Here is a mcaro that probes the center of a spave in the X axis and returns a distance value.  To use position the probe inside of the X axis space then call M1056.

It can be called from a Gcode program, the MDI line or from a button script.

It wil probe the Xaxis space and return to the center point ,then return the distance value.  To be accurate on distance you must have set the Probe tip Diam on the settings page. If the Tdiam is not set the probe will still return to center but the distance value will be off by the amount of the tip diameter.
