Probe Extension Calibration

When calibrating an extension module, after the measurements with the tip are completed and the joint on the wrist has been measured on the datum sphere without the extensions attached, for each slot configured to hold an extension you will be asked to attach the extension to that slot, and you will need to measure the end joint on those extensions as you did for the wrist itself.
