Functionality and features

This document lists features and their requirements. It is meant to be used both as documentation and as a template for test protocols.

Base features

Power up motors on start
- The humming of the motors indicates that the machine has successfully started
Persistent configuration
- Winders previously configured with Blynk will load the Blynk Wifi Config
- On machine-start the last known configuration is loaded and used if valid
- On change (in the webfrontend) the current configuration is saved
Standalone access point
- If not disabled the machine creates its own Access Point (AP) allowing for an independent operation of the machine
- If no external wifi is available / specified, an access point is created (even if previously disabled), preventing the user from locking himself out
- Connecting to the access point will automatically redirect the user to the machines webfrontend (Captive Portal)
- The Frontend can either be reached via winder.local (ESP runs a DNS Server) or via the Winder IP (in AP Mode 192.168.4.1)
Autoupdater
- While in Standby, the machine will periodically check for updates when connected to an external wifi, and install them on the next machine-start if possible
- The configuration is rolled over by saving it to a different storage partition that is not overwritten by the update
Load Detection
- When Winding the Spool motor automatically speeds up or slows down so the filament constantly stays at tension
- When a function with position accuracy is needed the Ferrari Motor performs an sensorless auto home against the motor coupler (if not previously homed)
