Bambu Lab A1 first layer not sticking
Restore first-layer adhesion by separating plate contamination, temperature, calibration and material problems.
3D Printers
Creality printer hotend is not heating
Check a cold hotend or heating fault without bypassing thermal protection.
3D Printers
Resin print not sticking to the build plate
Find out why a resin print remains on the release film or separates during the first layers.
3D Printers
Bambu Lab AMS slot does not detect filament
Find why an AMS slot stays empty after filament is inserted.
3D Printers
Bambu Lab nozzle temperature is abnormal
Diagnose an abnormal nozzle-temperature message without bypassing thermal protection.
3D Printers
Bambu Lab chamber camera is unavailable
Restore a missing or frozen chamber-camera feed by separating network, privacy and hardware causes.

Creality CR Touch probe fails to deploy
Check a CR Touch or BLTouch-style probe that does not complete its startup movement.
3D Printers
Creality printer shifts layers during a print
Locate mechanical drag, loose motion parts or driver overheating behind sudden layer shifts.
3D Printers
Creality extruder clicks and stops feeding
Separate a nozzle restriction from heat-creep, spool drag and extruder-tension problems.
3D Printers
Anycubic resin printer LCD screen stays black
Test whether a blank exposure screen is caused by the test image, cable, power or LCD module.
3D Printers
Anycubic Kobra auto leveling does not complete
Find the point where Kobra auto leveling stops, misses the bed or reports a sensor error.
3D Printers
Elegoo resin vat leaks around the release film
Contain a resin-vat leak and decide whether the film, frame or fasteners need replacement.
3D Printers
Elegoo Saturn print tears from supports
Correct support separation by balancing exposure, lift motion, orientation and support contact.
3D Printers
FDM printer produces severe under-extrusion
Trace thin walls and missing lines through filament supply, drive grip, temperature and nozzle flow.
3D Printers
FDM print has excessive stringing
Reduce strings without hiding wet filament, heat or travel-path problems behind extreme retraction.
3D Printers
3D printer reports thermal runaway
Treat a thermal-runaway stop as a safety fault and identify unstable sensing or heating.
3D Printers
3D printer does not recognize the SD card
Restore removable-media detection by checking format, capacity, filenames and card hardware.
