Re: DART Linear Actuators for the CIM Motor
Lash in the potentiometer gear mesh will also be a factor in repeatability, with the ones mentioned in the preceding posts. Of course, lash/play in the mechanism powered by this actuator will be (at least) equally important.
Can someone involved in making the demonstration arm shown in the linked video please measure and post the unpowered vertical play at the end of the arm? I think tape measure accuracy would be enough to give us all a good idea of what to expect.

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.
