Why can't I attach the SP60417 generic free motion foot?

You can do embroidery or you can do free motion. If you're quilting a quilt sandwich (fabric, batting, backing fabric), you probably want to do free motion quilting. Embroidery would work better on fabric (with a stabilizer) but without the batting and backing fabric.

For free motion, you want a free motion foot--your machine's manufacturer probably provided one in the accessory kit (called a darning foot) or there are many generic free motion feet available for purchase (ie Big Foot quilting foot...). The BIG difference with a darning foot or free motion foot is that the shank is shorter than other presser feet because there needs to extra space between the presser foot and the needle plate so the quilter can easily manipulate the fabric. Usually, free motion quilters will drop the feed dogs to avoid feed dog interference with the fabric's movement, however, some quilters don't drop the feed dogs--just whatever works best for you and your machine. In addition, I use a Supreme Slider on the sewing machine surface--a silicone mat that provides a slick surface to help the fabric move.

There are a lot of web sites and video tutorials on free motion quilting. Take some time to watch them and then practice, practice, practice! It's an acquired skill so the more you practice, the better you will be.

There are most likely some numbers missing from the model number you provided. Usually, there is a 3-digit beginning number, ie 115, 385, 401...

I am unable to find model information based on your number, but you can most likely get a user's manual through Sears or try searching the internet (Make Model manual), ie:

Kenmore Sewing Machine Manuals Instruction and Repair Manuals

Sewing machines generally have two ways to disable feed dogs. One way is a lever or knob on the machine itself that physically "drops" the feed dogs so they are below the needleplate. The feed dogs will continue to operate but since they are below the sewing surface, they will not have an effect on the fabric movement. The other way is an accessory that attaches to the needleplate which covers the feed dogs and creates a flat sewing surface.

Another item that is important for free motion quilting is a darning foot or free motion foot. These presser feet are physically shorter in height than a standard presser foot. This means the darning foot, when lowered, does not apply "pressure" to the fabric when it is lowered. It, instead, provides leeway between the presser foot and the fabric so there is room to manually maneuver the fabric while stitching.

You'll just need to CONFIRM that the presser foot shank is correct for your machine (low shank, high shank, slant shank).

There are probably a multitude of designs available for your machine, either Kenmore or generic brands. Once you've determined your machine's shank, it would be a personal decision as to the design you'd prefer, which could be metal or plastic, closed, open, or clear see-thru as well as various shapes, round, oval, etc. There are also some feet that are spring-loaded so they "hop" while you stitch, or feet that are solid.

These are examples of different darning/free motion presser feet.

Reset main power. perhaps power off by unplugging. If that won't work then find the main operating buttons on the right side and push each one.
You should have a manual on this fairly new machine that will help you.

Yes, your machine takes a low-shank foot. That seems to be the most commonly used type for newer machines.

Yours is a low shank machine, and that is the most common type for newer machines of any manufacturer. eBay and Amazon both offer low-shank darning feet; I recommend the metal one with a metal large circular foot. That's my favorite, and I bought mine for $6.50 including shipping from eBay.

thanks for letting us know

A Curvy isn't an Athena. I have a Curvy and it is a low-shank machine that can use a variety of snap-on feet.

Your machine takes a low-shank foot, and they are very commonly available, either from eBay or Amazon, or any site that sells presser feet.
