All machines have some system for measuring position, whether stepper motors or encoders. These MUST have some fixed resolution that can be either moved to (stepper) or measured (encoders). While there are physical positions that exist BETWEEN these resolved points, they cannot be moved to by the motion control hardware. So, all machines have a lower limit to positional resolution. In practically ALL cases, this is much coarser than the numerical resolution used in LinuxCNC.
