Newly each custom G-code block may exchange the following values with slicer:
Position and Z-hop:
position (read/write)- 3 element vector (X, Y, Z) of current G-code position. Z element contains the current Z hop.
zhop (read only)- initial zhop value
Extruders: vector variables, one element per extruder:
e_position (read/write) - absolute E position, only available with absolute extruder addressing
e_retracted (read/write) - current retraction state
e_restart_extra (read/write) - current planned extra deretraction when starting printing
For readibility, script's if / elsif / else / endif syntax was modified:
{if cond then
block
elsif cond then
block
else
block
endif}
Semicolon is not required after else or endif.
The wxString saga continues. wxWidgets 3.0 don't have the wxString::FromUTF8(const std::string&) overload, we must use the GUI::from_u8 helper
Also wxWidgets 3.0 don't allow to disable wxString->const char* conversion, so calling show_info(wxWindow*, wxString, const char*) was ambiguous
Several includes moved around
Refactoring of GCode export of color changes, extruder switches etc,
so that the "color change" like extruder switches are applied first
at the Wipe Tower / G-code export, so that adding / removing
an extruder switch at the G-code preview slider does not invalidate
slicing.
