This is what I figured. I guess it's off to the old drawing board.
What about a source for "accurate" pulleys. I am concerned about the 'true' ratio of the pulleys. I know I can take measurements once I am up and running, and back it out in the software; but I want to be on the money from the get go.
So now my questions turn to...
Sources for pulleys? Belts?
I am looking at ~450oz steppers, so where can I find adapters for the motor shaft to the pulley? |
