Reduce power to steppers when not moving

Is it possible to assign a pin that is only active when a move is done?

If possible I would like to utilize my drivers "power down" function, which reduces power to the steppers when full power is not needed, i.e. when the mill just sits idle, but still needs to maintain it's position.

One way is to feed motion.current.vel into the "near" component and then use the output of near to set the drives to low power mode when the velocity is zero or very close to 0 , something like:

loadrt near
addf near.0 servo-thread
setp near.0.in2 0
setp near.0.difference 0.00001
net velocity motion.current-vel => near.0.in1
net zerovel near.0.out => PinToEnableLowPowerMode

Thanks, I actually think that I understand what's going on there..

Will test out tonight..

If I want to add a hysteresis to prevent powerdown from flickering up and down, could I abuse the debounce component, combined with an or gate like this ?

I would assume that the or gate would be needed, since the debounce seems to work in both directions, and would would cause a delay before the steppers would be enabled on move, if wired directly to the output.

Or does a timer module exists, with a simple countdown function, instead of using debounce?

And where would I put all of this, custom.hal or custom_postgui.hal?

Use OR plus ONESHOT in parallel to rise current. OR in0 for moving and OR in1 for delayed reduziert

Oneshot seem to do the trick, together with velocity.

The following works out nicely in halscope.
