@dc42 Yep, the period is definitely two cycles per revolution. It's also consistent on all motors and encoders I have, including 0.9 degree steppers and CUI AMT10E2 capacitive encoders.

Here's just one revolution out and back. I marked the shaft and watched as it went. At this scale (and with the other issue resolved), it's more of a sine cosine wave than a sawtooth pattern. Between that and the two cycles per revolution period, makes me think it has something to do with pi, but I couldn't guess what.

@evan38109 Autotune can be hit/miss at the moment. One of the most important things with it at the moment is to make sure you only have one browser running when you use it. There has also been some issues I believe around the rate of running the tuning maneuver with some changes in 3.5 beta. I have more testing to do on it with 3.5.

@dc42 Thanks! You rock!

@CCS86 the main reason that Klipper uses PA smoothing is that it doesn't control extruder jerk, and without applying PA smoothing it's likely that the extruder would miss steps.

@dc42 Thanks! Was just reading this as you replied:
Z probe trigger height second order temperature compensation is now supported. To use it, specify a 2-element array as the temperature coefficient, e.g. "M558 ... C0.01:0.0005"

Just tried the firmware from dropbox, and it works like a charm. Thanks for taking the time to put this out on a weekend! 👍

Also -- and I'm sure you get this a lot -- but I can't get over how easy the firmware update was. Kudos.

Ahh, that's what I was missing. Thank you!
