Sequential printing extruder clearance ignoring brim width

[bennierex]

What happened?

When printing squential objects, SS only takes into account the extruder clearance relative to the object itself. When using a brim, the extruder will collide when printing the brim of the next object.

When printing the brim of instance 2, my BLtouch collides with the printed instance 1.

Version

2.4.58.5

Operating system

macOS Ventura 13.4.1 (22F82)

Printer model

Ender 5 plus running Klipper

I’ve experienced this as well, so it’s not isolated to you

[supermerill]

Brims are printed first, before any objects, and so nothing should collide.
Please help me to understand where is my mistake.

[bennierex]

My brims are printed per-object...

[supermerill]

oh, yes.

[supermerill]

mmm.
if there is one brim per object, one skirt per object, and the skirt distance if computed from the brim, then it can be wrong.
I'll have to rework this a lot more to have something reliable. Also, i have to create a proper test case.
i'll do that after the 2.7 merge

@supermerill Thanks for looking into this!
