First of all, I'd like to thank Chris for the untold hours and devotion he's poured into this project. It has been a dream of mine to build a small arm since I was a kid but without a good way to control it, it's just eye candy. The AR2 software has really changed that. I would compare it to what MACH 3 did for those wanting to build CNC mills and lathes, it opened up a whole new world. The AR2 software was the turning point for me. I've enjoyed the journey of actually building a small arm like I've always dreamed of and now it will actually be a useful tool thanks to your software. I really respect what you're doing for people with this project. Any chance the AR2 software will run on an older XP laptop? I have one that I would love to dedicate to the software and my robot.
