Ahoy, the motor is set using the `set_speed` method which was broken until @RogueM fixed it today, actually.

The method takes a value from -63 to +63. Slightly odd, but this is the range as understood by the motor driver chip.

To get the fix, you should run:

```
curl -sS get.pimoroni.com/flotilla | bash

```

This will ‘refresh’ the git clone initially made by the rockpool (or flotilla) installer if that is what you used initially. If you installed the API by your own method, then ignore, you obviously know enough to roll the change on your system!
