Data from official source
The N 3300 Pro is a computerised machine with 120 stitch programs in total: 30 utility and 90 decorative, selected with buttons and a monochrome LCD display. The hook is a horizontal double-rotary type, and the buttonhole is automatic, one-step, with 6 variants; the needle threader is automatic. Presser foot pressure is adjustable, and the machine sews with a twin needle.
Besides the foot pedal, it starts with a start/stop button, speed is set on a continuous slider, and there is a button for stitch-by-stitch sewing at minimum speed. The feed dog drops for free-motion quilting, across 7 segments. Top speed in the technical table is 860 stitches per minute, the motor draws 55 W, and the machine weighs 7.52 kg. It can be upgraded into an embroidery machine with the matching EU7 unit.
The walking foot stays a separate accessory, not included, and the thread is still cut by hand: being computerised did not add an automatic cutter. Thread tension also stays manual, to be adjusted every time the fabric changes.
