I updated several of my Mini's at work to the new firmware and sliced with minor modifications to the stock IS profiles. On this particular print which were several tall parts, the Y-axis seemed to slowly but consistently lose steps, resulting in every part having a slant backwards in the Y direction. Two parts in the batch are taller than the rest however and the section of those parts that were taller came out straight up and down, so whatever was causing the drift stopped once it was jumping between less parts.
Any ideas what this might be? Y-axis belt tension just slightly too high for the new higher accelerations?
On my Mk4 at home I was having a lot of issues with lost steps on the X axis with input shaper and I eventually just had to loosen the belt from the factory setting quite a bit, and it was a pretty sensitive adjustment. I'm wondering if it'll be the same with the Mini's- belt tension sensitivity will be much higher with the higher accelerations to ensure there are no lost steps. It's just interesting that it was a consistent drift rather than a big random step like how I'd seen it happen on the Mk4.
RE: Y-axis Drift
And the material is some very old PLA, so the stringing may be due to moisture. Haven't dialed in retraction settings.
