      Hi all,
      I want to know the speed in revs/min of my stepper motor when it's running in constant current mode. The object model currently doesn't provide this information (AFAIK).

        @nikscha I'm a bit confused by the term constant current? Isn't that the regular mode and the G1F-value indicates the speed?

        I'm currently playing with a BLDC motor in constant torque mode. It is controlled by simpleFOC and their step/dir interface.
        They also support stepper motors and have the option to read out shaft_velocity in rad/s. This value can be multiplied by 9.55 to get RPM.

          @o_lampe Sorry, you're right, I must have been tired when writing this. I meant constant torque mode!
