Preview: Motorized microscope XY-table for stacking (stepper motor)

I have equiped a standard Leitz microscope table with stepper motors. The height axis will also be modified, so it will be possible to control all 3 axis. The idea behind this project it to be able to use the whole platform for micro photo stacking. So the whole table will be "scanned" and then the height will be changed and so on... At the end you will have a photo with the full maginfication of the microscope and even of the whole platform. Due to the height adjustment it will also be sharp from bottom to top. The complete process will be automatic, so you only have to set start- and endposition.
