The present invention relates to a method for controlling a scanning probe microscope having a probe () with a tip () for interacting with a sample (), and a nanoscanner () for retaining the sample () or the probe (), comprising the steps of monitoring the extension of the piezo element () along a first direction (R) along which the tip () is moved towards the sample (), and adjusting the level of the probe () along the first direction (R) by means of an additional actuator (), when the nanoscanner () exhibits an extension below or above a threshold value. The invention further relates to a device () for controlling a scanning probe microscope. 12214142. A method for controlling a scanning probe microscope having a probe () with a tip () for interacting with a sample () , and a nanoscanner () for retaining said sample () or said probe () , comprising the steps of:{'b': 1', '21', '4, 'monitoring the extension of said nanoscanner () along a first direction (R), along which said tip () is moved towards said sample (), and'}{'b': 2', '3', '1, 'adjusting a level of said probe () along said first direction (R) by means of an additional actuator (), when said nanoscanner () exhibits an extension below or above a threshold value, and'}further comprising the steps of:a) measuring a force curve on said sample, wherein said force curve comprises an approaching curve and a retracting curve,b) detecting an optimal baseline part of said force curve,c) optionally detecting a contact point of said force curve, {'b': 3', '32, 'additional actuator () and at least a second additional actuator () the lateral position of said probe, or'}, 'd) comparing said approaching curve and/or said retracting curve with said'}{'b': 2', '4', '53', '2', '2', '53, 'an angle (α), wherein said angle (α) is monitored between a second direction (R) and the normal (N) of a surface of said sample () at a point () of said surface, wherein said probe () is moving along said second direction (R) towards said ...
