I will do these tests tonight when I get home. However, the speed not being controlled behavior was also just giving single commands to a single servo. It was weird. I was trying an S2500 and the servo jerked very fast. I tried, say, S100 and it would still go very fast. Then, I gave up trying to control the speed and copy’n’pasted a command from earlier (that had an S argument) and the servo went soooooo sloooow that I had to look down at the 'bot to see why my command didn’t work - it was, just going really, really slow with the S100 setting. So, I got proud of myself and after a few commands one servo went really fast, while one was really, really slow. It was intermittent being able to control the speed of either a vertical (knee) or horizontal (hip) servo. I tried to adjust the baud rate but if I changed it from the default that came up when I launched the SSC-32 Terminal program, it wouldn’t work at all. And, 9600 was not the default so it did not work. I did find some troubleshooting in one of the many manuals I have regarding jumper settings. I’ll double check all my connections, I’m just happy that I finally got my old Hexy to start moving.
