Obviously, this is necessary and it may slow things down too much to be tolerable for normal operation. o How does the software know whether the motors are spinning or not? If the software doesn't know, the delay for motor ramp up has to be built into ALL accesses. Remember the TANSTAAFL Principle (There Ain't No Such Thing As A Free Lunch).
