mini still breaking paint

[leslielam]

hiya, our mini just came back from paintball solutions, it went to them because it was breaking paint right out of the box, (supp. the spring) and was blowing it back into the hopper. Before we sent it in we came here and read the stickies and followed the proper break-in procedure that was established. The gun was still chopping paint like mad and blowing it back into the hopper. The entire inside of the gun was a mess. The little white check valve was in place and everything was at the factory specs. They replaced both boards and said the gun shoots great. It was supposed to have the new board in it already. Okay here goes, the gun shoots great on semi, I put it on setting 3 (full auto/nxl) and its smashing paint like crazy, just like it did before we sent it in. It filled the hopper neck with paint (vlocity jr w/gangstar chip). We are seriously thinking of sending the gun back :( .
We have used 2 different hoppers, halo b w/chip and the vlocity jr w/gangstar. Both work great with our other guns. We have tried different paint, all fresh. New batteries, checked the eyes and the detents for cleanliness. I raised the bip to 6 and the rst of the settings our stock.
WE NEED SOME ADVISE THIS IS BAD THE GUN JUST CAME BACK AND STILL ISN'T RIGHT:pissed: .
THANKS

make sure the oring on your poppit is in good shape and try a better lube on it. make sure it can move with out getting hung up. The poppit staying open too long is what causes blowback unless the return spring on the bolt is still not broken in. Another thing that can cause your poppit to stay open too long is too high of dwell. Make sure you can pass the 2 ball blow back test. Lower your dwell until you can. Slightly strech your detent springs and lube the detents themselves. When you reinstall them, make sure they can move and do not stick. Dont use a higher mode on your loader than you have to in order to get the bps you want to achieve.

Although some people have fixed chopping issues by upping the bip setting, I feel that anything over stock 1 bip is putting a bandaide on it and taking the easy rout on tuning. I can use a gravity feed loader and set it on nxl 20 bps and shake the whole loader empty with out chops.

I use lurker lube and have shot 2x more $ worth of paint through mini than its cost. (uggh no wonder I cant save $) but my gun keeps getting better day by day as I use it and it breaks in more and more. The more you let it cycle, the better it will get.

I tried firing the gun without the hopper, with 2-3 balls in it, I put my hand over the feedneck and the upper ball was slapping my hand pretty hard. I use shocker lube (sleek), I'll pull the gun apart again and try lubing everything (again) lol. Shouldn't they have noticed this when I sent it back to Paintball Solutions? Sorry but is there a specific test that your talking about to test the 2 ball theory (tissue test)? Ill also run another tank or 2 thru it.
Thanks

I ran 5 tanks thru it on full auto, checked your numbers with the book, the default dwell setting in the manual says that it is 38, where I had set it!!! per the manual, yes 38!!!! Now when the gun came back and it was breaking paint I checked all the settings and it was set at 28, BIP 1, so according the the manual I set the dwell to the default.:confused:
I saw were you said were going to lower yours to 26 (weather), so after the 5 tanks, I took the bolt out and checked everything over, poppet looked great cleaned everything relubed with the sl33k. Set the dwell at 28, the bip at 20. I remember seeing that the spring new took quite a bit of force to collapse it, I can squeeze it together with my thumb and forefinger now.
I refilled the tank from our well used friendly scuba tank, filled the vlocity jr and went out. I shot the whole hopper on full auto and it didn't break a ball. I hoping we got it fixed. I tried another hopper with the bip lowered to 10 amd its shredding paint. gonna take it back to 20 and try again.
It looks like maybe there's a misprint in the manual for the dwell?
Thanks tons for the info.

ADDED, reset the BIP to 20, broke 1 ball about half way thru the hopper, stopped, cleaned barrel finished off the hopper

ADDED again (I'm dreadfully Sorry about this) Contacted Paintball Solutions advised them what was going on "again/still". Told them my settings, they said they were ok. BUT: I was told by the tech that the R&D guys had recently found a problem, within the last couple of weeks. The initial run, some of poppets are at fault. The old one's rear seal is defective, not all, just some of them. He said they (the old ones) will look alright, so a person like me wouldn't even know it. He said this is the fix to all our gun's problems. They just got the new poppets in and he is mailing one to me. They didn't have the new poppets there when my gun left on Friday 06th, I will update, when I receive the new poppet and give it a try.
thanks again

the manual where it says 38 is stock is a typo. 28 is default. Do a reset on the board and you will see that 28 actually is default.

My gun is having the same problem, it breaks paint if i shoot fast with it, the grip also ripped and the foregrip is ripping off.

[leslielam]

:pissed: Well, just an update we still haven't received the new poppet, I've talked to tech support on 4 different occasions with the promise that it's on it's way. The gun is sitting in it's case unused, a $400 boat anchor is all it's worth to us. They seemed to really be helpful on the phone, but nothing has happened:(

[spydyrodeo]

Have you tried cleaning the poppet hole out?

[leslielam]

It's clean, paintball solutions is telling me ther was a manufacturing flaw with my poppet

[spydyrodeo]

Oh.

Guys, I know your frustreted and you shouldn't have to deal with issues like this on a new item, but if you can hang on through it you will be very happy with the results. Mine works great out of the box. Unfortunatly the company and gun is getting a bad rap due to all of the mfg'ing issues that are usually standard on a new gun that is completly a new design.

Stick it out and when your gun works great in the future, I would encourage you to repost.

[leslielam]

well, we got the new poppet and now the noid is bad it wouldn't cycle at all with or without air, I called and the tech had me take it apart and he advised me that it was bad, so the gun is back at paintball solutions, someday, someday, I'll keep tapping my ruby slippers:rolleyes:

[floydhead]

i think this guy is doing advertisement to pmr or etek ego....:eyes: :eyes:
my mini is working perfectly fine out of box...

[leslielam]

:rolleyes:
Floyd, nope I'm not a marketerer or anything like that, just a consumer who has a faulty marker. If you read my review and posts I have never, ever, ever mentioned another marker model. We just got back from a tourny in New Jersey and there where minis there that worked flawlessly, I just got mine back today, they replaced the noid, replaced a defective body??, cleaned and greased, set BIP to 3 milis and test fired it.
It is still has unbelievable blow back, put 2 balls in the neck and the second ball goes literally 10 ft in the air, I fired it on the porch and the top ball broke on the ceiling :crazy: If you have a suggestion to help me I would greatly appreciate it. It also has the new poppet in it. Hers an offer, I would be happy to sell it to anyone for $325.00 plus shipping.

Just out of curiosity, what is your dwell set at?
And...in relation to bottomed out, how many turns out is your velocity adjuster?

[4x4le]

Hey chuck! Cool to see you here too! I too am curious to your settings and vlosity adjuster. I CAN get mine to have blow back if I try. Here is where you want your velostiy adjuster.... make it flush. screw it in 2 full screws (and take note of where it is). Now screw it in all the way. Now screw it out full screws. Dont have it in any more than where it is now, and dont have it out any more than it was when you screwed it in. Try lubing your poppit as they might have done a bad job. Dryfire it some after you lube the poppit to get it sliding right. Adjust the input pressure to get you close to the desired velosity and use a dwell of 28. Also, go ahead and screw that 3ms bip. Go back to 1 ms.

edit: and I know you shouldnt HAVE to but an aftermarket product to rid it of blowback, but the rhythem innovations bolt truely does rid minis of blowback. You know how I said I can make my mini have blowback up there?? Well, I tested the derlin bolt that way. I used the stock bolt and tuned it to HAVE blowback, then I took that bolt out and put in the derlin one while keeping all of the settings the same and guess what? The second ball didnt even jump like it does sometimes with a well tuned mini with the stock bolt. I took my shot with the 2 ball test and I thought it flew out of there so fast I didnt even see it, but I looked in the breach, and there it was sitting.

[leslielam]

Thanks guys for the feedback:)
Here the settings on the gun, back from the techs
setting 1) Firing mode - Ramping/PSP - 15 bps
2) ROF - 15
3) Dwell - 34
4) BIP - 3
5) Ramping point - 3

Now on the velocity adjuster it was 1 1/4 turns from the bottom (clockwise)
from flush to bottom i get 3 complete turns, so that is kinda hard for me to get 2 full turns from flush and 2 full turns from bottoming out position, I'm going to try the adjuster at 1 1/2 from bottom and give it a shot after i relube and run a couple tanks of air thru it. I also adjusted the bip and dwell
Thank you again, I'll repost after the test.

[leslielam]

I started with the adjuster at 1/1/2 from bottom and did the 2 ball test, ( I had relubed the poppet and ran 2 tanks of air thru it), no blowback!!!!!! :goody: the 2nd ball kinda jiggled around a little but it made no attempt to leave the atmosphere. I did this about 10 times, all good, I then turned the adjuster in 1/4 turn, (visual ball velocity appeared a lil slow) and tried it again, same results a little wiggling but no jumping out of the neck.
I then took a full hopper and ran it thru on the ramping/psp NO BREAKS:) . I ran a second hopper thru and again no breaks:D

Must be that the new poppet wasn't possibly broke in??? The adjustments weren't all that out of whack (maybe I'm wrong)
Thank you again for all the advise, I'll give it another shot tomorrow to reassure myself lol.
KUDOS TO YOU GUYS

[Mr Virus]

I hope that this does the trick for you.
Im finding out that minimizing the poppet travel, by turning out the velocity adjuster NO MORE than 2 turns...and compensating with a higher dwell rate, equals better performance overall.

Keep us advised!

[floydhead]

oh sorry... it was just a little suspicious.... but well .. my mini has always work alright nut my brothers mini... it choped and chopped.. but this was very easily corrected by dryfiring and lubing a litle... try it... hope it works..
