Is it possible to switch an outputpin dependend on “stepperdriver active” or “was active in the last 30 sec”? Goal is to switch a coolingfan to on only when the drivers are in use.
You can setup a switch to read any gcode, including those that other modules use. so you could set a switch to turn a fan on/off based on the stepper driver on/off gcodes.
There is no way to do this for when the steppers automatically turn on when a movement is requested.
If you have a smoothieboard you could do that by soldering a wire between a driver enable pin and a mosfet control pin ( all are broken out )
