MihaiP Depends on the stepper motor driver. Count on several seconds per 100 mm, as fastest move. The lowest is as slow as you want!

MihaiP Not recommended. Notebook manufacturers require to use only their adapters, since most of them are not just AC-DC converters.

MihaiP Zero volts is wrong! Possible causes: Power it at 3.3V only! Use analog read but in a 3.3V board! My readout: about 620 (2 V in air) and 310 (1V) in water. You must calibrate yours.
