Hello Andy,

First of all, thank you for your great work.

I am trying to control 30 servos with Arduino Mega 2560 but it seems the servos only twitch as I slide through 0-180 to mega write, and I tried to connect only one servo to different digital pins in several times, the results are the same.

I tested with Uno and all 9 servos worked under the same set up, so I imagined there might be something wrong with the firmatta, and I came across this post in 2011:  http://fireflylabs.squarespace.com/discussions/post/1540044

the Firefly version I'm using is 1.0.0.70 64 bit, does it cover for the "buffer size" and "baud width" issues that you mentioned on the post? 

I am using Rhino 5.0 and the grasshopper version is april-04 2014 build 0.9.0075. the Arduino IDE version is 1.6.5

Thank you for your time.

Thank you Andy, I completely overlooked the setting... Everything is working now. Thanks again for bearing with me.
