Motor Controls


The MOTOR CONTROLS window allows to position the sample using motorized stages.



Coordinate System Selector

Selects the coordinate system for the XYZ position.


Sample: Default See Sample Coordinate System for more information.

Stage: Stage coordinates. Might be inverted relative to sample coordinates

Raw Motor: raw motor axis coordinates as returned from the motor controller

X, Y, Z Position Indicators

Shows the current position of XYZ axes. If an axes is simulated, the background will be gray If an axes is in an error mode, the background will be red

Query Position

Queries the position of the motor controllers.

Zero, Zero All, Clear Zero

Establish relative origin for selected axes.


Move sample focus in arrow direction by defined step size. Keyboard shortcuts: arrow keys, PgUp, PgDn Note: holding the Ctrl key while stepping reduces the step size by a factor of 10

Reinit Motors

Reestablish the connection to all motor controllers.


Open motor alignment controls Motor Alignment Window


Specify tip/tilt of objective optical axis relative to the motor axes

FastZ Goto Zero

Move the FastZ positioner to its zero position

FastZ Target

Sets the FastZ target position

FastZ Feedback

Shows the value of the FastZ position sensor

FastZ Calibrate

Calibrate the FastZ position sensor

FastZ Arrows

Move the FastZ actuator by defined step size. Shortcuts:

  1. Drag focus using mouse (red star in axes on left side of window)

  2. Hover mouse over axes on left side of window and use scroll wheel


holding the Ctrl key while stepping reduces the step size by a factor of 10

FastZ Align

Align the FastZ coordinate system to the sample coordinates.
