WARP FEED
INSTRUCTIONS
Overview
The patent pending Warp Feedis the world’s first universal force-feed system. It is a “friction drive,” meaning the drive wheel has
friction discs instead of pockets so the balls can never jam or break. When you stop shooting, the feed wheel will harmlessly slip
past the balls in the system and then pause, waiting for the next shot. When a “fire” signal comes from the gun, or when the sensor
determines the gun has been fired, the motor will spin the feed wheel and push balls into the feed tube. The feed wheel will
continue to spin for a preset amount of time that is adjustable. The system uses special MOSFET technology that eliminates the
need for an on/off switch. The battery only feeds power to the system when it receives a signal to feed balls. Disconnect your
battery for very long storage.
What you need to make it work
When using the Warp Feed the balls are being PUSHED into the breech. Because of this it becomes very important that you use
the specially designed ParabolicPowerFeed Plug supplied with your unit if you are mounting it on aPowerFeed gun. The standard
PowerFeed Plug will NOT work at all with the Warp Feed. It is just as important that the barrel you are using has a good ball detent
system or nubbin. Test this yourself by pushing a ball past the detent; if it offers little or no resistance, the Warp Feed may double
feed balls or, worse, cause the second ball in the tube to get chopped.
Jumpers
There are two sets of jumpers on the circuit board, which can be found under the cover plate on the back of the unit. The first
jumper has three positions labeled “–” (Negative), “+” (Positive), and “sens” (Sensor). If the gun sends a ground signal or you are
interfacing to a switch mounted on the gun, select the “–” position. Select ”+” if the gun on which you are installing the system
sends a positive voltage pulse every time the gun is fired or if you have an external vibration sensor plugged into the input jack.
The “sens” position activates the built in sensor that reacts to the gun’s vibration when fired and requires no further interface. This
setting works best on guns with blowback; there may have problems with guns that don’t have enough
vibration. Leave this jumper in place for guns using an external sensor; it protects your transistors from
blowing up from high voltages that can be generated by hitting the external sensor. The second
jumper has four positions and the unit comes with jumpers
in a non-functional storage position on all four. These
jumpers control the length of time the feed wheel spins
after it gets the signal from the gun. The more jumpers you
install the shorter time the wheel will spin. It does not
matter which ones you install first because they all shorten
the timing an equal amount. You should set the timing so
that at your maximum firing rate the wheel spins continu-
ously. Setting this to the minimum timing to get reliable
feeding will maximize battery life. Store the jumpers you
remove in a safe place in case you need them.
Vibration Sensor
Some versions of the Warp Feed come with either an internal or externally mounted vibration sensor. This sensor allows you to use
a variety of non-electronic guns with the Warp. It senses the vibration and rotates the feed wheel. We have included a sensitivity
adjustment on the circuit board since all guns vibrate different amounts. This is a one-turn potentiometer that varies the offset
voltage and makes the sensor more or less sensitive. To set the adjustment, unscrew the gear cover plate and find the blue
potentiometer. To set the system to its highest sensitivity, turn the potentiometer clockwise until the motor spins, then back off until
it stops. This should be your most sensitive adjustment, but will likely spin the motor when you don’t want it to. Fire your gun and
continue to rotate the potentiometer counterclockwise until the Warp starts missing shots. Your best position will be about half way
between most sensitive and missing shots.
Run In
The electric motor has carbon brushes that spark when new. The sparking creates electrical noise that looks like the sensor is
sending a fire signal. The motor may run continuously when using the sensor system on a brand new Warp adjusted to maximum
sensitivity. This will go away after a short run in period. The quickest way to break in your brushes is turn your sensitivity adjust-
ment clockwise until the motor spins, then back it off a little. Let the motor spin as long as it wants and when the brushes break in it
will stop on its own in several minutes. Do this several times and you should be ready to go.
Maintenance
Your Warp Feed should require little maintenance, but you should do the following to keep it in top shape:
1) Lubricate the feed wheel, shaft, and gears with any good quality grease; 2) Replace the oring drive belt once or twice a year to
maintain reliable operation; 3) Occasionally clean the inside of the case to prevent build up of grime that may interfere with the
gearing.
