Emag auto-firing

[fhawkeye]

Emag is firing automatic bursts in semi. I know its a problem in the lowers but I can't seem to adjust the trigger in any way to keep it from happening. any ideas? the board is an xmod 1.7

Is the sear bouncing of the trigger?

[fhawkeye]

negative, the trigger isn't touching the seer. I guess a better way to explain this is that there is a "sweet-spot" in the trigger pull where at some point when the trigger is swung into the magnetic field the solenoid goes crazy and fires full-auto.

Try adj your trigger magnet closer to the hall sensor. You might be right on the verge of activating it and not activating it which is causing it to go stupid.

If that doesn't fix it. Do a general ck on your on/off orings, sear, bolt and bolt spring.

Make sure your not missing any orings in your on/off

Well, I double checked anyways but it's definitely not a valve issue of any kind. The problem I'm having with adjusting the trigger is that no matter how long I make the trigger pull, there is a large enough area that when the trigger passes through, the seer starts clicking repeatedly (burst firing).

The battery is back on the charger and when its done I'll give it another go, I was able to minimize the issue so that it would only do a 2 shot burst if I hit the trigger from the side instead of dead on but when I adjust the magnet on the trigger any more than that it's too far in to release.

Check the polarity of the solenoid. If backwards, it can induce a full auto effect. You can check the polarity with a compass. Lay the gun flat on a table. Lay a compass flat on the table at the base of the grip frame. The gun and compass should be oriented so that North is pointed towards the back of the gun. Fire the gun(activate the solenoid) a few times in rapid succession until the compass needle moves and realigns itself. The needle should be aligned so that the South end points towards the solenoid. If the North end points towards the solenoid, the solenoid wires are backwards.

^ Wow that's knowledge and a half right there

Took a bit to tune but it looks like I got it. If the problem pops up again looks like I got a cool new trick to work with. Thanks guys!

On a side note, I was bored today and came up with an idea. I took the trigger off the emag and e-taped a slightly bigger, more powerful magnet to my finger. The theory worked better than I thought it would in function, however, I do want to make sure I'm not messing anything up by doing that before I go play at a field to mess with other players.

I'm using a 12mm x 3mm magnet taped to my finger and just turning the marker on and tapping the sensor to fire it. Could this potentially screw something up?

Someone was testing this very thing last year. Never got any feedback from it. I double sided taped some magnets to my gloves as well and worked ok, just needed to get the timing down and play with the setting and what not. Magnets keeped popping off too.

And no it's not going to mess anything up.

been messing with it all day today and got some very positive results, using electrical tape i wrapped a bigger 12x3 mm magnet around my glove and was having a blast with it, in semi-auto mode im able to reach 15+ with one finger by stroking my finger up and down past the sensor, ill get a vid soon

.... in semi-auto mode im able to reach 15+ with one finger by stroking my finger up and down past the sensor....

That's because it is the same as firing on the pull and release of the trigger. It activates as your finger pulls the magnet down past the HES and then again when your finger pushes the magnet back up to the top. You only need to cycle your finger 8 times per second to achieve 16 bps.

I thought the hall sensor stayed "energized" when the magnet reaches the activation distance and stays in the vicinity. Hmm...Well that blew my theory why mine wasn't working right. I wonder if it was my lvl 10 that was acting up. I was getting a bunch of erratic issues and blamed it on me putting the magnets too close to the sensor.

Once the weather settles down, I'll re-tune that lvl 10 and dig up some parts for this to try out again.

I think that test bed is currently in pieces ATM.

You are correct. It does stay energized when it is within the range of effective magnetism.


fhawkeye mentioned passing the magnet past the HES from top to bottom, which would cause the magnet to put the HES in and then out of the magnet field on the way down and then in and out of the magnetic field on the way back up. The same can happen from side to side. Both operations provide two activations per cycle. For a standard trigger, when you pull the trigger the magnet puts the magnet field close to the HES and it stays there until the trigger goes forward. This only gives one activation per cycle of the magnet.

Mine was doing this until I increased the FIX setting in the Xmod software, what is your FIX setting at?
