| Sometimes the image is improved by withdrawing and re-running the autotune procedure (the resonant frequency might have changed). The autotune procedure will make changes to both the drive amplitude and drive frequency. | Sometimes the image is improved by withdrawing and re-running the autotune procedure (the resonant frequency might have changed).

| - | Sometimes the image is improved by lowering the set-point amplitude a few clicks. For example, this might fix parachuting. | + | Sometimes the image is improved by lowering the set-point amplitude a few clicks. For example, this might fix parachuting. Minor changes to set-point amplitude can be made in real time, during imaging. |
| Another thing to try is a slower scan rate. The price you pay is scan time. However, I've found that you actually save time (and headache) by taking a single high quality slow scan rather than a bunch of quick ones with little parameter adjustments in between. I find that adjusting the rate so that the scan speed is <10 micron/sec works well in nearly all cases. | Another thing to try is a slower scan rate. The price you pay is scan time.
