Extrude backs off before print

Not sure what is happening with the Robo 3D. At the start of a print it does the autolevel check and then orients to the starting position and the extruder stepper backs up two or three revolutions then starts the print with no material in the hotend. I'm slicing the parts with CURA and then sending the gcode to the machine through mattercontrol. Things were running fine but now all of a sudden this happens every print.

 

Add a G92 E0 before G28

 

A line above or same line. I have "G28 X0 Y0" currently. Thanks Mike

 

A line above, should look like this

Code:

G92 E0      ;Reset Extruder count to prevent over-retraction
G28 X0 Y0   ;Home X and Y
G28 Z0       ;Home Z

Though I don't see the point of separating G28 since it really should home in the bed center.
