With a stepper motor and controller, is there a built in method of load sensing?

I was thinking of using a few stepper motors in a mechanism but I want to be able to limit the force used when too much resistance is detected. Ideally it would have a variable range where limits could be set.
I thought I remembered some feature or easy hack that allows for this sort of thing, but a quick search didn't yield anything.

I think you're talking about a PID Controller?

Yes, there are ways to sense eg the current that flows through the motor, which is proportional to the amount of torque that is generated. Some stepper motor controllers have built in functionality that allow for this kind of sensing.

Not too familiar with what you have in mind, but why not just use a circuit breaker?

Thats what Im thinking. A computer program to monitor the amperage flow and use that as a "sensor" to detect when too much torque is being used when high resistance is encountered.

Yeah, it should be fairly straightforward to program this into an arduino/esp8266 etc.

Perfect, thank you for responding. The other post you made above is what I think I was remembering.

Maybe. I'm not sure what kind of ranges they sense, but if there is a built in method that already has software/hardware control developed, that would seem the ideal solution for me.

Again, what are you actually trying to accomplish? It would really help if there was some sort of context for what the stepper motor is actually for and what the rest of the circuit looks like.

Sorry, I wasn't asking for more guidance. I was able to find everything I needed.
Thank you for helping though.
