Hey everyone,
 
As a point of reference a large portion of my products are T-shirts, sweat
shirts and polo's, light and heavy weight.  When I was doing embroidery
using a home embroidery system many years ago I found the key to embroidery
on these thinner materials was to use a tear away sticky backing to secure
the fabric to the hoop after the fabric is hooped without any backing.  The
same technique works great for the AMAYA as well.  The only drawback is the
increased level of cleaning required to remove the residual adhesive that
gets into the needles, bobbin, rotary hook and trimmer assemblies.  I
probably clean these areas every three to four weeks using WD-40 and Cotton
Tipped Applicators and in my case it is worth the effort.  These parts get a
regular inspection, cleaning and lubrication as a result.

I just hope that was the problem and she continues to run well. I have been
using allot of spray adhesive lately, mostly for t-shirt material so maybe I
should clean more often, next time I think I will try the WD40 trick. I am
too tired to continue tonight, I will start again in the morning. If I have
anymore problems you will be hearing from me.
 
Thanks again
Russell

Russell,
    First of all, hats off to you reinstalling your rotary hook.  As far as
numbers go, not too many people can do that correctly.
But sure, a dirty rotary hook can cause the thread to not slip through it's
proper channels like it's supposed to - giving problems along the way.
Theoretically, you want your machine to look and run like it was when it was
brand new.  And they certainly didn't sell you a machine with a dirty rotary
hook.  Now that's not to say one can't run for years without cleaning their
rotary hook and not experience problems.  It all depends on what kind of
sewing you do and things like whether or not you're using spray adhesives
and such.  People who sew on hats most of the time may choose to clean their
RH's more than others because of the buckram fallout.
    Now you may have had nothing more than an adjustment problem.  It is
possible for the rotary hook's setting to slip.  Not common but possible.
(Three screws biting on a round shaft)  And maybe just you taking it off and
putting it back on and setting it would have done the trick.  Or possibly a
combination of the two.  Only Queen Amaya knows and she ain't talkin'.  Oh
well, as long as she' singing...
    Glad you're running better.
Ed

To All Techs,
 
    I tried several different thing to try to fix my thread fraying/breaking
problem and nothing seemed to work so I decided to take the rotary hook out
to inspect it for nicks and scratches and found it to be ok but what I did
notice was it was very dirty from spray adhesive and lint, so I took it
outside and cleaned it with degreaser reinstalled it and now it seems to
work allot better. I will try some more designs tomorrow to make sure it is
ok. Could the rotary hook being dirty cause all the problems I have been
having?
 
Thank you for all the help, you guys are great
Russell

Russell,
    That could be a problem.  When you ask it to give you a material
thickness of 3, you don't want to end up with a 2 or a 1 because the spool
won't let go of the thread.  You should also know that you are experiencing
thread frays.  Could also be caused by a bent needle, too much rotation on
your needle, a scratch somewhere along the threads path under the needle
plate, presser foot up too high, etc...  
    If your thread is dancing around too much, you should consider cleaning
your rollers, both red and yellow, and cleaning your bobbin case.  Sounds
like you're not getting the tension you're supposed to have.
    Does this happen on all needles or just one?
Ed

Hi Ed,
 
    I did grease both the red and yellow rollers when I installed them. When
the machine is running I have been watching the tread come out of the
rollers and it does stay centered, when I do get a thread break it seems to
only break half of the thread and sews for a few more stitches (30 to 50)
then completely breaks, I only here the pop when the first part of the
thread breaks, the other thing that happens after the thread breaks and I go
to fix it is the thread seems to be hanging up on the thread spool. I have
checked the thread path and everything is fine it just comes off the spool
with tension at times, some days worse then others. I put a humidifier in
the room with my machines hoping a constant humidity level will help.

Russell,
    It has been my experience where when someone upgrades to the new
rollers, they tend to do the change over -forgetting the importance of one
step.  The lubrication step.  Or maybe they only do half of this step.
Meaning.....
 
Most folks are, in fact, putting a spot of polymer grease on the hubs of the
new yellow rollers but they are forgetting to put a spot of polymer grease
on the black shaft where the new red rollers are installed.  You have to
understand that this is plastic on plastic with a good bit of tension
between the two on the underside of the shaft.  There is what's called a
"load" (or pressure) placed on this roller and shaft stemming from the
pressure between the red and yellow rollers.  If one installs these red
rollers dry, then what happens next is the red roller isn't allowed to spin
smoothly and, in effect, hangs up as it's trying to spin.  When it hangs up
or stops sporadically, usually for a micro second,
(spin-spin-stop-spin-stop-spin-spin-spin-stop-spin-etc... if you get my
drift) the thread is then forced out to the side of the two rollers.
Usually this is to the left side (has to do with angles and pressures).
 
Now that the thread is not pinched as it should, between the two rollers,
and is free to come and go, the next stitch happens sort of like this.  The
needle pushes the thread down thru the needle plate where is hands it off to
the rotary hook.  The RH takes is around the park one time where now the
take up lever takes control and brings up the excess thread back up and out
from under the needle plate area.  This can only happen if the thread feed
rollers are doing their job in holding the thread in one place.  It's kind
of like trying to catch a fish without reeling in the line.  It will never
happen and you'll eventually lose the fish when you run out of line on the
reel.  But in our case, the excess thread now gets tangled in and around the
rotary hook and resulting in what looks like a birds nest under the needle
plate and then a loud pop or snapping sound is next as the thread eventually
breaks violently.
 
When ever you get a thread break, you should inspect the thread path which
includes checking under the thread feed rollers. You might just find that
the thread is, in fact, not centered between the two rollers.
 
In summary, put a little dab of polymer grease on the red roller shaft
making sure not to put so much where excess spills over both out and on the
rolling surface of the roller(s).  Also clean off the shaft first with a
tissue being sure to remove any old nasty residue that is still on the
shaft.  Doesn't matter what anybody says, residue ain't as slippery as new
fresh grease.
 
Keep in mind that at the factory, someone did this originally and the old
red rollers you removed probably has some residual grease still on them.
But the new rollers you're installing are bone dry.
 
Sure hope this solves your problem.

Subject: [amayausers] Upgraded Feed Rollers, Lots of thread breaks
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
