First, we need to determine if the issue is happening with ALL needles or just one or a couple. If it's only happening with a few needles, it's possible that the issue could be related to the Thread Path or Tension.
Please make sure that one of the Thread Break Sensor Wheels is spinning while the machine is functioning.
If the sensor is Spinning and the Thread Path looks correct, we'll need to check the sensor on the back of the head.
To do this, set the machine to Needle 14 and remove the cover.
Do not touch the wheels or sensor, as they can be easily damaged. Try cleaning them with Compressed Air to remove any dust or debris that may have accumulated.
If the machine is still stopping, we'll need to adjust the sensor settings for further testing:
Go to "Parameter".
Select "W_Param".
Select "T.B." from the top row.
Once in the "T.B." menu, confirm that the settings match the image below.
If the machine continues to stop, and all other areas are correct, then it's possible the sensor may be faulty and might need to be replaced. Please let us know if this is the case.
