OK, I should have known you didn't have my PWM servo amps. Yes, I have gotten confused who has what.
The resulting resolution with the resolver board is 204800 counts per inch so the motion is extremely smooth. I should post a video of my tenths indicator with the machine moving at .00005 inches per second. It is perfectly smooth. If not for the indicator you would never suspect it is moving. To go from that to full speed rapids (conservatively set at 200 inch/min on mine, limited by the amps and machine, not the Pico or Mesa devices) shows just how good these servo setups can be. |
Wow, 66666 : 1 speed ratio! That is pretty impressive.
