Re: Stepper Motor Controllers

One disadvantage of the Newport XPS controller is that the controller
requires its configuration to match the stages that are physically
connected.  If one stage is disconnected from the controller, none of
the other axes will be usable until the unused axis is reconfigured to
be a dummy axis.  For stable setups this isn't an issue.  For
frequently-changing setups this can be quite annoying.
