This is great news, now you’re a specialist on it :slight_smile Well done, Mate!
Yes, True Drive is mainly for configuring the base Simucube HID and them most common settings used in filtering.
Granity Tool is mostly used by power-tuners to access some hidden configuration parameters for the servo-drive itself. On Simucube 2, these aren’t even accessible any longer. But Granity is still required on Simucube 1 in case we have problematic cases, which doesn’t happen very often, but if it does, sometimes the only way I could recover was via access to Granity.
Anyway, you’re sorted, now enjoy your dd wheel
