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)
This solves a number of issues - if FINDA or FSensor failed,
the unload was never "complete" - filament was stuck in the selector
blocking it from normal operation.
Now, after all errors have been resolved, filament is explicitly FED
into FINDA and then RETRACTED to Pulley.
- 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
- 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.
