[3.3.rc3] ignores M84 Snn

[o_lampe]

As the title describes, I can't set a S parameter behind M84. It doesn't stop the motors after 'S' seconds.
TBH, I didn't wait 'S' minutes.
M84 alone works.

@o_lampe M84 S was introduced to set the idle timeout in seconds but perhaps it would be a good idea to add another parameter to M906 to set the timeout using that code as well. I'll discuss this with @dc42.

@o_lampe It works for me. Is it possible that your idle factor % is just too high? You can set it via M906 I (e.g. M906 I30 reduces the idle factor to 30%).

@chrishamm
My idle is 30% and kicks in after 10sec.
I tried M84 S20 in a macro and from console.
I can hear the motors get quiet after 10sec, but they don't shut off after 20 sec.
FWIW : Duet2WiFi on a Delta.

@o_lampe If you want to power off your motors, use M906 I0 and specify the timeout via M84 S. There is no distinct control for standby and motor shutdown.

@chrishamm
M84 is the direct way to disable drivers and thereby shutdown motors. M84 Snn should do the same, it's explicitly written for this purpose.
