UNSOLVED M302 not preventing cold extrusion for Gcode
I added an
M302 S180 R180command to my config.g but it does not prevent movement with Gcode, if I do
G0 E-10the extruder motor will turn regardless of temperature.
The only effect of
M302is to gray the extrude and retract buttons in the UI.
Is that normal?
I'm using 3.2beta4.1
Which Duet are you using?
Duet 3 MB6HC with 2 toolboards.
I think cold extrusion is not yet prohibited when the extruder is connected to a tool or expansion board. I will check.

I too am having this problem. 6HC with tools on 3HC.
Having a small extrusion in toolchanging scripts.

I can confirm this behaviour as well using a 6HC with 4 tool boards. It doesn't respect M302 P0. Running 3.2-RC2
As a workaround, I use this in my toolchange script:
if heat.heaters.current > 190 G1 E10 F1000 ; extrude 10mm
