I haven’t watched the whole video, but I’m assuming what they were showing was ‘move x from 0.00 to 10.00’ with the gauge showing the final move was to (actual) 10.05.

Which with how floppy that rig is, is pretty impressive.

Notably though, those gauges do need to be ‘preloaded’ (compressed into their ‘positive’ range) to be able to measure negative direction shifts, and while it looks like that was done, I can’t be 100% sure without analyzing it far more than I want to do right now.

Also, those gauges provide a degree of preload (not much, but some), which might be taking a bunch of slop out of the system and giving overly rosy accuracy numbers.

I think it’s okay that they use the contract force to remove backlash since they are actually controlling it. In fact, if you could do that well, that’s huge!

I don't think they could do that sustainably while it's actually doing 'the job' though, correct? It's pretty in the way.
