| Aimtrak recoil issues... (solved) |

So I picked up everything i need for a couple of aimtrak guns with recoil. I installed everything per the pdf on the ultimarc site. But the solenoid is not working. Help! Some other details for whoever has experience with this: -I installed the latest aimtrak utility program (1.9), updated the sensor module's firmware to 9.15, and was able to calibrate the gun just fine. No issues there. The tracking and trigger work flawlesly. -Yes, I cranked up the solenoid strength setting on the utility program, and of course, uploaded the changes to the module. -I am using a Kodak 36V 1.7A printer (?) power supply. From the power cable, I connected the "inside wire" to the V+ and the surrounding "outside wiring" to the V- on the trigger PCB, which is how the polarity is set on the coaxial power plug (which of course I had to remove). SHould I just try inverting these? -I touched up some of the soldering just in case... because the solenoid actually fired ONCE (and gave me a heart attack btw). I was aiming at the screen at all times....which brings me to the next point. -When the instructions say, "you have to aim at the screen for the solenoid to fire", I'm assuming that as long as the sensor on top of my screen can "see the gun", it should work, right? I don't need to be running an actual game, I don't think... -If I touch the solenoid directly to the + and - of the power supply cable, it does fire. -Just to be clear regarding the two wires removed from the old trigger, the one going to the side trigger goes on G and the other one coming from the sensor module goes on T on the new trigger PCB, right? -The Aimtrak utility is picking up a "strong" signal strength from the module, when I click on the tab to check for that. ANY help would be greatly appreciated. |

As long as you can see the signal onscreen it should fire the solenoid. It looks like you have a newer gun as the inside is a little different than mine but the setup looks correct. You could try flipping the + and - on the solenoid though I know from experience it's a pain to remove the solder on that small pcb and it's a short wire to cut and re-splice. I'd shoot Andy an email and see if he has any ideas. I found the connection in the little white connector on the light sensor pcb to be suspect too, it's hard to push in without bending and making sure it connects well, might want to double-check that. |

I've concluded that it has to be a faulty solder point on the trigger PCB. I built the second gun being extra anal about my soldering, and the recoil works flawlessly. I'm getting a good solid kick with the 36v....thanks 8bitmonk for the suggestion. So i'm just going to redo the faulty one completely... In other news, when i pull the trigger 5-6 times in a row real fast (about twice per second), the power supply's led light goes out, and stops providing power to the solenoid. I have to disconnect and reconnect it to have the led turn on and provide juice once again. If I stay at around one click per second, it's fine. Sigh.... Thoughts? Suggestions? |

This is why the recoil power supplies are 5A@24vDC. |

I'm trying to find 36v charger/power supplies on ebay with 5A but It's hard to make sure I'm getting the right thing (battery chargers? Scooter chargers? Ac/dc converters...?) This is the best I've seen 36v 4.16a. But it is almost 5A. Is that enough? |
