Now that I’ve gotten past that part it appears to be pretty obvious as the calibration goes on. I tend to follow directions pretty literally (my wife would say otherwise). For me, I think the only thing would be if it doesn’t matter which direction the sled is connected until after that step maybe ask that question after the measurement step.
But I’m running into a new problem now that I’ve progressed. Even though it measured the distance between the motors it doesn’t provide enough chain to center the sled. I saw this in another post but it hadn’t been resolved. I’ll actually probably continue this thread here as it’s more appropriate for the new issue I’m having.
