The priming extrusions were handled separately from the rest of the wipe tower toolchanges. In order to be able to use the logic from previous commit for them (custom toolchange gcodes etc), some unpleasant code shuffling was needed
Each toolchange now emits:
- end filament custom gcode
- toolchange custom gcode; if not provided, a standard Tn command is inserted
- start filament gcode
Hopefully it is now consistent for SE/ME printers with/without the wipe tower
The priming line does not work - will be fixed in the next commit
- setting of the wipe tower parameters based od whether SE MM printer is selected is done in the WipeTowerPrusaMM constructor, so it does not distract in Print.cpp
- WipeTowerPrusaMM.cpp conditions checking for SE MM printer are now using a more descriptive const member variable, not the loading/unloading speeds (hopefully the functionality is the same)
The odd commands that lowered the speed override values for PVA, FLEX etc. were removed
Now the wipe tower backups user speed override, sets it to 100%, does what is needed
and restores the old value when finished. There are no special cases - lowering
the speed for certain materials can be achieved by lowering the volumetric flow.
at the firmware. The M220 B / M220 R are only applied for MM prints
without any flex or soluble (PVA, BVOH) material, as for these materials
the MMU slows down the print using the M220 code.
fixes "LCD Speed Modifier Lost on Tool Change #421"
Changes in SupportMaterial.cpp, TriangleMesh.cpp and 01_trianglemesh.t
are yet to be merged.
WIP: Refactoring of layer height editing.
Removed layer_height_ranges from PrintObject, as the Print/PrintObject
now hold their copies of Model/ModelObject.
