About Me

My Photo
Sewing and cooking are two of my favorite things. In the past, I often found myself searching for pictures and details of projects I have done, without success. So I decided to start documenting my creations. Then my son suggested I add my recipes to the blog so that they are documented also.

Free Motion Quilting on the Pfaff Quilt Expression 4.0

Well I have had my Pfaff Quilt Expression 4.0 for about 6 weeks now and finally am comfortable with free motion quilting with the Sensormatic foot.  Originally, I thought I would use the spring free motion foot but actually like this little Sensormatic foot.  I had great difficulty at first and I am not happy there is so little instruction in the manual.  I have searched the web and sewing forums and as usual have found several places with comments and recommendations.  I found that the Pfaff Quilters Forum  http://www.pfafftalk.com/chatroom/mvnforum/index was most helpful on this topic. I took advice from these sources and here is what works for me.


Sensormatic free motion foot

I had trouble putting on the foot at first.  As shown below the top plastic hooky thing goes in front of the needle bar.

 Feed Dogs:
Lower the feed dogs by pushing the feed dog lever on the front of the machine to the left.


Under the Settings Menu (the button with the tool icon) I turn on the Sensormatic Free motion.  I change the Pivot Height to -3 and I turn off the Auto foot lift. This will automatically change the thread tension to 5.2 but on my machine I need to increase it to 5.4 or 5.6 depending on the thread that I am using. This will also automatically set the stitch length to 0.0.


I have experimented with embroidery thread, King Tut Quilting Thread and Coats and Clark All Purpose thread.  All have worked well as long as I have the same thread in the top and bobbin. 


I am using a 90/14 Organ needle; I had been using a 75/11 and experienced thread shredding and since changing to the 90/14, all is well.

So now I am quite happy with FMQ on my QE4!!


  1. I love that you shared your settings and pics here. I also have this machine but have been having some looping problems on the bottom underside of my FMQ work. I think I have too much top thread coming down to the bottom and looping loosley there. I don't know how to change the top tension (because it is so automated on this machine and also I want to avoid breaking top threads. I will try a few of your other suggestions. I totally agree that there is not much out there for videos and manual help or even blog help for this machine. AEven the Pfaff website does NOT have an english translation button! LOL Hello! Please keep sharing your progress and projects. Kathy Aho

  2. Rockester, I have found that if I use the spring motion foot I have no tension issues. You can change the top thread tension by selecting the tool icon and the tension setting will be the top item. A Pfaff educator told me there are less tension problems with the spring foot because it actually holds the fabric down when the stitch is being made.

    1. Hi there. I am a newer sewer, and am trying to find the difference between the spring foot free motion and the sensormatic free motion...I have the foot shown above but also have the open toe free motion foot...I tried to use the spring foot and have the machine set to do it but all it did was skip stitches, and (I) made very uneven stitches...

    2. How do I use the spring one correctly, should I even bother? I do get decent results with sensormatic...

  3. The pivot height at -3 worked for me too. I had the 4.0 and I upgraded my machine after a year with a great dealer trade-in program, to the 5.0 and never have to readjust the pivot height. I am surprised that Pfaff, a quality company, would have produced a "quilting" machine that requires adjusting of the presets for free motion quilting!
