Reduce motors to idle current when machine status is "Busy"?
-
Hello,
My machine is in a "busy" state for long periods of time where I just have one stepper motor (a peristaltic pump) running. Is there a way to get the motors that move my X,Y, and Z axes to go to their idle current (i.e. 30%) even when another motor is on? My M84 is set to 10 seconds but since the machine isn't going "Idle" this doesn't help me. l I would prefer not to disable them and have to rehome.
Let me know if anyone has any thoughts.
Thanks!

You could manually set the motor current for all the “unused” axes before you start the longer move with M913, and reset it to the old values (100 %) after you're done.
Maybe having the idle current applied to each axis separately is something for the firmware wish list? That is, Y goes to idle current after n seconds if only x is moving. But that would probably change the position of the head due to less stiffness.

@marvineer Thank you! I was not aware of M913, and had just been trying to mess with M906 but this is exactly what I needed.

@jonathanbrent if it's a Duet 3 board then you could also look at M917.
