LW-PLA travel and ooze
Test prints / LW-PLA: the foam is the calibration
Two towers with avoid-crossing-perimeters on: strings across the gap show travel and wipe, not retraction.
Toolpaths
Every extrusion move in the G-code, layer by layer. Drag the layer slider, scrub through the top layer, or play the print.
Toolpaths load when you open this view.
Read from the G-code that the printer gets. The clock adds each move at its programmed speed, without acceleration or travel, so it is shorter than the slicer's estimate.
Settings
On top of the stack that the print jobs load. The printer tuning page shows that stack.

Procedure
What it is for. LW-PLA oozes on travel moves, and the strings add mass and spoil the surface. Retraction barely works on LW-PLA, so this test compares the profile as it is with a wipe.
Print. Print both files on each printer: A with the profile as it is, B with wipe on.
Measure. Count the strings between the towers. Pull off the hair and weigh it.
Pass. No pass mark: the file with fewer strings and less hair is better. What helps is a shorter travel and a wipe, not a longer retraction. This matters most on the Kobra Max’s Bowden extruder.
Record. The number of strings and the mass of the hair, for A and B on each printer.
