What I would like to try someday is to connect linear encoders while still using rotary encoders. For example, if you have linear encoder resolution of 0.0005", and rotary encoder resolution of perhaps 0.0001", you could position from your rotary encoders just like normal but update the position with linear encoder position. Sort of use the linear encoder to know the position to the nearest half thou and use the rotary encoder for tenth positioning. Or heck with it, just get scales that you can set up to 1 micron resolution :-) But I think the motor needs to be controlled using its own feedback.
