Hi there, I'm exhausted on researching so I got a quick question…

Running Smoothieboard 2.0

My 2 phase motor ratings are:
Rated voltage=3V
Current/Phase = 3A
Impendance/Phase = 1 ohm
Inductance/Phase = 4.3mH
Degree/Step .9…

I take it I set my dip switch on my DQ542MA driver to 2.84 peak amp/2.03 RMS setting. Correct me if Im wrong on that, if you feel Im safe to up it, please let me know. In the start up guide, smoothie says to set amp config to your motor settings, it gets me confused since driver setting are set lower than the 3amps, should I still set the config to 3.0?

Thank You!

If the driver reduces idle current, or has a setting to (semi-flow function?), you can probably set your driver RMS current up to the rating of the steppers if they don't get too hot. (If you can hold them, they're probably not too hot.) Some steppers don't respond well to max current though, so you may not see any performance improvement.
