Bed Mesh Error suddenly appeared.

Ratos 2.1 vcore3 500, all of a sudden the last probe point of the mesh routine fails with this error:

12:59 PM
Unable to parse move 'G0 X250.0 Y F18000.0'

12:59 PM
Unable to parse move 'G0 X250.0 Y F18000.0'

Happens regardless it Adaptive Mesh is enable or not, always the error as above.

Printed fine last night and now this which shuts down the print before its even started.

Suggestions?

Martin.
