Stage range and location errors

Request Help

Hi，All

I recently calibrate the stage range with etalon，found the range is about 10mm in XY direction， is it reasonable？

I wonder the travel rang is sufficient for most users？

Second question，Since a stepper motor used，why not remove the gear and drive the thread directly to avoid the return difference？

Thanks

The stage range is nominally 12mm×12mm. This is a compromise between range, stability and overall size. The OpenFlexure Microscope is not a universal microscope, there are tasks where it excells but it is not possible to do everything.

The stepper motors on the microscope have internal gearing (about 64:1 ratio). There is backlash in that gear train, so removing the Microscope gears would not actually make much difference in that respect.
