ORob's Stepper Brakes

This board ensures that axis drop is prevented in cases of power failure or controller reset. In the absence of power or signal, a normally closed relay set is used to short the stepper coils, resulting in a significantly slower movement that allows the stepper to find its resting place smoothly. On a 3D printer, this means your bed or axis will slowly let itself down without breaking anything. Every save your Klipper config without parking your 10lbs heated bed first?? On a CNC this could be your Z axis gently lowering your tool if you forget to park it or have a power failure. 24V power with a 5V controller signal. This one board can handle both coils for ultra slow and silent descent of 3 steppers, or louder decent of up to 6 steppers. In Marlin you can use Gcode to enable a pin to unlock your steppers before or after a print, in Klipper you can clone your stepper enable pin. In the event of a power failure, this will engage by default. *Note-you can not resume after a power failure, the bed or other axis will slowly move. The axis is not locked in place.   More info and questions here - https://forum.v1e.com/t/orobs-brakes/43374
