Enabling the Single Nozzle Multi Material option in Printer Settings causes the M907 command to be inserted into the gcode. This causes the Wifi Duet to enter an error state and stop the print. Oddly tho it the M907 command is only inserted when the option is enabled. When disabled, that command is nowhere to be seen in the gcode. Attached is an example of the gcode but with the option enabled and disabled.

Enabling the Single Nozzle Multi Material setting is the only way to create a purge block as without it, it will never appear.
