Could a failing XY Belt Tensioner Assembly cause the CREALITY K1 MAX to have symptom: Shaking?

The belt tension determines the resonant frequency of the CoreXY gantry. If the factory tensioner bolts are not released or the springs are improperly seated, the gantry will exhibit abnormal harmonic feedback during the Input Shaper sweep, potentially causing the 'shaking' to exceed safety thresholds or fail to find a peak.

Could a failing XY Axis Synthetic Lubricant cause the CREALITY K1 MAX to have symptom: Shaking?

Linear rod friction directly impacts the damping ratio of the mechanical system. Insufficient lubrication causes stiction, which introduces high-frequency noise into the accelerometer data during the calibration phase, making the intended shaking phase appear more violent or erratic as the stepper motors struggle to maintain frequency.

Could a failing Toolhead Ribbon Cable cause the CREALITY K1 MAX to have symptom: Shaking?

The ribbon cable carries the data signal from the ADXL345 accelerometer to the mainboard. If the cable has internal fatigue or pinched wires from shipping, the 'shaking' motion of the calibration can cause intermittent signal loss, leading the firmware to increase oscillation amplitude in a failed attempt to capture a resonance reading.

What is the most likely root cause for a CREALITY K1 MAX with symptom: Shaking?

The belt tension determines the resonant frequency of the CoreXY gantry. If the factory tensioner bolts are not released or the springs are improperly seated, the gantry will exhibit abnormal harmonic feedback during the Input Shaper sweep, potentially causing the 'shaking' to exceed safety thresholds or fail to find a peak.

System Nominal

The 'shaking' behavior during Input Shaper Calibration is a documented phase of the printer's startup routine. It is a physical frequency sweep intended to excite the gantry so that the internal accelerometer can map vibrations and apply inverse-wave filters to eliminate 'ringing' or 'ghosting' at high speeds. The physics of forced harmonic oscillation require this physical vibration to identify the mechanical limits of the frame.
