  • Re: Stepper motor problem

    [quote user="Schwarz"] Hi all.... We have a problem with our Multimode 3 v. 5.30r3.sr3. Although the stepper motor moves by the manual switch it is not moving anymore by controlling it with the Nanoscope software. We hear some noise in the stm base but the screw is not turning. Did anybody have a similar experience? [/quote] Normal 0 Software

    I'm trying to demonstrate the tip width of a "1-nm radius" tip by scanning isolated features (bumps or ridges). Does anyone have a favorite specimen that has features 1 nm wide?
