the only thing i have to resolve is, the extruder whipped out 250mm of filament at the end of the print, which is all rather odd. there's a relative "extruder retract" command in the end.gcode of the cura config that i'm using - it says "E-1" but what actually happened was "E-250" or so, which tells me that, possibly, the G91 command just before it isn't being listened to (or does something different from Marlin firmware) - maybe G91 doesn't set relative *extruder* moves or something, i don't know

That's correct, we changed G91 to affect only XYZ moves many months ago. The code you are looking for is actually M83.

@lkcl, thanks for your report. Can you share a photo of your machine?
Contrary to popular belief, reducing microstepping does not increase motor torque. The torque per unit of angular error remains the same. The only valid reasons I know of for reducing microstepping are to cater for slow electronics that can't generate the steps fast enough, and possibly to shift the vibration frequency out of a troublesome range.
