Walking foot problem
 

Hello I’m a newbie!
I am making a 120inch square quilt and am attempting to machine quilt the three layers together. I bought the correct foot for my Janome sewing machine but I’m having problems feeding the fabric through the machine evenly. My stitches are tiny in places despite changing the stitch length.
It feels like there is too much pressure on the foot but I don’t have a pressure foot adjustment on my model of machine.
anyone else have this problem?

My best guess is the weight of your quilt is preventing it from feeding properly. Quilting a quilt that large is challenging, but can be done on a dam, I’ve done it. You will need to have your quilt supported on all sides, without hanging down off your table anywhere. I used extra tables all around my sewing desk, including one beside me on my left to hold up the portion that hadn’t gone through the machine yet.

How does the back look? Do you need to adjust the tension? Have you tried a larger needle? Still, it does sound like a "drag" problem - the weight of the quilt needs support on all sides. I have my machine on a table against a wall, so it puddles into the wall which helps. It's always good to make a test piece - use the same batting between a quilt sandwich similar to the thing you're quilting. That may help you adjust things to work better.

As mentioned-support. Also, put stitch length at about 3. I thought all machines had pressure foot adjustment capability?

Welcome from western NY and happy quilting :)

Silly question...are the feed dogs down?

First, double check that your foot is installed correctly. They can be tricky! Next make a small sandwich, like 6" square and sew to make sure the foot is working.
Having said that, a walking foot is not powerful enough to pull a whole quilt thru your machine. You have to give it lots of help. There should be no drag on the quilt in any direction. The quilt needs to be supported front, back, and left. Extra tables are a great start. If you google 'youtube king size quilt domestic machine', there are lots of videos with suggestions.

Make sure the quilt is supported on all sides and check that your
foot is installed properly. Which Janome do you have? Each
machine is different.

there usually is a bar on the walking foot that must be put on top of the needle shaft bar screw. that helps the foot work correctly. check that.
