@droftarts Hi, I found a solution on my problem here on the forum by deckingman. I haden't defined a Tool for filament loading, I added M563 P0 D0 H1 to the tool section and now it's working.

I can control everything in the machine using the Duet Web interface, except the Extrusion Control buttons.
I've doubled checked everything, the Tools seems to be set correctly, it's heated up and still "Extrusion control" is greyed out.
I have tested the extruder motor with M563 P0 D0 command and the motor is working. How do I enable Extrusion Control buttons? The Printer is an BLV mgn Cube.
