If you've successfully put a compatible pattern file onto your tablet, then you can import it into the Perfect Stitch app for use by your robot. Here's how you do that.
1. Go to the 'Patterns' tab on the Robot layout screen and tap the 'Import/Export' tab.
2. Select 'import pattern' or 'import folder' (import folder is to import an entire folder of patterns at the same time).
3. Navigate using the file picker by double tapping on folders to where the file is located and select it by tapping on it.
4. Tap 'Import' or 'Open'
That's it! A confirmation message saying your pattern has been imported should show and you can find it in the app now. Great work!
