- fix homing procedure for Idler and Selector
(homing now ends with a move to the Parking position)
- fix unit tests' startup conditions with regard to necessary
homing of Idler and Selector
TODO: still test_cut_filament fails for minor reasons
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
Should also hopefully fix the random behavior of the DIR pins. When I was testing a really slow timing, the steppers seemed to want to not go in the right direction. That was fixed with the critical section. The 1us delay might be overkill, but I'm not the one that added a 100nF capacitor on the LATCH line (basically chip select). This might be part of the randomness that happened and why some board behaved better than others (stronger GPIO outputs)
- feed to finda engages the idler so no need to do that before
- retract from finda disengages the idler, again avoid double operation
LEDs set mostly by feed to finda and retract from finda
