Dear Alan and Margaret Jannuzzi,
Let's talk rattles for a minute. Here are some of my rattle/noise
experiences from the past.. I'll set this up in list form for easy reading:
Jingle/Tapping sound from lower half of machine while running - oil
rotary hook (Remember to oil at least once a day)
Strange vibration rattle in middle of needle case during color change -
add a little grease to c/c threaded rod behind needle case
Plasticky rattle from top of machine - red plastic covers vibrating
against
white metal casting - shim with wedge of folded cutaway backing.
Hollow vibration when color changing above needle case - "Sea shell
effect"
or vibration between two white covers around thread feed drive motor just
above and behind needle case.
Sticking sound on Y rack motion - add oil to Y rail oil ports.
Raspberry sound when sewing slowly, behind the needle case and sometimes
accompanied with Z axis timeout errors - OIL YOUR RECIPROCATOR!!(2,000,000
stitch timer)
Rattle when toggling the grabber - add grease to grabber cam.
Hard popping sound around bobbin case - bad/damaged bobbin case or
machine
possibly out of time
Vibration/Rattle from mid area of machine - loose hoop arms (Remember
Judy's loose Nuts :)
Tapping sound with every stitch while sewing - back of presser foot
shaft
hitting bent metal grabber piece in Velcro strip area
Clicking sound when color changing (top of machine) - thread feed drive
gear(s) not finding home position after every stitch
Clicking sound when color changing (front of machine) - black front
covers
not aligned correctly
Pounding/tapping sound when sewing thick material - presser foot setting
too low
Metally sounding vibration from back of machine - large white back metal
cover vibrating (older machines) - shim appropriately
Lest we not forget, the infamous "Melco Music" or X, Y, & Z motor
chatter(vibration) while the machine sits idle or starts off slowly - this
is a normal by-product of a far superior servo motor capable of sewing at
incredibly increased speeds with pin-point accuracy. Of course I just tell
myself she's trying to talk to me with a sexy moaning way about her that
I've come to know and love. You can call it what ever you want.
If I think of anything else, I'll be sure to include later. If anyone
else
knows of experiences like this, please let us know.
Ed

Dear List, Just when we are the busiest our Amaya is making a noise that
doesn't sound good. We thought we had it fixed but now after business
hours on Friday we are hearing rattles. Just after Alan said, "we just
passed the 16 million stitch," things have started making strange
noises. About noon we were stitching on fleece and the rattling began
and continued to get so loud that we had to stop everything. We took
the bobbin area apart, the plate off the back, the red side covers off
and the cover behind the bobbin off. Each time we ran a few stitches
and used three different needles at low speeds and it continued. We
removed the thread take-up cam covers and the noise seemed to go away
even at 1500 stitches per minute. Alan indicated that they were loose
so we thought things were fine. Use canned air in some places and
greased the cam with the polymer product in the thread take-up area and
put everything back together. Finished the first blanket and moved to
the next one and now the rattle is back. Alan says it sounds like a
bearing going out in the motor drive area. It sounds the loudest when
it is just starting up and is slow. Can anyone give us a direction to
look? Thank you so much for helping.
