* The test print is designed to run with a high extruder flow rate,
but otherwise "normal" slicer settings. A high flow rate is obtained
by using a high printing speed (eg, 100mm/s) and a coarse layer
height (typically around 75% of the nozzle diameter). Other slicer
settings should be similar to their defaults (eg, perimeters of 2 or
3 layers, normal retraction amount). It can be useful to set the
external perimeter speed to be the same speed as the rest of the
print, but it is not a requirement.
