Detailed Description

Feed filament to Bondtech gears of the printer.

Continuously feed filament until the printer detects the filament in its filament sensor. Then it feeds a bit more very gently to push the filament into the nozzle Disengages the Idler after finishing the feed. Disables the Pulley axis after disengaging the idler.

If filament has been successfully fed into the fsensor, records/updates PTFE length. To prevent constant EEPROM updates only significant changes are recorded.

Member Function Documentation

GoToPushToNozzle()

void logic::FeedToBondtech::GoToPushToNozzle

(

)

Transition to PushingFilamentIntoNozzle. Allows jumping into the state machine from outside just to push filament slowly into the nozzle (this principle uses tool change)

State()

uint8_t logic::FeedToBondtech::State ( ) const

inline

This method may be used to check the result of the automaton

Returns

OK if everything went OK and printer's filament sensor triggered

Failed if the maximum feed length has been reached without the the printer's fsensor trigger being reported

Step()

bool logic::FeedToBondtech::Step

(

)

Returns

true if the state machine finished its job, false otherwise
