  • Very nice product! I wired 2 boards up to Arduino Due and connected 2 stepper motors, worked like a charm.

    I know this is a bit out of context but I would ask for your help if you have experiance with running steppers very fast with this breakout board. I need to control the stepper motor KH56QM2-951 (http://www.nidec-servo.com/en/digital/pdf/KH56Q.pdf). This motor is rated at 4V, so I used 33% KVAL settings for 12V 3A power supply. This works ok for lower speeds but motor starts stalling as low as 900steps/s at this settings. I would need 10k or more.

    So I tried increasing ACC/DEC KVAL settings but same happens. Any idea which settings are recommended for very high RPM? (Maybe I am missing something in advanced settings).

No public wish lists :(
