# Description A plate using one filament no longer reserves or draws a prime tower in the plater just because multiple filament slots are configured. The shared footprint estimate gated "no tower" on the purge volume being zero, but on non-Bambu printers with the shipped defaults that volume comes from the SEMM flush matrix, which reads every configured slot and stays nonzero even when only one filament is used — so the preview showed a tower the print could never contain. The estimate now decides from the filament count alone, with wrapping detection and smooth timelapse staying the only reasons a single-filament plate keeps a tower, matching `Print::has_wipe_tower()`. The gate also moved above the flush-volume scan so the lone-filament path no longer pays for it. No change to slicing output — toolpath generation already omitted the tower for a single used filament; this removes the phantom preview, placement reservation, and validation footprint. # Screenshots/Recordings/Graphs Before the fix: https://github.com/user-attachments/assets/c5b0ea61-127d-408e-bafe-f1f76c58b996 After the fix: https://github.com/user-attachments/assets/ac6632b3-5d44-4013-aca3-73f6cfd1139c ## Tests <!-- > Please describe the tests that you have conducted to verify the changes made in this PR. --> Added a shipped-defaults single-filament case to `tests/libslic3r/test_wipe_tower_estimate.cpp`: it estimates a 5.04 mm-deep tower before the fix and zero depth after. `[WipeTowerEstimate]` and the fff_print `[WipeTower]` suites pass. <!-- > A guide for users on how to download the artifacts from this PR. --> [How to Download Pull Requests Artifacts for Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
