Hi.well I have reset the estop. I have the leds showing ok for the smooth stepper.HG08 BOB and on the motor driver.I have 5v at the BOB at the VCC pin but this go's down. to 2.69v on the, other output pins.there is no sign of voltage movement at the pins during jogging in Mach 3 and the motor does not turn.I have tried changing the pins in mach3 to high and low and also a number of pin numbers but nothing happens.what am I doing wrong.
