Smooth movement in all axis

Hi, I want to achieve an smooth movement like the one in this video:
I’m trying to adjust the backslash parameter, is there any another thing I can do? Thanks in advance.

Are you on the Delta stage or the cartesian Microscope?

There are several things you can do. Make sure that your motors are getting enough current - that you are powering them directly from a DC power brick and not just from a wire on a microcontroller. Also make sure you are using brass or bronze hex nuts against the steel M3 lead screws, and that they are clean and lightly oiled. Check that the viton o-rings are still pliable, and replace them if there’s an issue. Also check that all of your mount bolts for the optics module and base and so on are snug, not loose but not too tight.
