This always contains the actual print_z of the toolchange, while layer_z contains the print_z
of the print. The two differ in case that wipe tower without sparse layers is used.
Related to #3834.
When was set use_external_mp_once to true then after first calling the avoid crossing perimeters this flag was reset which cases that on the second call of the avoid crossing perimeters the travel move didn't process as external.
Reworked skirt generator to only generate skirt at non-empty layers
(layers that actually extruder object or support) and to respect minimum
layer height. Skirt generator stops at the first layer where those both
conditions cannot be met.
Fixes [Request] Add optional perimeter to raft #756
Fixes First support layer does not stick to bed #2101
New parameters raft_first_layer_density and raft_first_layer_expansion
to influence the 1st layer of raft or support.
Fixes Allow to disable raft under support structures. #3772
Fixes raft is larger than necessary #2568
Fixes Supports on the build plate should have a solid bottom interface for better adhesion #1165
Changed the 1st layer infill to rectilinear even for soluble materials.
Fixes first layer of support for multi filament support oddly spaced #1445
Fixes Full Soluble Materials interfacing into Models + Soluble material noise on Bed #684
When the avoid crossing perimeters was enabled, and the wipe was enabled, there were unnecessary travels in the opposite direction than the wipe travel.
fixing "percent first layer speed was not applied over autospeed." GH upstream Slic3r #2945
our GH issue First Layer Speed Percentage not applying (#5829)
The problem is that PrintObject support generator is only run when m_layers.size() > 1, so one-layer object will skip it.
It apparently never worked, after recent refactoring (probably 8bfc986) it started to crash in GCode generator.
This commit fixes the crash, but not the problem. The raft is still not generated (like in all versions since 2.0.0 at least).
above the solid infill. Should fix
first layer of vase (after bottom layers) is bulging (0.6nozzle, 0.4 layerhight) #3712
Adjust flow of the "second" layer in spiral vase mode #2795
The thread local storage variables for the random number generator
were replaced by an external context variable.
Thread local storage is a scarce resource.
1) The macro-processor sanitizes the source code line for invalid UTF-8
characters. Ideally these invalid characters would be replaced with ?,
they are just dropped as of now. Better than showing an empty string
when converting to wxString though.
2) G-code export collects full error message for 1st occurence of an error
for each custom G-code block.
3) The composite error message now displays the errors collected in 2).
4) The error window is now scaled bigger and the Slicer logo is smaller
if the text is to be rendered with monospaced font, as the monospaced
text will not be word wrapped.
Errors in the file output templates are reported in mono-spaced font,
so that the arrow character ^ is displayed at the right column
pointing to the offending spot.
In addition to an existing "layer_z" placeholder variable,
a new "max_layer_z" has been added to custom G-code sections accumulating
maximum of "layer_z" over the print. This value may be used for example
in the end G-code of a sequential print to lift the print head
up before travel over the whole print bed.
