Z axis calibration idea

on further reflection, a separate tank off to the side of the whole machine attached with an umbilical to the build tank, that way the water would displace both at an equal rate, it just might work.

this setup could also be used as an overflow cut off switch, the gauge has a contact on top and an adjustable slide with the second contact, this way as the gauge floats up when the top reaches the slide it can activate a solenoid valve to stop the drip flow.
