Hi All,

In 2 months 1 Amaya has a demonstrated a nasty habit of breaking a thread, then 
displacing the next stiches (has done so 3 times).  Once the thread breaks, the 
machine moves about 0.2" down in the Y-Axis.  If you do not catch it 
immediately, you ruin a garmet.

There is a particular "sound/sequence" the machine makes during the thread 
break which may indicate the machine is going to move uncommanded.  Let me try 
to describe the sound:
1.  Normal sewing sound
2.  Small hangup and 'slap' of thread results in a small ball of thread on top 
of the stiching (almost like it "shoots" a ball of thread through the needle
2.a - may shred thread at this point.
3.  Sewing sound gets rougher
4.  Slightly louder 'slap' and then break/shred. 

Is this what happens if the thread get caught on the rotary hook?  
Thanks,
Jim
