From e3a583292ad480e61ddf5815f50cbfb671c02e7d Mon Sep 17 00:00:00 2001 From: tamasmeszaros Date: Mon, 2 Mar 2020 12:43:00 +0100 Subject: [PATCH] Promote max_bridges_on_pillar to be a runtime parameter. This way the user greater control over support tree branching and the amount of pillars created. --- src/libslic3r/PrintConfig.cpp | 10 ++++++++++ src/libslic3r/PrintConfig.hpp | 4 ++++ src/libslic3r/SLA/SupportTree.cpp | 1 - src/libslic3r/SLA/SupportTree.hpp | 4 +++- src/libslic3r/SLAPrint.cpp | 3 +++ src/slic3r/GUI/ConfigManipulation.cpp | 1 + src/slic3r/GUI/Preset.cpp | 1 + src/slic3r/GUI/Tab.cpp | 2 ++ 8 files changed, 24 insertions(+), 2 deletions(-) diff --git a/src/libslic3r/PrintConfig.cpp b/src/libslic3r/PrintConfig.cpp index 2be1f8cf6..adb1f4ee3 100644 --- a/src/libslic3r/PrintConfig.cpp +++ b/src/libslic3r/PrintConfig.cpp @@ -2653,6 +2653,16 @@ void PrintConfigDef::init_sla_params() def->max = 15; def->mode = comSimple; def->set_default_value(new ConfigOptionFloat(1.0)); + + def = this->add("support_max_bridges_on_pillar", coInt); + def->label = L("Max bridges on a pillar"); + def->tooltip = L( + "Maximum number of bridges that can be placed on a pillar.
