Once your device connections have been set up, you can modify them at any time. Settings can be modified across the network. There is normally no need to reattach the EC device to the EmbroideryHub computer. The device only needs to be reattached if the Wi-Fi settings have changed or if you want to set it up on a different computer.
Caution: Make sure the power LED on the EC device is solid green before double-clicking the device icon in the main window to access settings.
