3331 has a 1.8° step angle, so that's 200 steps/rev or 3,200 1/16th steps/rev. For 60 RPM, you need 192,000 1/16th steps/minute or 3,200 1/16th steps/second. I peeked at the C source and made the following script, which gives this output: stats for 200 step motor ======================== 1062_1 STE...

Velocity resolution is 1 1/16 steps/sec - you would have to convert to RPM with actual steps/revolution to know the RPM resolution. Timing is very consistent/precise, otherwise USB wouldn't work, or the stepper would misstep, etc.. -Patrick OK, interesting. The DLL takes a double-precision float fo...

Hi, I am using the 1067_0 board for controlling the velocity of a stepper motor. When I command 60 RPM, I measure an actual cadence of 60.685 RPM, averaged over 60 revolutions, with a standard deviation of 0.387 RPM. I do not see a specification for how accurate the velocity control of this board is...
