I hope it is ok to be posting about this again, but I have encountered a new issue with transmitting DMX data out from my customized M4L patch (see attached)

Everything works smoothly, automation is good, no lag. Seemingly after a relatively constant amount of messages passed from Max to the Arduino (not an elapsed time thing) the output hangs and I have to restart and unplug everything to continue.

Is there some sort of function I need to include in my Max patch to clear the buffer? Is that what's happening? Some sort of buffer overload or something?

Sorry if this is a totally n00b question, but I'm pretty new to this and the other forum posts I've found about this aren't tuned exactly to what I need to do.

BTW, I am using an Arduino Uno / Tinkerkit DMX Master Shield with the SerialToDmx example program which comes with the DMXSimple library loaded onto the board (edited to include the proper number of DMX channels that I am using of course, which is 12) I am also on late 2013 MBP with a 2.7 GHz i7 processor and 16 gb of RAM, so I'm pretty sure it's not a CPU overload issue (lol)
