Fix timing issue in delay check

Changed the condition from `>` to `>=` in the time check `time.time() - self.last_moved > self.delay`.
This resolves an issue where the check could fail on Windows due to `time.time()` having a 16ms accuracy, potentially causing `time.time() - self.last_moved` to be 0.
This ensures the delay condition works correctly even if `self.delay` is 0.
