[FeatureRequest]: Support for BiPolar (like a LP player) kinematics

[Kenzu]

Is your feature request related to a problem? Please describe.

Hi

Would it be possible to add support for BiPolar kinematics?
I started to hack the Sculpto 3D printer (it runs smoothieware atm).
Would like to convert it to RRF.
Se this for info https://www.youtube.com/watch?v=OoYPUCgJ-0E
Also this works with a ramps board on the machine https://github.com/unlimitedbacon/BipolarMarlin but 8bit struggles to keep up over 40mm/s.

Thanks

Describe the solution you propose.

Add bipolar support to RRF

Describe alternatives you've considered

Marlin and klipper.

Provide any additional context or information.

So I just found out that the LPC1768 mcu i not supported in RRF only via this port https://github.com/gloomyandy/RepRapFirmware/releases/tag/v3.3.0_16
So it does not really make sense to add bipolar to mainline RRF.

based on the last comment i will close this issue. feel free to reopen it if there is a requirement in the future.
