What happened?

Expected result At end of print, my GCODE is: ... G28 X ... G90 ;absolute positioning G1 Y200 ;move Y forward to present print

Observed result Console displayed "Error: G1: intermediate position outside machine limits Finished printing file 0:/gcodes/Shooter-Disc.gcode, print time was 0h 10m" G1 Y200 was never executed.

Steps to reproduce Type in G28 X into DWC command line produced same result
