Hi Dlang, thank you for your input.
1/ “1 side will mean you measure the actual position of the arm- if the belt stretches”.
This may not be so important, as the tolerances are loose; @ 5mm top and bottom of a 300mm ball screw.
2/ the increased accuracy of being on the 5 side
I do not have any space to fit an encoder on the 12mm shaft at the base of the ball screw.
3/ what resolution
it is a CUI AMT102
How precise? I hope it is possible to train/code the ODrive/Motors to stop within the 5mm from top and bottom of the ball screw. A 300mm ball screw using 290mm.
D, if you can see any foolishness with in this text, please feel free to intervene.
As I’m a here from an earlier part of this century, not growing up with this new technology, I may be on the wrong track! however that doesn’t I can’t learn something new with the grace of mind of bright young people, such as yourself
