Battery Indicator
#8
If there is no SD card present, the miniEngine will start up with default settings! If this was not the case, the Arduino was still powered somehow (USB?). To remove the settings permanently, just remove the settings file from the SD card. The next version will have 2 files - one for settings and one for the battery calibration values so that one can delete the settings without losing the battery calibration.

Oh yes one more thing, when I received my stepper (NEMA 23), the yellow and white wires had the ends twisted together. I know these are the center tap wires as per the data sheet, so they are not needed. But this time, I un-twisted them so I am not sure if that also had anything to do with it.

It sounds like the motor has 8 wires and in this case you need to connect the center tap wires - like in the 8 Lead Bipolar (Series) connection displayed here:

You need to make sure that the motor wires are converted to a bipolar setup the correct way.
