ERROR MESSAGE - thread feeder timeout

[turtle]

Hi all, this error message came on one of the XT machines that we've had about for about 5 years.

"Thread feeder timeout trying to find home position"

Ive never seen this error before. Also the machine never stopped and it kept stitching normally.

I couldn't find any info on this in the operators manual or old threads on this board

Should I be concerned?

Thanks,
