I have an application that requires a very high resolution on the Z-axis that my current table top CNC milling machine cannot achieve. I plan to use a motorized stage from Thorlabs (scientific equipment): LNR25ZFS. I was hoping to just have to connect the stepper motor to the driver of my current Z-axis (Leadshine DM556E) but I think the driver might be too powerful for the motor. The driver specs state a min. output current of 1.8A and the motor is rated for 0.25A current per phase (see full motor specs here).
Did I interpret the specs correctly? If I need to use a smaller driver, can someone recommend one appropriate for this tiny motor?
