Yep. My test cube prints perfectly once more with the new firmware and the calibration settings written back to the eeprom again.

I guess I need to make a screenshot of my settings, then re-apply them after loading new flash.

My just completed experiments sure seem to indicate something is screwy:

Test cubes made clacking noises on retraction and didn't print well till I put back the original flash and eeprom I saved off before starting the experiment.
