It can cause your feedback loops to go into fits if you leave them in, especially with large arms that are not well counter balanced.

Bottom Line: if I can, I take them out.

931 experienced this problem using the DeWalt transmission with an FP motor to lift an arm last year. With the anti-backdrive rollers in the arm was stable while raising and erratic while lowering. Removing the anti-backdrive rollers cleared the problem.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
