Update temperatures for red PLA
Update red PLA cooling settings

Increase min_print_speed (jams below 20mm/s).
Up slowdown_below_layer_time to avoid needing too much cooling
Tweak retraction settings for FF Creator Left

Reduce retraction speed (too fast affects the wipe which causes delamination)
Use negative retract_restart_extra (blobbing when restarting)
Forcibly specify all the extrusion width settings for 95% infill

Slic3r seems to space things too far apart when trying to extrude large infill
widths. Either that, or we have issues achieving the target infill width.
Bump skirt_height to 1 in 95% profile

0 skirt height causes slic3r to crash.
Don't tilt support material angle
Bump up the number of shells for 95% profile
Use 0.2 layer height for 95% profile
Add xy compensation setting (default to 0) in 95% profile
Use 6 perimeters for 20% infill

Thicker walls for increased strength
slic3r.ini update
Add natural PLA 2 profile

1kg reel of natural PLA from esun.
Add some new infill setting profiles
Update speed settings for 20% infill

Raise all the non-bridging/support speeds to 120mm/s, and use 300mm/s for
travel.
Up min_print_speed to 20
Use rectilinear solid infill pattern

It's faster and looks less broken when dealing with funky top-surface shapes.
Update fast 20% infill proflie
Drop fast 20%fill profile

It's redundant with the fast 20% infill profile.
Drop negative retract_extra_distance

It's causing holes
