OK so if have 2 different issues, barrel breaks and chops

Let’s deal with each one separately.



Barrel breaks are due to poor ball to barrel match or are due to poor quality misshapen paint so I would look at these areas in regards to any barrel breaks that you are getting.

In very basic terms all paint guns do is provide a blast of gas that blows the ball along, once this blast of gas has been applied to the ball and the ball is moving down the barrel the gun has nothing to do with what happens to the ball, so anything that happens to the ball from then on is due to the ball itself and the barrel. The normal cause for barrel breaks is friction between the ball and the barrel being too great and this stresses the ball and causes it to break.

Note there is a difference between good fragile paint that may look like this but be fragile O, and poor quality paint that may be out of shape 0.

A good test to eliminate the barrel from any equation is to remove the barrel and then proceed to shoot the gun, this will show you if the barrel is responsible for any of the breaks.



Chopping

What do you term by chopping?. To me a chop is when the bolt Physically cuts the ball as it moves in on the forward stroke, is this what is happening?

If it is then the first thing that I would look at is the loader speed /paint type setting and the eyes. I would run a gun with older software on a loader speed of 6 to 8 (in cold weather) and a newer version gun I would run with a paint type of 4 to 6. I would also carry out an eye test to make sure that the eye is working correctly. The eyes will only permit the marker to fire once the beam has been broken by a ball heading into the marker, this in itself pretty much eliminates chopping if it is working correctly and the loader speed and paint type are set as mentioned above.



Other things to look at.

Make sure that the ADB fingers are good and are not showing signs of damage or wear. If in doubt swap them out.

I would also run with the 0.695 barrel when its cold or if paint is bad as this also helps to reduce barrel breaks, so you may want to move to the 695 barrel

Check the pressures again, set the in line reg (exhaust valve side) first and set that to 270 before you move on to the LPR.

Dwell should not need to be changed from its normal level


Can a mod sticky this please?

cool thanks man...

wait a second, i have a ques. about the paint type on v2.1 software.

wouldnt it go like if u set it to like fragile 1, the most fragile, then it would go easy and not stress on the ball, so wouldnt u always want it in the fragile area so that you would never put to much force on the ball and never chop??

help

and also, i was going to go set my lpr, but i didnt set my mini reg output yet.

is it bad if i only set the lpr? or do i have to set the mini reg output first?

Set the minireg first to 270 and then proceed to the lpr

We will update the cold weather thread with the A1 hopper speeds from the other forums that we already posted a sticky and add here.

The paint type is what used to be known as hopper speed. The lower the setting the longer the pause between when the ball is detected and the marker can fire. The lower setting is easier on paint but it then can slow down your rate of fire. That is the payoff.

Yes it lowers your rate of fire which helps you to shoot fragile paint without cliping and chop.Angel ones does not clip much like the older generations becuse of its ramped bolt.Shooting fragile paint has a cost:)

how do you guys set the mini reg?

set the in-line reg out-put to 270psi using the exhaust valve pressure gauge Adjust pressure output up or down using the velocity adjuster screw until an output of 270psi is indicated on the gauge(---Shoot 3 shots after each adjust turns in order to stabilize the new pressure--)---.Thats how I do it---.After the in line proceed to the lpr.

Bob,I couldnt find where it got stickied?
