Stepper Brake Support



  • Request to add support for Stepper Motors with electromagnetic brakes.

    Normally locked, apply 24V power to release the steppers.

    Some brakes consume anywhere from 5-15W @ 24VDC, so multiple Z axis steppers could be driven by either an Extruder Heater channel, or a Fan channel.

    More likely to be the case with Duex5 expansion boards, since they have more Extruder Heater channels.

    Would be nice to be able to assign a Brake channel to an Axis, so that the steppers are locked normally, and unlocked with Z axis movements.
