This commit looks horribly complex, but the main idea is to have each of the logic::commands
report their terminal OK state in the same way. That allow for leveraging this very moment
to initiate the idle timeout.
Additionally, I wanted to hide the logic of idle mode detection, which resulted in moving the
top level logic from main.cpp into logic/idle_mode.cpp and a set of additional files to compile
in unit tests.
This PR brings the following improvements:
- unifies the error handling of TMC and Homing/Stallguard errors on all motorized modules (Idler, Selector, Pulley)
- now we distinguish between Homing and TMC errors + we have a separate handling of these two kinds into CommandBase unified for all motorized modules
- adds unit tests to verify the function
- fixes SetFINDAStateAndDebounce (didn't obey the press parameter before)
Solves an interesting tiny issue introduced in the previous commits.
When we start with the filament in selector, the corresponding LED
is set to ON. However, all of the logic state machines only operated
on the LED pair of the active slot -> the starting LED may have been
left ON in some edge cases.
Now, this is resolved by clearing all other LEDs except for the active
slot where appropriate.
Both movable components now perform homing sequences transparently
whenever the logic layer invalidates the homingValid flag.
That reflects the fact, that the user may have moved the Idler or Selector
while trying to resolve a HW issue with un/loading filament.
Basic rules:
- Idler gets rehomed immediately and then moves into the target slot position
- Selector rehomes once it is possible - i.e. when filament load state
is AtPulley - then it immediately and spontanneously executes the homing
sequence and then returns to the desired state
Motivation:
- resolve startup issues (EEPROM says we have filament, but FINDA is not triggered)
- resolve accidental moves of Idler and/or Selector while
digging out stuck filament from the unit
That includes:
- introduce pulley slow feedrate and fsensor-to-nozzle distance
in config necessary for slowly feeding the filament from fsensor into the nozzle.
(the constant is subject to extraction into some other config as it has to be used in the printer as well).
- update FeedToBondtech accordingly to perform a gentle push into the nozzle
after fsensor detects the filament + update its unit tests.
- slight cleanup of LoadFilament + fix its unit tests
- add FeedingToNozzle progress code, as it might be interesting
to inform the printer about this task in the future
- revert non-clean changes from RetractFromFinda - it should not disengage the idler
- revert incorrect + fix ToolChange
- clean-up UnloadFilament
Besides Unload Filament, which only operates on active slot, all other
top level state machines check the validity of the command's parameter.
If the parameter is out of range for available slots, they return
ErrorCode::INVALID_TOOL now.
