1 revolution of the control dial on the Proxxon advances the stage 1.0 mm, whereas on my model of the Nikon block 1 revolution advances the stage 0.1 mm. With the large 6" control dial (see top image) I can move the Proxxon stage in increments of 10µ which is plenty fine enough for up to 10x.
One excellent feature of the Proxxon is the ability to move the stage right-left as well as front-back.
I have always anchored my camera and moved the subject. Today I 'dug out' the Proxxon and used it to move the camera; and because of the ability to make fine adjustments to the right-left axis is was a simpler system than having to move the subject which was at the far end of the optical bench.
Despite looks, the system is stable. Proxon movement was smooth with apparently perfect alignment in that ZS-stacked images showed nice clean edges.
