These methods allow travel moves to be made without checking the distance against XYZ_EPSILON, which may prevent the move from being emitted. This is useful when we want an important comment to be emitted, like a layer change.
get_travel_to_gcode() functions don't maintain m_pos, which later causes incorrect speed calculations as the movement vector is measured incorrectly.
Ensure that client code can't make moves without maintaining m_pos.
This fixed duplicity M106, which doesn't have any effect.
Also, it was implemented hysteresis that filters out small back-and-forth changes in fan speeds.
Previously there was an algirithm that was fitting a curve through
the resulting seam points. This worked for smooth models, but was
failing for some very basic cases (such as a cylinder).
The new algorithm builds on the previously implemented visibility
algirithm but does not do the curve fitting anymore.
Now the code is more separated for the four seam placement
options (rear, random, aligned, nearest).
Nearest and random are handled as one would expect.
Aligned is handled in a more "brute force" manner
(trying multiple seams and picking the best one)
and rear smartly switches between two modes
(center straight line projection and max y).
* Fixes SPE-2116. The reason for this bug was forgotten change in
WipeTowerIntegration after change in gcode.cpp.
* Prevents future similar bugs by unifing the functionality to a method.
Ignore the first intersection of the travel path with the object from which the travel starts.
Created a new class TravelObstacleTracker, for wrapping all data structures related to lift before obstacles.
During layer change, instead of generating the gcode, generate a placeholder tag. Then at the end of layer processing replace this tag with a ramping travel move.
This solves the issue, that one does not know the starting point of the current layer where the layer change gcode would be originally generate.
The ramping layer changes uses smoothing of the ramping travel. Also it is adjusted in such a way that it increases the ramp angle when the travel is too short, to always reach the next layer.
