    Russel,
    Yes, humidity can play a role. Cones of thread can vary widely in how they 
unwind. Some are very loose and just fall off the spool while others appear to 
have the thread constantly being pulled up the length of the spool. I have had 
numerous issues with thread hanging up on the very bottom of the wrap. It seems 
to pull tight into the bottom of the cone and the thread. This is more apparent 
on new, full cones of thread. Lately, if I find a cone of thread, that is 
hanging up as you have described, resistant, I pull off several feet of the 
thread and discard it. This seems to work most of the time. I also find that 
the cones with the most resistant are or appear to be tightly wound and these 
also tend to "twist" the thread. Pull several inches of thread off a tighly 
wound spool and trim it close to the needle and watch it unwind, then do the 
same with one that is loosely wound and quite often there is a noticeable 
difference......

    For some that may think, well, lubricate the thread with something like 
"Stitch Ease", to get it to feed smoother.......not a good idea as you do not 
want lubrication of any kind to get on the thread roller assembly and cause 
slippage between the rollers and the thread.

    Hi Rod,

        I think the design may have gotten corrupted when it was sent to the 
Amaya, I just did the Ampass test and had 4 thread breaks, one was on the small 
lettering at the bottom and the other three were on the last color of the horse 
and carriage, with all 4 thread breaks when I lifted the pinch roller to pull 
more thread out there was resistance, the tread wasn't coming of the cone 
smoothly, do you think humidity could cause the thread to not come off the cone 
smoothly? Most of my thread breaks in the past seemed to have the same problem. 
I talked to Hugo on the phone earlier and he asked all the questions you asked, 
that's what led me to do the Ampass test, the color that I had all the thread 
breaks with yesterday worked fine.

    I am going to buy a humidifier to see if that helps.

    Russell

        Hi Russell,

        Have you discovered just what the problem is? To start having problems 
just because the rollers were changed out would be unusual. When replacing the 
entire kit, did that include replacing the red pinch rollers AND the black 
plastic covers? Just have to be sure on this......the holes in the new plastic 
covers are larger than the older style and the pinch rollers are knurled on the 
surface. I need to ask some questions......it is very difficult to diagnose a 
thread break problem without going through a process of elimination not knowing 
what you have already done. Some of these questions may seem unnecessary but 
have to be asked to gain a data base of info on my end.

        I have not witnessed the overall increase in MT as is described in the 
instructions..only on some things....still need more experience with this.

        Is the thread sticking to and being sucked around the new rollers? This 
definitely causes a "pop" when this happens and the thread breaks.

        Were the rollers squeaky clean with no oil or grease on the surfaces to 
pick up the thread?

        IS "force download" turned on? If not, turn it on. Your design may have 
become corrupted in the RSA and CSA download to the Amaya. We must eliminate 
the design as a potential "cause" regardless of how many times it has sewn out 
perfectly in the past. What is the design? Is lettering involved? Short 
stitches off or on? How big is the design......small? Jacket back?

        Is your presser foot set correctly?

        Have you tried to sew the "Ampass" test design? When you run this 
design, use two pieces of medium to heavy backing, MT of 3, 1200 stitches per 
minute and your presser foot properly set.

         Are your needles set straight ahead or 5 degrees to the right....never 
to the left? 

        Is the thread breaking happening on all needles? Or certain colors of 
thread? New thread, old thread? 

        How about needle depth...the newest speck is to have 3/8" plus or minus 
1/8" of the eye of the needle showing in the bobbin case area at bottom center 
position.

        Poly or rayon thread?

        Did you grease the center bearing post of the red pinch rollers? Did 
you grease the center brass bearing surfaces on the new rollers?

        How tight is your bobbin tension set? 

        What needles are you using? Size, brand, titanium, standard?

        Have you thoroughly cleaned out the bobbin case area?

        Have you been using sticky spray or were you using sticky back backing 
with fast frames?

        What backing and what material are we talking about? 

        Hooping tight/taut?

        Thread spindles at the proper height?

        Humidity. Has it changed or about the same? Is the thread untwisting on 
the trimmed ends? How about the break, is the end of the thread badly frayed, 
untwisted, or is it a clean break?

        Have you, or do you know how to do a "Thread feed 200" check to see if 
the thread is being fed at the correct amount by the computer?

        Is your needle plate centered? Have you carefully checked the hole in 
the needle plate for needle strikes and/or burrs?

        Have you checked the face of the retaining support finger for the hook 
to see if there is a scratch/gouge/burr on it?

        Have you looked (magnifying glass) at the face/surface of the hook for 
any scratches, burrs, damage from any broken needle etc?

        This is just a start of the questions that run through my mind when 
someone says "thread break." All things being equal, and the only thing to have 
changed is roller replacement, and given the fact that you did not mention any 
problems before this replacement, one must first go back to the installation of 
the "kit" and lubrication of the rollers. This is the place to start and then 
we will go from there.

          Hi All,

              I just upgraded to the new yellow thread feed rollers and now I 
am getting allot of thread breaks, the directions said to go up on the MT but 
when I do the thread dances around too much in front of the name plate, the 
design I was design I was working on is normally set at 4, I have tried going 
all the way down to 2 and had the same problem. When the thread breaks there is 
usually a popping sound, I checked the hook timing but that seems to be ok, 
also new needles. Does anyone have any ideas of what might be going on?

          Thanks in advance
