For what it's worth, I just had a step timing error that I didn't expect with my simple printer.
Duet 3 Mini 5+ ethernet
300mm bed slinger with 2 independent Z steppers (G32)
I'm running older beta firmware: 3.6.0-beta.3+1 (Didn't have time to get the latest one before this print)

The only thing I changed tonight from the last prints on this printer was to put:
M572 D0 S0.050
Into the console before the print so I could see what a different PA value would do for my 85A TPU print at a low (25 mm/s) print speed before I dedicate a value in config.g
I hope this might be useful.
