Max speed and acceleration ?

[Philippe Tourmeau]

Dear Users

What is the max speed and acceleration to drive my Nema14 stepper please

arduino + Tb6600 driver.

Kind regards

Philippe

Maximum speed for one motor using run() is about 4500 steps/second. Your mileage may vary depending on details, but it won't b faster than that. That assumes you are using an Uno or equivalent.

Out of curiosity, why are your using a Tb6600 driver? Seems like overkill for a NEMA14 motor. What resistance do you measure across a coil?

I use ny TB6600 for everything/anything because that is what I have.

thanks, if I understand correctly : 4500 is the max value I can write in the code ... (setSpeed )?

[Jim Larson]

Actually, you can write any number you like. But (assuming an Uno or other ATMEGA328 based Arduino clone), you won't get more that 4500 steps per second to your motor. And that's a maximum value, you may end up with less if anything else happens in your loop() besides the call to run().

And remember, you need to call setMaxSpeed() with the speed you want to use (or greater), then move() or moveTo(), then constant calls to run().  There is no need to call setSpeed(), it will be overwritten. For more detail, you may find this helpful:

HTH!
