The image below links to a video of the target mounted with under 10um of perpindicularity error between the target and the motor's rotational axis (that's 5/10's per division on the indicator). 10um is very measurable for the LDC1101, but due to the nature of the encoder it should be cancelled out for the most part. After I get some initial data I will deliberately push it out of perpindicularity and see how sensitive we are to that spec, but for now I am trying to have everything optimally dialed in.

And [here's another video showing the first step of sweeping the turned delrin encoder mount](https://gitlab.cba.mit.edu/davepreiss/ldcoder/-/blob/master/images/rotorNoTarget%20.mp4) that's sitting underneath the rotor. It took some adjusting with a flathead screwdriver to dial it into under 10um error, but seems stable and should be fine for initial testing despite just being a press fit at the moment.
