Could a failing Synthetic Grease with PTFE (Super Lube 21030) cause the ELEGOO JUPITER SE to have symptom: Noise?

The high-frequency screech is typically caused by the stick-slip phenomenon on the Z-axis lead screw. A PTFE-infused synthetic grease restores the low-friction interface required to prevent harmonic resonance under the heavy load of the Jupiter's build plate. This is the primary maintenance requirement for large-scale resin printers to prevent mechanical binding.

Could a failing Z-Axis Lead Screw Nut cause the ELEGOO JUPITER SE to have symptom: Noise?

If the screeching persists after lubrication, the internal threads of the lead screw nut may have suffered galling or deformation. Replacing the nut ensures a precise tolerance fit with the lead screw, eliminating the mechanical play that allows vibration to amplify into audible noise.

Could a failing MGN15 Linear Rail Guide Block cause the ELEGOO JUPITER SE to have symptom: Noise?

The Jupiter SE utilizes linear rails for lateral stability. If the internal recirculating bearings within the guide block seize or lose lubrication, they will skid rather than roll, producing a piercing metallic screech. This part replacement restores smooth, silent travel along the vertical axis.
