We have been using Nanoscope IIIa instrument which has recently developed a problem. The e-scanner is not able to image the samples and the features appear to be stretched in one direction. I am attaching two images of the same sample, one taken with the e-scanner and  another with the J-scanner. The stretching in E-scanner is evident.  Any suggestions or help will be greatly appreciated.

 

 

 

another another from the j-scanner.

My first guess is that there is something wrong with your calibration file of the e-scanner, assuming you select the right calibration file. If you still have the previous calibration file from before the last calibration try loading that one and try again. The fastY sensitivity looks wrong ( top of the picture is much more stretched than the bottom), or try re-calibrating with the grid

I have tried using the previous calibration file, but the problem persists. Re-calibration is difficult as I am not able to image the grid.

Is it possible that one of the piezo of the scanner has gone bad and is there some way to check this.
