There was an object placed near the machine, and
the carriage or embroidery frame hit the object
during embroidering.

• Reinsert the fabric in the embroidery frame so
that the excess fabric is away from the arm, and
rotate the pattern 180 degrees.

move freely.
• Place a large thick book or similar object under
the arm head to lightly lift the heavy side and
keep it level.

• If the fabric is hanging off the table during
embroidery, the embroidery unit will not move
freely. Place the fabric so that it does not hang
off the table or hold the fabric to keep it from
dragging.

Fabric is snagged or caught on something.
• Stop the machine and place the fabric so that it
does not get caught or snagged.
