How do I return my machine to its factory setting?

February 19, 2026

In order to tuft properly, all parts of your machine must be synchronized so that the needle and nozzle push the cloth open to create a tuft. Even a few millimeters of maladjustment can cause the machine to fall out of sync, creating problems. 

If your machine is out of sync, it’s probably because a pile-height adjustment was made incorrectly. Luckily tufting machines are durable, and can often be fixed simply by reestablishing the factory settings of the upper and lower machine bars. 

Factory settings for Duo machine: 

• Upper-machine bar between the two nuts: 52mm
• Lower-machine bar between the two nuts: 43mm

The factory setting should not be moved on the Duo. For step-by-step guidance on how to adjust the pile height on your Duo, check out the video collection that came with your machine.
