This has absolutely nothing to do with "Easily tuning your stepper motor". It is a straight up advertisement for their driver. Oh, and a waste of time.

Thanks for saving me the time

Indeed!!! and a good example about how not to read the teleprompt

Isn't better to have idle percent lower or higher?

Me looking at my 3d printer stepper motors trying to understand. I'm in trouble this my 3d day with it.

I know nothing. How about labeling what the blue/green traces represent?
In addition the traces look very similar, so when transferred to a mechanical system are unlikely to make a significant difference. How about demonstrating how different those differences can be in a mechanical system? |
Thanks for what you have done so far. :-)

Hello Mark, blue and green traces are the current waveform of the motor windings. They should be similar and just 90 degrees out of phase. The missing step there at the bottom trace causes the motor to jerk more and make more noise. A few consecutive missing steps can lock the motor, which is very harmful. In the second graph, there are more current ripples at the bottom trace. Disadvantages of current ripple include power supply noise, increased vibration/audible noise of motor, increased heat and reduced efficiency.
In summary, we want to have the waveform that is the closest to a sine wave.

Mark Horton You're welcome!

Instead of speaking freely and naturally, trying just reading verbatim from que cards...
