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

[NNygren]

The homex.g file generated by the RepRapFirmware Config tool ends with G1 H2 Z-2 F6000 ; lower Z again and commenting that out stopped the print head from crashing into the bed after homing.

Did you forget to include G90/G91 around those lines? Assuming the homex.g file raised Z by 2mm earlier in the file.
