Check a cold hotend or heating fault without bypassing thermal protection.
Check a CR Touch or BLTouch-style probe that does not complete its startup movement.
Locate mechanical drag, loose motion parts or driver overheating behind sudden layer shifts.
Separate a nozzle restriction from heat-creep, spool drag and extruder-tension problems.
Treat a thermal-runaway stop as a safety fault and identify unstable sensing or heating.
Restore removable-media detection by checking format, capacity, filenames and card hardware.
