help
Specify the duration of the stepper step pulse time. This
setting applies to all stepper drivers controlled by the
micro-controller. If this value is set to zero then the code
will "step" and "unstep" in the same C function.
The default is zero for 8-bit AVR based micro-controllers, as
it takes a little over 2us to step and unstep with this
setting.
The default for all other micro-controllers is 2us.
CUSTOMIZING THIS VALUE DOES NOT IMPROVE PERFORMANCE!
