Your experimental work on the voltage difference is fascinating, I appreciate you sharing the link to the demo. There's something about seeing results come off real hardware that you just don't get from computer simulation. Watching your setup brought back some of the excitement I felt driving my Makerbot via a stylus input 15 years ago (probably the last time I seriously engaged with hardware) [1]. Thanks!
(I mention this so more people can know the list exists, and hopefully email us more nominations)
The anomaly report pdf is quite long. The relevant pages for the bug report are 51 and 52: https://www.ibiblio.org/apollo/Documents/contents_of_luminar...
