Issue with MoveAxis for Alt-Az mount (Axis 1 not receiving rates in Alpaca / SkySafari)

I’m currently developing a telescope Alpaca interface for an Alt-Az GoTo mount. The application is working well overall and most features are functioning correctly.

However, I’m running into an issue with a key feature:
manual movement using arrow keys (MoveAxis) in both directions.

• Axis 0 (Azimuth) works correctly:
  • CanMoveAxis is set to true
  • SkySafari queries AxisRates
  • Arrow key presses result in proper slew commands with non-zero speed values
• Axis 1 (Altitude) does not work:
  • CanMoveAxis is also set to true
  • However, SkySafari does not query AxisRates for Axis 1
  • When pressing arrow keys, the API sends a rate of 0.0, regardless of selected speed

Only Axis 0 seems to be fully initialized/used by the client. Am I missing something in the Alpaca implementation or configuration that would enable proper handling of AxisRates for Axis 1?
