- rename stall*guard to StallGuard (match name with the vendor)
- separate TMC2130 module from EEPROM (they do not need to know about each other at all)
- separate SGTHRS settings from motion - moved to globals like all other "global" parameters
- improved EEPROM storage for SGTHRS
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.
- circular buffer can return its count of elements (even though a better solution may be implemeted later)
- stub_motion can handle multiple planned moves
- improved load/unload filament tests
While motion queuing is safe, code that relies on the current block
needs to run with the isr disabled.
Protect AbortPlannedMoves and CurPosition from isr' interference by
using a RAII guard.
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
Allow to chain moves by adding one extra parameter to the PlanMove[to]
functions: ending speed.
A move will always be accelerated from the last speed towards end ending
speed. The following:
PlanMove(100._mm, 50._mm_s, 50._mm_s);
PlanMove(200._mm, 100._mm_s);
Will first move the axis 100mm, accelerating towards 50mm/s, then
accelerate again to 100mm/s. The move will for then decelerate towards a
full stop after reaching 300mm in total.
Acceleration can be changed for each segment, so that a custom
acceleration curve can be created:
SetAcceleration(10._mm_s2);
PlanMove(100._mm, 50._mm_s, 50._mm_s);
SetAcceleration(100._mm_s2);
PlanMove(100._mm, 50._mm_s, 50._mm_s);
The ending speed might not always be reached, depending on the current
acceleration settings. The new function "Rate()" will return the ending
feedrate of the last move, if necessary.
AbortPlannedMoves accepts a new "halt" parameter to control how moves
will be chanined when interrupting the current move. By default
(halt=true) the move is completely interrupted.
When halt=false is requested, a subsequent move will be chained starting
at the currently aborted velocity. This allows to chain moves in reponse
to events, for example to accelerate the pulley without stopping as soon
as the FINDA is triggered, it's sufficient to interrupt the current move
followed by a new one:
PlanMove(maximum_loading_lenght, slow_feedrate);
... wait for PINDA trigger ...
AbortPlannedMoves(true);
PlanMove(bowden_lenght, fast_feedrate);
will seamlessy continue loading and transition to the fast feedrate.
Jerk control has been simplified. It now handles only the maximal
velocity change of the last segment, which doesn't require reverse
planning.
Add a new parameter "halt" (default to true) to control the stopping
behavior:
- halt=true: no subsequent moves will be planned, motions stops abruptly
- half=false: a new move will be chained after the current one
Extracted from the previous FW, may need some tuning based on units selected
for each of these axes (degrees, millimeters) - waiting for an update
of the motion implementation.
Updated starting conditions of the unit tests to reflect the global configuration.

This matches PulseGen::Position() and avoids confusion around the term
"current": Position() returns the head position in the queue, not the
"live" axis position.
We have PulseGen::CurPosition() now for this purpose, although we don't
expose it to Motion yet.
Implement Motion::SetEnabled (for symmetry with TMC2130::SetEnabled).
Rename DisableAxis to Disable and use the new SetEnabled. This makes the
member names more consistent.
- 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.
