 Once you have established planar correction, you can pretty much forget that you have anything special going on.  The stage will respond to Joystick moves, and manual focus moves with the controller’s focus knob as expected. ​ Commanded moves will be with respect to the corrected surface, again more or less as you would expect. ​ The main LCD display shows the corrected Z-position and the [[commands:​where|WHERE command]] responds with the corrected current position. ​ If you are curious to see how much correction is actually being made at any particular point, the two-column LCD display mode (DIP SW 1 UP) will show the true encoder target position on the right side of the Z-axis line.  For example: Once you have established planar correction, you can pretty much forget that you have anything special going on.  The stage will respond to Joystick moves, and manual focus moves with the controller’s focus knob as expected. ​ Commanded moves will be with respect to the corrected surface, again more or less as you would expect. ​ The main LCD display shows the corrected Z-position and the [[commands:​where|WHERE command]] responds with the corrected current position. ​ If you are curious to see how much correction is actually being made at any particular point, the two-column LCD display mode (DIP SW 1 UP) will show the true encoder target position on the right side of the Z-axis line.  For example:

 You will notice that as you move around in XY, the corrected position will remain constant, but the actual stage encoder target will change as the correction demands. You will notice that as you move around in XY, the corrected position will remain constant, but the actual stage encoder target will change as the correction demands.
