Sewing trouble after a timeout error

[bluefoxprints]

Hello,

I am hoping to find some help about a problem with one of our two machines, which are both Amaya XTs.

Last week, at the end of a sewout, I returned to the machine to change the items out, and I noticed an error on the screen. I wish I could remember exactly what it said, but it was something about a timeout error on return to origin. Thread in needle 4 (the color it was sewing) was broken. I closed the error window and cycled the machine on and off.

When the machine came back online, I went to re-thread needle 4, and I saw that the thread from needle 3 had pulled loose from the needle during the sewout and had gotten jammed in the workings of needle 4. This has not happened in the many years we've had these machines. The thread was jammed somewhere in the space under the take-up lever, toward the top of the groove in the plastic cover. I worked it loose and put another item on to sew, but the machine will not now sew. It goes about 10 stitches or so, and then the thread breaks off clean. Sometimes, as it starts to sew, it seems as though the bobbin is not catching, and sometimes, it seems the bobbin is catching and then the thread breaks. When I take the work out of the machine, the bobbin thread is sometimes hanging out of the case in a loop. I have tried sewing on a different needle than the one that caused the error.

My manager is extremely good with machines, and he's looked in there for jams and anything wrong. The only thing we've been able to find is that the bobbin assembly didn't look right when we compared it with the other machine. There is a pointy piece on top of the assembly, and it was a little to the left compared to the other machine. He fixed that, but the machine is still not sewing correctly. It is also making a metallic grating noise when it does try to sew.

If anybody has any ideas about where we can look to solve the problem, they would sure be welcome. Our shop is in a fairly remote area on an island, and the nearest tech is quite far away.

Thanks,

What specific area of the "workings" of needle 4?

Can you , after depressing the E-Stop, rotate the Z-axis shaft by hand a "FULL" 360 degrees on the problem needles? If not, this may indicate that thread, fuzz, lint, etc, may have worked its way up into the needlebar bushing(s)...

I am assuming that you are referring to "Hook Timing". I think the "little pointy piece" you are describing would be the point of the rotary hook. You said your Manager "fixed" this to look like your other machine.... How did he go about "fixing" this? There is a specific procedure when adjusting the hook timing....

Did you take out the "threadfeed rollers and specifically check down in the pockets to see if thread was wrapped around any of the threadfeed gears?

The metalic grating nowise? Where is this iminating from? Is it a constant grinding? If it is coming from the rotary hook/bobbincase area, it may mean the needle guard gap was not set properly when the rotary hook was adjusted to look like the other machine. Did your mManager also reset the retaining support finger gap after adjusting the hook timing?

Need a lot more specific information about what is going on in this case..

This hasn't happened to me, but you two are the greatest for monitoring this group and staying on top of everyone's problems. Thanks for being here.

I And I second that statement!!

Thank you for your suggestions. They didn't lead us to the problem, so we made a call to Melco. The problem was solved that way. There was a gear that we'd never accessed before that had all of the thread wrapped around it, and we're all golden now.
