I was working on a large form factor 3d printer style machine, and I wondering if there was a way to detect if the motor has stalled or is stuck. I am going to use NEEMA42's here. But for now I am testing things with Neema 17's. Any suggestions? For a bit more context, I am using a raspberrypi paired with a DM542T Stepper motor driver. I do have limit switches installed but for such powerful motors I am guessing it would be a good idea to know if the motor is stuck onto something?

I would think the drivers for such large motors would have multiple alarm conditions built-in, including stall detection.

If your machine will be so large that it needs Nema 42 size motors then IMO you would be better off using closed loop AC servos.

Stall detection during printing isn't reliable because it doesn't work at low speeds. Closed loop is the way to go.
