This is experimental but we believe we have a good, reproducible way to set belt tension! Let's give it a try.

This method uses an app called EasyTension produced by Hutchinson Transmission. You can get it for iOS and Android so head to your favorite App Store and download it (it's free). More info and links here: EasyTension App

When you first run EasyTension you will see the screen in the first photo, click on the blue FREQUENCY METER and the frequency measurement panel will display as shown in the second screen capture.

SLOWLY move all three carriages to the bottom of the printer so they touch the base. You will be measuring the vibrational frequency of the side of the belt that is not connected to the carriage.

Moving stepper motors generates an electric current that can damage your Duet controller. Even though the stepper motors are not hooked up yet, it is good to get into the habit of moving slowly.
