- bdpressure_check.py accepted only extension version 1. The sensor now runs firmware version 2 (bytes 54-65 unchanged, diagnostics added), so every purge check reported bd_pressure as not answering. Accept 1 and 2. - _LOAD_FOR_CHAMBER: the Blobifier only purges with the QGL applied, so the load before the chamber soak skipped its purge (0.0 mm extruded). Level the gantry and home Z first when the QGL is not applied. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
