# Flexible filament (TPU, TPE): slower long moves for the lanes holding it.

# A poller checks the material of every lane (from Spoolman via AFC) every
|

# 5 s and sets the lane's long-move speed: flex_speed for a flexible
|

|
|
# material, the configured long_moves_speed again when the lane holds
|
||
|
|
# something else. Only changes are sent. SET_LONG_MOVE_SPEED is runtime
|

# only; after a Klipper restart the poller applies it again.

# AFC/AFC_Hardware.cfg, 25 mm/s) has no runtime command and is the same
|

|
|
# for every lane. The purge after the load is already slow (2.5 mm/s).
