Little Step-U and Oriental Motor PK244m stepper.

Greetings again.

I've worked through a couple issues with my BS2px and the little Step-U controller. I finally got the baud right and was able to communicate with the controller. After successfully getting the motor to step in each direction, I decided to ramp it up a little. Just as I got the speed via the {A200} command to step, anything faster than 220, the motor runs rough at best and anything faster than 250, the motor just vibrates and makes noise. Is there something I'm missing not being able to get the stepper to move at faster RPMs? I know the Little Step-U will step at 5000 steps per second or about 700 rpm for my motor. Any thoughts are appreciated.


Fred

    I think I may have found the problem. I need to use the ramp-up feature for higher speeds. I just can't start it at say, 3000 steps per second as the motor won't respond. If I ramp up to it, I think it should work. Any thoughts?
