E/X-Mag Microcontroller Programming (Atmel AT90S2313)

[LorneCash]

Sort of. Full-auto issue, so I reversed the noid wires.

No Soldering is required but it is recommended if your solenoid is wired backwards. On my 3 X-Mags I get the full auto but either way but one way requires less FIX to solve the problem. Also on my guns I only get the full auto bug in either SEMI or RELS but never both, but I have yet to personally put paint throught my gun with my own software. That's why I need some of you guys in CA and FL to help me out. It's still to cold to play paintball in Milwaukee and I'm just not a fan of indoor play...

I see in the Beta Testers Only thread, folks are running the dwell at 15 milliseconds? Can anyone get their gun operating at the E/XMag's dwell time of 30 ms to prevent bolt and sear wear? Thanks

I think 15ms is probably a good number. Im going to keep a close eye on the bolt and sear just to make sure. I alreay put about 4,000 shots on my Xmag and I didnt notice anything unusual going on with either.

I think that you would know right away if it is too low (I tried it). 30ms will just slow the ROF down noticably.


**edit** - I do see I will have to stock up on bumpers, but for good reasons.

[GoblinGreen]

I have plenty of bumpers to test all day long. How about we play pass the programmer, Big Evil you obviously are finished with yours, chuck it in a box, put on a label and 'mark it' for Africa. When Im finished with it I will send it to rudz

dam im impatient

[dIVEANX]

Ill have mine done before the weekend and will give you some feedback as well

Alright Paul, I have sent my payment in, and I'm registered in the forum, now I'm just waiting.

I have had the dwell up to 25. I am sure that it will fire just fine at 30, but its going to be slower than a lower dwell setting.

The battery will also last MUCH longer with a lower dwell setting.

As far a I have read the 30ms was the entire cycle time for the LVL 7 bolt. I think that's why AGD used that number but in reality you only need to pull the solenoid until the sear is tripped. I've also read that the sear wear comes into play when the sear and on/off pin don't make solid contact, which is why it is very important not to set the ROF faster than the gun can actually shoot or is shooting. As far as I know that is actually where the sear wear comes from, not so much from the lower dwell as long as it doesn't strike again midcycle.

Has anyone tried the blue bumpers?

[BigEvil]

Big Evil you obviously are finished with yours,

Not quite yet Now I have to start buying up Xmags and SFLs so I can catch up to A-Tac-one.

Hahaha sweet! Oh wait, but are there any left?

LOL, I know this guy very well. You'll probably never catch up 'cause I don't think he's done yet.

BigEvil, I appreciate your thoughts but you know that dwell does not affect the E/Xmag the same way it does a pnuematic system. It's been my understanding that it takes about 25ms for the bolt to cycle, regardless (according to Lornecash this applys only to LVL7 [?]). Dwell does not affect how long the bolt stays open but rather how long the solenoid stays open which does affect the sear. So that brings us to the old controversy of bolt wear caused by sear drag. Lornecash says that bolt wear is caused when the sear and on/off pin do not make good contact. I'm sure that I have not seen every bit of information on this that's out there. So, maybe all this past fretting in the over lower dwells is erroneous. If so, that's good news!

I might be wrong about that. I was just trying to remember some stuff I read on other threads. So lets think about this, if you're worried about bolt wear then you should keep your dwell at 25-30. If you want a higher rate of fire you can set your dwell lower but you may have to buy a new bolt every couple years or so depending on how much you play. New bolts are cheap, personally I'd just go with the buy a new bolt option.

I thought Miscue's 4.xx used a lower dwell. Has anyone used that for a long time(over 2yrs)? Do you have any significant bolt wear? Miscue if you wish to comment on this please do.

[11 Bravo]

I dont see a big deal. If you notice any abnormal wear on the bolt or sear- just increase the dwell setting. Its not like its going to destroy anything overnite.
I fired a case thru my Xmag the other day with the dwell at 13. It worked great and I dont see any damage to my sear or bolt.
Also the sear and bolt are going to eventually wear out. They are parts that are designed to wear, arent they? They wear out on mech mags also.

[Mind'sEye]

Guys, to be truthful I ran my Mini-Morlock for a bit at 10 and didn't see any problem either. Then I came across some older threads about low dwell causing the sear drag/bolt wear. When Athomas and BlackVGC posted about keeping dwell higher than 25, I decided to move it up. I don't remember any appreciable loss of ROF when I set it at 25 but maybe the Xmod is just plain faster than the Morlock. I'll use the Xmod when the German's arrive and probably play around with it in the 25 area. You guys can continue the BETA testing of the bolt.
