Anyone see this sort wild oscillation on the DEC axis and know what might cause it? I've already done the obvious stuff like re-checking polar alignment, checking balance, checking for cable snags, and there's no wind.

My AVX is not overloaded; there's not even 4kg on it - Askar V 60mm (2.8kg) , ZWO EAF (0.3kg), ASI533 (0.5kg) - and the mount is rated for about 15kg. Control is via a StellarmateX, guiding is using the ekos internal guider. This also isn't a constant thing. Some nights I don't see the oscillation at all and some nights I do. I'm not using the GPG guider which only operates on the RA axis anyway, nor am I using any form of PEC.

Possibly a red herring, but one thing I've noticed is the drift plot flashing white for a brief moment, as if there is some sort of refresh delay somewhere. I don't see any thing in dmesg to indicate USB errors, nor indications of swapping in top.
