Prusa MK3S Print Issues Due to Mechanical Instability

Confirm mechanical instability by performing the 'wiggle test' on the extruder carriage and print bed; any perceptible side-to-side play indicates loose components. Verify belt tension by checking if the belts are taut and produce a low-pitched bass sound when plucked, and inspect the extruder carriage and Z-axis rods for loose hardware or pulley set screws.
