Electronic – What type of motor can provide smooth motion at low speed around 0.1 to 1 mm/s

motorspeed

I am building a stage for tissue cutting and the motion of the stage should be very slow and smooth. The speed range is 0.1 to 1 mm/s. I got a stepper linear motor from PI (M230.10s), I test its speed at 0.1 mm/s and the chatter is 3 times of the setting value.

I hope the motor can motor can move very smooth with chatter around 1%. Is it possible?

One option, of course, would be to add gear/belt/leadscrew drive to the stepper so it can be run at high speed while the mechanism it drives operates at low speed. This way, it'd act very much like a long lever. A large ratio of motor to motion yields MUCH smoother travel and higher torque.
