Hello everyone. I have had my X1C for over a year and absolutely love it. I have over 2000 hours on it. Recently it developed a new noise at the start of a print. It homes itself fine. Then goes to the right side of the plate to read the calibration board, then when it moves to the front to read the plate i.d. it lets out a quick loud shreak. Almost like it is trying to move and something won’t let it. It lasts less than a second and then proceeds to move on to the bed leveling and prints fine.
It is consistent in both Bambu Studio and Orca Slicer. I have performed maintenance, run the self check and calibration sequences and it is still there.
I would appreciate if anyone has any ideas the would like to offer up.
Thanks!
Try replicating the noise by manually moving the toolhead using the touchscreen controls. Or do it with power off, simply moving the toolhead by hand. If you can feel a “bump”, there may be some debris on the belt. If you can not, maybe some idler needs lube.
A couple of months ago, I got four X1 carbons at once. One of them made a loud rattling almost a buzzing noise. Some kind of harmonic resonance I’d say. After extensive communication with support I was finally told to lubricate the Y-axis bearings with white lithium grease. I used the Bambu packet grease.
Since the only way to lube the bearings that run on the left and right metal rods, is to coat the metal rods, I pushed the head to the back and put a small glob of grease on the rod, in front of each bearing. Then ran it to the front and put a glob behind each bearing.
Then ran it forward and back a bit, and ran a test print.
So far so good. The noise seems to be gone.
I read that lithium grease dries out after 6 months or so, which could explain why these noises suddenly start happening after months of silent operation. And it would explain why one printer sitting in a warehouse for months longer than the other printers, would be noisy while the others are quiet.
Thanks for the reply. I have manually run the head through all the motions and no noise at all. I focused on the area by the plate id. Nothing. I have done full preventative maintenance on the machine twice now and no change. Cleaned and lubed all the rods and bearings, checked the belts for wear, performed the belt tension maintenance, I mean I did everything. The self test and calibration routines run and check out fine. I am totally stumped.
I guess it is time to reach out to bambu tech support but that is such a pain and response times are so slow.
I welcome any other ideas you may have.
Thanks
I have a video of the printer making the noise but can’t figure out how to upload it.
I figured it out! Followed Raz’s suggestion manually moving the tool head across the problem area. Finally got it to hang up. Turns out that the PTFE filament guide I printed off the bambu website was rotating around far enough to get agains part of the front panel causing it to snag. I removed it and am now printing a shorter one. Seems like bambu should be aware of this potential problem.
Hoping it hasn’t damaged the printer in any way. It seems to be printing fine. Fingers crossed.
Thanks Raz!

Glad you figured it out. Others have had similar issue with PTFE guides. They honestly seem to create more trouble than they solve.

I agree, I tried one and removed it the next day, too many issues for me. I’ve since printed an LED riser and now I have no reason at all to use one.
Hey guys, I literally just had the same exact thing happened to mine. It sounded like something broke inside at the start of the Print it was super loud. And now with movement from left to right, it is tapping and popping constantly causing horrible ghosting on my prints
