the amount of total extruded material and per extruder extruded material
up to the point the value is evaluated:
"extruded_volume", "extruded_weight",
"extruded_volume_total", "extruded_weight_total"
The previous method worked just for near collinear edges. But it was also used for sharp corners, and for those sharp corners, there was an overflow in the computation of weighted width.
Also, the computation of deviation error was wrong for those sharp corners.
Boost Voronoi diagram produced degenerated Voronoi diagram. This Voronoi diagram was detected by our method for detection of those types of degeneration. But rotation by PI / 6 wasn't able to fix it.
So now, when the Voronoi diagram is still degenerated after the first rotation, then we try another rotation by different angles to fix the degenerated Voronoi diagram.
and efficiency.
Also added an experiment of adding one more "ensuring" layer to support
top / bottom surfaces, disabled with one_more_layer_below_top_bottom_surfaces
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.
{if condition then block elsif}
The "then" keyword is now mandatory.
On the other hand, "then" keyword must NOT be used using old syntax:
{if condition}...{endif}
{if cond1}{expr1}{elsif cond2}{expr2}{else}{expr3}{endif}
could be written as
{if cond1;expr1;elsif cond2;expr2;else;expr3;endif}
the first semicolon after else is not manadtory, thus the following is valid
{if cond1;expr1;elsif cond2;expr2;else expr3;endif}
each expression could be also empty or contain multiple expressions:
{if cond1;elsif cond2;else endif}
