//! @brief Unload sequence to optimize shape of the tip of the unloaded filament
//!
//! Ideas to minimize flash consumption of this code:
//!
//! Create const array of extrude and feed_rate on stack, call increment current_position, plan_buffer_line() and st_synchronize()
//! in loop iterating over array.
//!
//! Same as previous, but create array in PROGMEM and call PGM_read instructions in a loop.
