Printer model: Bambu Lab X1 Carbon Slicer: Bambu Studio (latest version) Filament type: (PLA/PETG– issue happens even without printing)
Problem description:
When the Y-axis moves back and forward, I hear a rattling or clicking sound roughly in the middle of the movement. It seems to come from the left side. I suspect it could be related to a shaft, a bearing riding on the shaft, or possibly one of the idler pulleys.
I’ve already cleaned the carbon rods and the metal shafts thoroughly and applied a small amount of oil. The noise is still present. It gets worse when the toolhead is positioned center to left. When the toolhead is on the right side, the sound is minimal or not noticeable at all.
The noise happens even when the printer is not printing, just during Y-axis movement.
Turn off the printer and try isolating the sound while moving the toolhead by hand.
Actually, first turn off the printer and give it a complete cleaning and maintenance.
Your y-axis rods are filthy, so I assume everything else similarly neglected.
Hi
I had more or less the same noise on my x1 and think I have found the culprit when doing a service cleaning all the rods I noticed the right hand Y axis steel rod has slight movement back and forward which makes the same noise …I have only just found it so looking on how to tighten it up ? There is loads of stuff on the belts and pulleys (which o have done trying to find this noise ) but none on the actual rail having movement in !!!
My X1 started clicking after cleaning the carbon rods. The clicking seems very regular so I could see it being a bearing (think shopping cart with something in the wheel) or the belt to gear alignment and the teeth are making the noise. It also sounded like a belt was in high tension or something like that. I moved the head manually during the cleaning but the only direct adjustment was the tension screws. I paused the print, loosened the 4 screws tightened the left 2 facing the back top then bottom, then the right two top then bottom. The clicking reduced. I would guess from that it is something in the tension causing a slight misalingment with the belt to a tooth gear.
This is what helped mine. Take off the left panel. There is a metal cover plate that holds the big bearing slide to the y axis rod. I loosed each screw 1/2 turn. I also cleaned the rods and put bearing oil on them, very small amount and rub into the rods.
I experimented quite a bit and also checked every pulley. But the sound comes from the bearing slide.
My X1C clicks but it’s from the right side. On mine it’s the plastic flexi belt for the wires and filament tube getting pressed against a fitting inside the housing at about the same height as the flexi belt. But not quite aligned. It causes the flexi belt to slide off the fitting with a small click. There’s a fitting available on MW to stop that clicking but I never installed on to see if it works.
