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
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.
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.
MMU-58
- Distinguish among FINDA on/off failuje
- The same applies to newly introduced Filament sensor errors
- Add TMC init error
- Add a communication error ID - to be used on the printer
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.
