Is there a larger foot rest or a way to lower and extend foot rest

Loop and nesting on bottom side is usually a top thread tension or top thread feed issue. Be sure needle isn't barbed at tip. If your machine has a horizontal spool pin, be sure the spool cap is larger than the spool and the thread unwinds from spool per machine instructions.

Test tension of top thread.
With needle up, presser foot up, and tension select = 4, thread machine. Then make a long slow steady pull of top thread. The thread should advance smoothly through needle eye without snagging from top spool. Now lower foot and make another long slow steady pull of thread. Again it should advance smoothly through the needle eye. Note difference no tension (foot up) and selected tension (foot down).


If no difference in foot up/down tension then something wrong with the tension selector or not threaded properly, consult machine manual.


You can do a similar test of bobbin thread tension. Make a slow steady pull of bobbin thread. It should advance smoothly from bobbin with tension similar to top thread with tension =4. If bobbin tension is similar to top thread foot up, then likely bobbin thread has escaped bobbin tension spring... reload bobbin per machine instructions.

Are using embroider table?

Suspect uneven feed of top thread from spool. Check that top thread spool is correct orientation and spool cap is larger than spool.

With presser foot up and needle up, select tension 4 and rethread top thread. Then make a long slow steady pull of top thread. It should advance smoothly through needle eye with even tension (no snagging). Now lower foot and again make long slow steady pull of top thread. It should advance smoothly through needle eye. Note difference in no tension (foot up) and tension select 4 (foot down).

If you are using the appropriate presser foot, you normally shouldn't need to adjust the presser foot pressure. The shaft on a darning foot or free motion quilting foot is shorter so when it is lowered to stitching position, the foot will not rest on the feed dogs or stitch plate. The extra space between the presser foot and the plate allows you to maneuver the fabric. (Be sure to drop the feed dogs so they do not interfere with the fabric's movement. Or, if the feed dogs do not drop on your machine, you should have a special plate in your accessory kit that covers the feed dogs.)

Most free motion feet attach like the other feet.

It is creating "thread nesting" also called birdnesting. Could be several things:
1) make sure before you thread the upper thread, RAISE the presser foot so the thread will seat properly in the tension disks
2) drop your feed dogs before you begin to free motion
3) your free motion quilt foot, when lowered, should not rest on the fabric. (Be sure you are lowering your presser foot when you want to stitch!) You should be able to move the quilt sandwich easily under the presser foot. If the foot applies any pressure to the fabric, you may need to release the presser foot pressure (consult your manual). Or you are using the incorrect presser foot for your machine.
4) If none of the above, you need to tighten the upper tension AND
try this method before beginning to free motion stitch:

How and Why to Bring up the Bobbin Thread

...

Sometimes the feet are faulty, rest the snap on foot on the plate and lower the shank down and press hard

Put the tension back to the normal setting - around 4.

Lengthen the stitch to accommodate the multi layers.

When you are sewing and come to a thicker section, stop with the needle down, lift the presser foot and place a folded scrap of fabric under the back of the foot to keep it even. Lower the presser foot and continue sewing.

Attach the foot to the machine, making sure you have the large hook over your needle bar. move the selection to the number you want to gather.... 1 is a small pleat gather, higher numbers are larger. the fabric is placed so that it goes over the bar underneath, then over the rest until under the sewing area. Try a sample first to see how it works. It really does make a nice ruffle.

Your machine should have a special buttonhole foot which has a place to insert a button, You will probably have to pull on opposite ends of the foot to open it. Place the button in the foot and then squeeze it together to make the button secure. Attach the foot to the machine. It should snap on.
looking at the left side of the machine you will see your needle bar at the front and the presser foot bar at the back. You should also see another lever which needs to be pulled down so that it rests in the buttonhole foot.Select buttonhole on your machine and it should sew. The button determines how long the buttonhole is.

The 1600-DB requires a special Walking or Even Feed Foot due to the high sewing speed, so ensure that you have the correct foot, as the "normal" top loading machine foot will not fit.

I hope these images will assist in showing how the fitting should look.


This is the Normal - WRONG - foot to compare:






This is the CORRECT Foot:






From the Janome Accessories Guide:


"The even feed foot walks over fabric to assist with smooth feeding. Fabric can be sewn without puckering as the fabric is gripped and fed by both the upper and lower feed dogs. This foot has been specially designed for durability and to work at the high speeds of the 1600 series.
