    I'm using LinuxCNC and trying to find the data to tune the NEMA 23 motors I bought here, so I need more than the tech sheet .jpg from the website.

    Specifically, I need the following pieces of information:

    Minimum DIR setup time before rising edge of STEP Pulse ____ (nano/milli-seconds) Minimum
    DIR hold time after rising edge of STEP pulse: ____ (nano/milli-seconds)
    Minimum STEP pulse high time: __ (nano/milli-seconds)
    Minimum STEP pulse low time ____ (nano/milli-seconds)
    Step happens on (rising/falling) edge

    I've googled, and there's a perverse frustration in reaching the "hmmm, It looks like there aren't many great matches for your search" message.

    I'm guessing this particular motor is part of another identity which might find "more great matches" when searching.

    Does anyone know how to make better progress getting this information?

    Thank you.

    Those parameters are from your Stepper drivers datasheet. You feed pulses into the driver, not the motor

    Actually, replying to my own message:

    I was confusing what I'm looking for:

    What I needed are the stepper driver specifications: that's where this timing information lives (and is easy to find, duh)
    What I did not need (but asked for above) were motor timing specifications. That's not a thing: the driver takes care of the timing the motor needs.

    So thanks to anyone who read this before I sorted myself out, and hopefully if someone else is seeking the same rabbit hole in the future, they might find this crumb.
