Your machine would be able to perform 5 X 8 embroideries. The hoop size on this machine is recognized by the machine itself, depending of the embroidery file size. So it the embroidery is small, it will indicate that the small hoop is needed.

But U can use the large hoop, position the embroidery where U want then perform another embroidery on the sams hoop.

TRICK : the embroidery size exceeds the hoop? reduce it in X and or Y using this function on the machine
