Precision Microscope Stage

Projects

Hello All,

I am trying to build a low cost microscope stage that has a step size of about 1 micron (ignore details like table stability and tolerances from machining). I was wondering if any has thoughts if a stepper or odrive driven servo would be best for this application.

Thanks

I suspect a stepper motor with a gearbox will work well for your application. ODrive could also work but you’ll need a very low cogging torque motor, high gear ratios, and precise encoders. Use a servo if you need high power density
