Bobbin sensor???

[debndukes]

I assume there is but where is the bobbin break sensor on this thing??? [img]redface.gif[/img] ) (XT). False thread breaks every 10 stitches if its on, and if its turned off, well then, you know how that works. I cleaned the cutter / casing and double checked the bobbin tension. Can it be adjusted to be "less sensitive"?

Check you column & fill thread feeds- try lessening them.

The bobbin and top thread sensor is a combination of that long narrow silver tube in front of the needle case that is held in place by two red plastic ends and an internal mic or mics (don't remember if Brad told me if it was one mic or more) that each top thread wraps under and back up to the take up levers.

Brad told me that the Amaya OS monitors the snaps/clicks that is made by the thread as it hits or slaps against the the silver tube when the take up levers feed the thread. Apparently the top thread clicks sound different when the top thread is broken than when the bobbin thread is. Can you imagine how fast the Amaya OS and the Amaya CPU is able to monitor these clicks/snaps at 1,500 spm? So technical and scientific! It never ceases to amaze me how advanced the Amaya and OS are and how smart those folks were who developed them.

I had the privilege to talk to one of them over a year ago....you know who you are....you are always in my mind when I use the Amaya OS that you developed for us. I never forgot that 2-hour conversation and I think of you and the conversation we had often. Thank you very much!

Being an IT specialist in my real job, it is always helpful for me to know these things so I can learn to work "with" it. I am still learning though. I'd just like to take the Tech class so I could understand more! There was so much that we did not learn my 2-day Amaya XT training. We learned "how" but not "why". I was memorized with all the information that Brad shared with me when he retimed my Amaya XT last month. I'm sure there is a whole bunch more that I could have learned from him.

Your explanation is very close to what is going on.
Hoever there is noting to do with "Sound" It is everything to do with vibration and the tough ? tension force on the silver sensor bar.
In tech training they showed us the electonic display the machine sees. alot like an EEG of a very active mind.
and in that they can see where the thread interaction with the sensor is normally and when it is there with or without the interaction of the bobbin thread and when top thread is broken.
It is also so sensitive that it can adjust the thread feed to keep the stitches perfect on the fly.
It is all part of auto actifeed.
