These alerts summarize recurring failure patterns and the safest first checks. They are not recalls, and they do not replace official manufacturer notices.
mediumactive
AMS or multi-material feed interruption
What it looks like: Load/unload loops, filament stops before the toolhead, or repeated retry messages.
Check first
Inspect spool drag and filament path
Check PTFE couplers and buffer movement
Test the same filament without the feeder
highactive
Probe or Z-offset drift after maintenance
What it looks like: First layer suddenly becomes too high or too low after nozzle, hotend or bed work.
Check first
Re-home and rebuild the mesh
Verify probe mount and nozzle length
Set Z offset only after the machine is fully heated
highactive
Dual-Z or gantry synchronization error
What it looks like: One side of the first layer differs from the other or the gantry appears twisted.
Check first
Power off and mechanically level the gantry
Inspect both lead screws and couplers
Rebuild mesh after synchronization
mediumactive
Live-Z value no longer matches the sheet
What it looks like: A previously good first layer fails after changing build sheets or nozzle hardware.
Check first
Use the correct sheet profile
Repeat first-layer calibration
Inspect nozzle seating and probe height
mediumactive
Mesh compensation appears uneven
What it looks like: Some bed regions adhere while others remain too high or too low.
Check first
Inspect bed and carriage play
Heat soak before mesh creation
Confirm the mesh is enabled in the active profile
highactive
Dual-Z sides lose alignment
What it looks like: Gantry tilt, inconsistent layer height or one side of the bed prints differently.
Check first
Synchronize both Z sides
Inspect anti-backlash parts and couplers
Check frame squareness
highactive
Chamber temperature causes softening or heat creep
What it looks like: PLA jams or extrusion becomes inconsistent during enclosed printing.
Check first
Open or vent the chamber for PLA
Inspect hotend cooling airflow
Reduce ambient heat before changing flow
highactive
Repeated release-film separation failure
What it looks like: Supports remain on the plate while the model or layers stick to the vat film.
Check first
Inspect release film tension and clouding
Increase support contact appropriately
Verify lift distance, speed and exposure
