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)
Load filament performs feed to FINDA and retract:
- engage idler
- feed normal to FINDA with config::feedToFinda distance until FINDA triggers
- retract normal and as soon FINDA un-triggers move back to PTFE config::cuttingEdgeToFindaMidpoint
- disengage the idler
That implied introducing another substate machine - RetractFromFinda, which does the opposite
of FeedToFinda while also checking for the FINDA switching off while retracting filament.
Still, ToolChange and CutFilament need fixing with this change
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.
- Remove the combined PlanMove(a,b,c,rate) call. If we allow the units
of the various motors to be changed at compile time, the unit of
rate can vary between axes.
- Build PlanMove on top of the absolute PlanMoveTo.
- Add required stubs for TMC2130.
- Allow each axis mode to be set independently, since we have this
feature for free anyway.
- Rework internals to use PulseGen data types and structs.
