Turn the coarse adjustment clockwise until the platform of the NanoMax begins to
move. By use of the fine adjustment, sub-micron resolution is now achievable.

3.2 Stepper Motor Drives
To ensure that a particular stage is driven properly by the system, a number of parameters
must first be set. These parameters relate to the physical characteristics of the stage being
driven (e.g. min and max positions, leadscrew pitch, homing direction etc.).
To assist in setting these parameters correctly, it is possible to associate a specific stage
type and axis with the motor controller channel. Once this association has been made, the
server applies automatically, suitable default parameter values on boot up of the software.
Note
To ensure correct operation, it is important to select the correct stage and axis type
as described above. Selecting an incompatible stage/axis type could result in
reduced velocity and/or resolution, and in the worst case could cause the motor to
run into the end stops or home incorrectly.
