+== Home of the guider probes ==
 
 The guider probes are on absolute encoders so the purpose of the home is simply to move the probes 90 degrees from each other.   In the near future we will likely change the end position of the home to be mid range on axis.

+== Move of the guide probes in their X and Y coordinate system ==
+
+The probes actually move along a annulus and have a swing arm moving from that position.  This results in 180 degrees of motion (overlapping for each probe).  While one
+could reference these angles of motion (in degrees) we usually fall back on a X and Y coordinate transform which are nearly aligned with the tracker X and Y coordinate
+system.

+One can move the probes in this X and Y coordinate system:
