Machine forgets that it has been homed

MJLew

My printer (Duet 2 Wifi firmware 3.2.2) has developed a recent habit of 'forgetting' that it has been homed.

I home by clicking the home x, home y and home z buttons in the web control and they home correctly but a short time later the buttons revert from their homed state to the un-homed state. (The X, Y and Z homing buttons on the PanelDue show the same status as the web controls.)

I recently changed extruder and had to change a few bits on the config file, but have made no changes to homex.g, homey.g and homez.g.

config.g

M122 does not seem to report any error.

M906 X400 Y400 Z400 I30                 	; set motor currents (mA) and motor idle factor in per cent
M906 E310 I0								; extruder current (zero idle for reduced heat)
M84 S30                                        ; Set idle timeout

When you changed the extruder stuff you also added I0 meaning your idle current (for all motors) is reduced to 0% after 30 seconds. So you're turning your motors off which marks them as unhommed.

@Phaedrux Thank you. Yes, that seems like it will be the problem. I wanted the extruder to have zero idle, not the others... I'll change it and my silence will indicate that the problem is fixed! Thank you.

Unfortunately that idle power is for all drives, not per drive.

You can use M18 to turn the extruder(s) off at the end of a print job.
