This is using my Universal PWM controller, so no step pulses were happening anywhere in the system. I did a 2" diameter circle in 10,000 G01 line segments. It did it in 13 seconds. A close sibling to this board is the Universal Stepper Controller, which can output 300,000 steps/second, and should have the same performance on short vectors. If you need over 750 blocks/second, then you just get a faster computer. In THEORY, a 2.4 GHz computer ought to be able to do close to 3000 vectors/second. Practically, I suppose it would come out somewhat less than that. Your machine would have to be FLYING for you to actually need 3000 vectors/sec!
