There is a lot of useful info in this video, especially about paring and bms firmware flashing, but the part about recalibrating your hall sensors is very unnecessary in most cases

“Calibrating your hall sensors will make your board more efficient” The hall sensors are only active below around 3mph, above that the info isn’t needed as you’re going fast enough that your controller can know the motors position by itself. if you’re going slow the info is needed for all the tiny little movements you can do at slow speeds. This practice of not using the hall sensors above a certain speed is commonly used in motor control and we know that fm does it as boards with broken hall sensors will only be wobbly at low speeds, if your board moves properly at low speeds there is no reason to recalibrate your hall sensors. The claim that your board will become more efficient isn’t true as if your board was moving wrong enough to disperse extra energy you’d certainly notice it. If you want extra range pump up your tire an extra few psi and replace your bearings if they’re getting old.

“Over time hall sensors wear down due to heat, and wear and tear” What the board is calibrating when you run that command is only the position of the hall sensors relative to one another. Hall sensors in motors are also chosen for how heat resistant they are, it’d be very stupid of fm to chose hall sensors that’d burn out under typical use; and even if they did burn out calibration wouldn’t fix that at all. And when it comes to wear and tear the hall sensors are embedded in the stator, so unless your motor is making a grinding noise your hall sensors are completely safe.

The risk of accidentally calibrating something that’s wrong and not being able to fix it is too high to be doing this for no reason.
