From 98fea2f6ee64f8f4e0456bcd528208118a2fa65c Mon Sep 17 00:00:00 2001 From: Lukas Matena Date: Fri, 6 Jan 2023 13:25:42 +0100 Subject: [PATCH] Wipe tower: use GCode::set_extruder, allow ooze prevention: this removes duplicated code and fixes toolchange retraction The ooze prevention part needs further work, now it does not work as advertised (the tall skirt) --- src/libslic3r/GCode.cpp | 49 +++++++++++-------------------- src/libslic3r/GCode/WipeTower.cpp | 5 ++-- src/libslic3r/Print.cpp | 6 ++-- tests/fff_print/test_multi.cpp | 24 +++++++-------- 4 files changed, 35 insertions(+), 49 deletions(-) diff --git a/src/libslic3r/GCode.cpp b/src/libslic3r/GCode.cpp index 13b21174a..7c786cf89 100644 --- a/src/libslic3r/GCode.cpp +++ b/src/libslic3r/GCode.cpp @@ -260,21 +260,10 @@ namespace Slic3r { } - // Process the end filament gcode. - std::string end_filament_gcode_str; - if (gcodegen.writer().extruder() != nullptr) { - // Process the custom end_filament_gcode in case of single_extruder_multi_material. - unsigned int old_extruder_id = gcodegen.writer().extruder()->id(); - const std::string& end_filament_gcode = gcodegen.config().end_filament_gcode.get_at(old_extruder_id); - if (gcodegen.writer().extruder() != nullptr && !end_filament_gcode.empty()) { - end_filament_gcode_str = gcodegen.placeholder_parser_process("end_filament_gcode", end_filament_gcode, old_extruder_id); - check_add_eol(end_filament_gcode_str); - } - } // Process the custom toolchange_gcode.
