Big thanks DJ...testing today!


You bet guys! Glad it'll come in handy


I just was able to use the new properties that allow selecting the maximum number of servo position range. WOW! What a nice feature. I was amazes at how smooth my servo's move now. I increased the positions from 180 to 1024 and they are as smooth as ice. Of course I had to change all my servo max/min settings and positions but it was so simple to do and understand.

I'm using EZ Robot HDD servos from an EZB control (of course) by ARC. I was a little disappointed with the smoothness of these servos. Maybe it was the way I was using and had them mounted but this setting let me control that. I plan to play some more with the number of servo position range setting to see what kind of changes I can get in the smoothness of these servos.

Thanks so much!!


Good to know Dave. I have to get rid of some of the ratcheting I have with my servos.


This seems to really smooth the ratchet. If i really pay attention I can still notice it but it's hard to see. Very fast.


Great feature, thanks
