Being able to control delta tower motors with CAN-FD

[Anon1337]

According to the documentation this isn't yet possible.
As I'm about to embark on another big delta build it would be neat to be able to use the 1HCL for example for the tower motors.

@Anon1337 I believe we already have one user who uses an expansion board to drive the motors for a delta printers. The trick was to enable segmentation, so that all the moves are small enough that the straight-line movements implemented by the expansion board are close enough to the ideal delta moves.

I agree that it would be preferable to have the expansion boards support delta movement directly.

@dc42 yes I too believe the segmentation isn't ideal but more of a workaround
