Panel due doesn't write to console during macros

[OwenD]

I have noticed that while running a macro (from the PanelDue) that performs multiple G30 S-1 commands, that only the last value is written to the console.

while iterations <= 9
	G1 Z6
	G30 S-1

When I run the same macro from the DWC, all the values are written to the console.
If I add

M117 {move.axes[2].machinePosition}

after each G30 S-1 then the value is displayed.

If I add

echo {move.axes[2].machinePosition}

then the echo is not written to the console of the PanelDue
