Janome Coverpro 2000CPX: Differential & length dial interaction

We are thrilled to offer you some expert hints and tips from Chrystal McCart, our Janome Canada artisan living in Northern Ontario, and who sews on our Janome 2000CPX and our Janome Skyline S7.  We think you will benefit from this post as we often get asked questions pertaining to this topic.  You can find Chrystal on Instagram and Facebook Ed. 

The Janome Coverpro 2000CPX is a coverstitch machine that will take your projects to a professional level. It can make a decent hem be the perfect hem.

But before you start racing through hem after hem enjoying how easy the Coverpro makes them, it’s smart to take the time to understand the machine, and how different settings interact and affect one another.

The two numbered dials on the right hand side of the Coverpro 2000CPX machine are the differential feed (bottom dial) & the stitch length (top dial).

Stitch Length: How close together each stitch is.

Differential Feed: How much speed/pressure is being exerted on to the fabric.

A fine balance between these two is required for each type of fabric, as well as to accommodate varying thickness. ie, two layers vs four layers.

Stitch length plays a very special role when it comes to making it over thick seams smoothly and with ease. By shortening your stitch length slightly, and going slowly with a light touch of the pedal, you can go over very thick seam joints without jumping or skipping stitches, nor see a visible difference on the hem once completed. This trick comes in very handy when at an intersection of 4 seams all folded over!

This is a green cotton spandex fabric (95% cotton, 5% spandex), with two way stretch and recovery. It is folded over to showcase how the stitches interact as they would on a Hem. I am showing how the results on a two needle hem. The needle tensions are set to 5 (middle), and the Looper tension is set to Tight.

With differential set to 1.5, you can see how Increasing the stitch length from 1-4, not only affects the length of the stitch, but also the width. This is because the stitches are being pulled over the length of the fabric as you stitch, and with this, the hem is losing its elasticity; You cannot stretch threads that are already pulled taut.

Your differential Feed dial should be viewed as your secret weapon. Adjustments to this dial will fix a multitude of problems you may encounter such as Wavy Hems, Horizontal Stretch, Gathering & Tunneling.

For the perfect hem on the Janome Coverpro 2000 CPX, it is easy, and only involves adjusting these two dials! Beautiful hems are in your future!
