Thank you for your response, but all those boards are jibrish to me. Also reading about the software it doesn't seem compatable with the programs I've read about on this forum. I could/probably be wrong in that regard!
As for the travel on the gantry I'll be using the "Hiwin" precision ground screws. Tolerences have to be tight and the rack isn't that precise. Hiwin said i can get away with a single screw with a big motor.
The Ajax System looks good and reasonably priced. I'm wondering if that could handle the motor requirements. Any other thoughts would be helpful.
Thanks
Tony
