# Description
Fix application freeze when Prime Tower brim is set to Auto
This PR fixes an issue where enabling Auto brim width for the Prime Tower caused the application to freeze and consume unbounded amounts of memory.
Root cause
0c5f6c9865/src/libslic3r/GCode/WipeTower2.cpp (L2036-L2039)
When Auto brim is selected, the brim width was not being computed and the raw configuration value (-1) was used directly.
This resulted in an effectively infinite loop during Prime Tower brim generation, leading to runaway memory allocation instead of a controlled failure or a crash.
Solution
The Auto brim width is now properly computed based on the Prime Tower height, matching the intended behavior and existing logic used in other slicer implementations.
* Enhance GCode handling for Z-axis movements
- Updated `travel_to_z` method to include a `force` parameter, allowing forced Z movements.
- Modified GCode generation logic to ensure Z position is restored after unknown last positions.
- Enforce z restoreation after tool changer
* Improve filament_multitool_ramming logic
* fix indent
and modify the path of travel to the wipe_tower after flushing
