Power usage, FAN, Motor, Idle, Printing

[WZ9V]

I did the FAN off mod to the settings.

Power is measured on mains side 230V AC,

Idle after power on 3.5 W
Start print motor move down, FAN started 9.5 W
UV ON, FAN on 52.6 W
motor up/down FAN on, while printing 8-9 W
Idle after print motor is up, not moving 7 W

the settings do not alow for motor off and fan off at the same time..
WHY NOT ?? what is the point to burning 4 watts into the motor and motor driver after a print is done ??

Firmware change request.. thanks..

Usually the driver is powered to keep the build plate from reversing back down the screw.  At least that's why on my FDM printer.
