It seems as if the limit again is knowledge/intelligence. > Well, PID_MAX_VEL = 30, and OUTPUT_SCALE = 2.0, so if I understand this right, that sends values up to +/- 15 to the DAC. The DAC, however, cannot produce output greater than +/- 10 V, so the rest of that range will flattop at 10 V. If I'm right about these calculations, that is very undesirable. I'd change OUTPUT_SCALE to 3.0 to keep the voltage output within the +/- 10 V range. Then, you may have to re-tweak the tunings a bit, like raise PID and FFx by 50%.
