, with full support for the 4C™ eye system New model microcontroller runs at 8 Mhz for no hardware lag and the fastest code execution Enhanced power switching hardware for the solenoid Includes 12 fire modes: uncapped semi-auto, capped semi-auto, PSP auto-response, PSP 50% ramping, PSP 100% ramping, PSP burst, NXL full-automatic, auto-response, 50% ramping, 100% ramping, 3 round burst, and full-automatic Asynchronously monitors the trigger switch, using an interrupt based scan at 2 million times per second Gangster setting allows 3 different options for every fire mode, giving 36 different “breakout” style modes Adjustable ABS programming prevents first shot drop-off AMB (anti-mechanical bounce) and CPF (cycle percentage filter) algorithms help to eliminate mechanical bounce and switch bounce Power efficient software and hardware lengthens battery life Programming mode allows changes to debounce, dwell, loader delay, AMB, ABS dwell, fire mode, fire mode max rate of fire, eye mode, CPF, ramp start, gangster mode, bolt delay, and training mode dwell All settings are stored in non-volatile memory so they are not lost when battery is disconnected One-touch startup enables the marker to fire instantly Automatic 15-minute idle power down saves batteries 4 eye modes: delayed, forced with force shot, test mode with rate of fire indicator, and reduced dwell training mode with rate of fire indicator Low battery indicator hardware and software shows battery level each time the marker is turned on

Installation Removal and installation of the board in a Marq must be carefully done to ensure the electronics are not damaged. Begin by removing the grips from the marker. This will expose the entire circuit board. Remove the main wiring harness, the three mounting screws from the board, and then the board itself. Be aware of the trigger switch return spring mounting bracket which sits over the trigger switch. Place the return spring mounting bracket over the M8 Marq board’s trigger switch, then insert the board into the grip frame top first, making sure the wiring does not get pinched. Replace the 3 mounting screws. Plug in all the connections. It may be easier to completely remove the grip frame from the marker to replace the trigger return spring so you can insert it from the top. If the marker does not turn on, it may be due to a low or incorrectly inserted battery.

Eye Operation and Logic The eyes are enabled when the marker is first turned on. The eyes can be toggled by quickly pressing and releasing the power button. The LED will change colors to indicate the mode change. The Musashi 8 Marq board supports the 4C™ system, and will automatically detect whether a single eye set or dual eye set is installed at start up. If using a single eye set the LED indicator works as follows: Slow Blinking Blue Empty breech Solid Purple Ball in breech, ready to fire With a dual eye set the LED indicator works as follows: Slow Blinking Blue Empty breech, both top and bottom eyes unblocked Solid Blue Top eye set is blocked Solid Purple Bottom eye set is blocked Solid Teal Both top and bottom eye sets blocked The use of the 4C™ eye system allows for much faster rates of fire because it can anticipate the next paintball being loaded into the breech and start the firing cycle early, which negates the delay time found in the pneumatics of the paintball marker. The Musashi 8 software was written specifically to take advantage of this arrangement, and automatically uses the top eye set when the loader is feeding fast enough. It can also determine when the top eye set is blocked by paint or debris, and will default to using only the bottom eye until the top is clear again. Once the top eye is clear, it will resume use of both eye sets. If used, the eye system cycles the marker as fast as possible. During each shot the eyes watch for the bolt to return, ending the current firing cycle and starting another as quickly as the pneumatics allow. If the eye system is continually blocked (e.g. putting your finger in front of the eyes) and is unable to see the bolt return after every shot, the max rate of fire will be reduced to about 12 balls per second to prevent further chopping, and the LEDs will blink yellow to indicate the eye malfunction. Firing the marker with paint and air will utilize the eye system correctly, maximizing the rate of fire. When the eyes are off, the rate of fire is limited to 20 balls per second unless in fire modes 2 through 12, in which case the rate of fire is selected by the user. To determine if the eyes are working correctly, insert an object into the breech. Check to see if the LED changes from blinking blue to solid and then back to blinking blue once the object is removed.

Battery Indicator Battery indicator software and hardware are standard on the M8 Marq board. When the marker is turned on, the LED will briefly flicker red, yellow, or green to indicate the status of your battery. If it flickers red, the battery is exhausted and should be changed as soon as possible. If it flickers yellow, the battery may last for another case of paint, but it is close to failing.
