Bambu A1 PETG Stringing Fix

Fix Bambu A1 PETG stringing with a two-tower test before changing Bambu Studio retraction or flow dynamics. Separate wet PETG, hot profile, seam blobs, and PA issues.

Print the two-tower test and lower temperature 5 C.

Bambu A1 First Layer After Nozzle Change

Fix Bambu A1 first-layer problems after a nozzle change by checking installation, calibration, plate cleanliness, and the first-layer patch.

Run the five-patch first-layer test after washing the plate.
