Is it reasonable to expect this controller to drive a stepper motor for load positioning? Is there a product that the Portenta H7 machine controller can interface with to produce viable step pulse rates, with similar performace characteristics as seen is a 3d printer?

The machine control uses slow drivers (TPS4H160) to driver the 24V outputs.
I don't remember exactly but I think it was at least 200 µs to raise the signal up to 24 V.
I don't know the requirements for a stepper driver but it might not work.
I am grateful for you reply. I am inclined to believe that you are correct.
That being said, is there any way that the this portenta machine controller CAN control a stepper? As in, some additional shield, or connected components i could learn and use to do this?
Has anyone used this controller for steppers, or does any documentation mention such a use?
It might be enough to use with a driver like this one: https://www.omc-stepperonline.com/digital-stepper-driver-1-0-4-2a-20-50vdc-for-nema-17-23-24-stepper-motor-dm542t
I have controlled a stepper motor with the PMC.
I used a DM556T stepper driver and Nema stepper motor and pretty much followed this guide (you just have to use the digital_outputs.set command instead of digitalWrite):
(Note the guide uses a TB6600 but it worked just fine for me using the DM556T)
To just control the stepper "manually" with digital outputs is actually very simple.
However I am still trying to figure out if you can use the AccelStepper.h or Stepper.h libraries with the PMC...

I will definetly get so.ething with microstepping, thats a good idea.
Does anyone know the specification of pulse speed capability of the portenta, and which pins are best for it?
