The routine I am referring to is the slowing when it only has a few MM of filament to lay down. Cube3 does all kinds of different dances when it does this. And that is where Marvin works so well as a benchmark.

Noisier huh.... I can see that. In the firmware upgrade reports it talks about speeding things up and eliminating some unexplained pauses... or maybe they were explained and later forgotten about.

Anyway, you might be starting to see why I want to compare the gcode part of these files.

I guess I should share my 3DB results... 3D Solutech clear... I always face Marvin to the right.
When you use the left spool, I use the right as my "face side" of the print.
