M302

Hi - I just purchased and setup a Duet Wifi but I am having an issue trying to execute M302 so I can allow cold extrusion and calibrate my extruder steps per mm. If I execute 'M302' or 'M302 S0' I get a message: "Cold extrusion is denied, use M302 P[1/0] to allow/deny it". If I execute 'M302 P0' nothing happens. Am I missing something?


Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.16 (2016-11-08)
WiFi Server Version: 1.03 (ch fork)
Web Interface Version: 1.13

Nevermind - I figured it out. The web interface doesn't print anything to the console after 'M302 P[0/1]' and the Extrude button doesnt work, but if I execute 'G1 E##' it will extrude.
