Thank you! It's pretty heavy, it weights 4lb 8oz. I tried to use cheap ones in the beginning as well, for money reasons, but I quickly realized that they wouldn't cut it.

I got mine from a seller from amazon; however when I checked back they don't sell them anymore, otherwise I would give you the URL. I wish I had better news for you; I ended up buying two myself trying to get one that worked. Good luck

For this project I did not use Gcode to create the image; instead program draws from binary data.There are pen plotter on instructables that do use gcode though, you can search their site for "gcode + plotter" and will find lots of examples. Have fun & good luck.

I don't think that would be possible, mainly because the Arduino needs to connect to the RX, TX pins before the RS232 chip is involved.

To be honest I never got that robot to walk; at the time I was convinced that the motors were not strong enough for a quadruped. With body balancing they might have been up for the job, but I didn’t know how to implement that.The original code was written for robots using "Dynamixel" servos, it could be part of the reason that you aren’t getting the range of motion you expect. I had to make a change to the leg lift height for example. Ultimately, I used the parts from this robot to create a hexapod and swapped over to the "phoenix" code base.At any rate, I found this, maybe it will help you:http://forums.trossenrobotics.com/showthread.php?7...Let me know if you have any other questions, I will do my best to answer them.
