sounds like you may have inadvertently turned the parallel limit screw
there are three limit screws, the high limit, the low limit and the parallel limit. Its the parallel limit screw that you need to watch out for as even the smallest fraction of a turn adjusts the very fabric of the space time continuum, Sadly there is no standardized position (often it is installed in the place of the low or high limit screw) nor would it have any identification markings . The only way of telling if you have adjusted the parallel (dimension) adjustment screw is that everything that used to work has now been plunged into malfunctioning disarray and you will personally be experiencing feelings of confusion, desperation, anxiety, impotence, panic accompanied by a tendency to walk in circles. Sadly once the Parallel screw has been adjusted this can also alter its very position swapping with ether or both the high and low adjustment screws. The only proven method to rectify any incorrect parallel adjustment is a bit of a sit down with a cup of tea accompanied by a large slice of “try again later”.
