X-in/1-out non mixing extruders problem with `max_extrude_cross_section`

General Discussion

@Sineos

the first code is from slicer without modifications (up to macros, but ; CP TOOLCHANGE LOAD section is as-is)
you can see it with lower rates at link above

Blockquote
Due to the long length of 140mm, this process, Klipper may throw a Move exceeds maximum extrusion (##.###mm^2 vs 0.640mm^2) error, or similar.

Regarding PA, attaching log of running:

tried on the same failing line increase smooth to 0.4 and 0.8 and it still fails so maybe this command is too harsh, but on real print, smooth time is what helped me.
