    Hi everyone. Up until now, I've been using DC motors and potentiometers for position control, using the "SMC3 V1.0" code.

    But now I'd like to use stepper or brushless motors. I think I'll use stepper motors... What do you recommend?

    Another question: which code should I use for brushless motors and which code should I use for stepper motors?

    For stepper motors, do I also need to use the potentiometer for position control, or is it not necessary?

    I look forward to your replies, thanks.

    Steppers are not impossible but are uncommon when you have so many relatively cost effective tried and tested alternatives such as servos.

    Steppers can have a lot of vibration, noise, and can lose torque on higher speeds, so actuator speed may be limited.

    But if you are interested in the Stepper path check out @Lebois thread, though even he eventually switched over to using servos: https://www.xsimulator.net/community/threads/srt100-stepper-motor-actuators.16261/

    AC servos are like brushless motors. Control is more like steppers.

    They are price competitive now. There is DIY software on the forum. This is assuming we are talking motors > 400w.
