Micro lidar camera malfunctioning on x1c

I have the problem that the Lidar module triggers a timeout. I have never had this error for about 8 months of owning the printer. Maybe the connectors on the print head board are not correct. I will check this after printing. Why a USB-C cable inside the printer would break is beyond me. Something like that never breaks. Unless the cables are of reject quality (so that they break off due to vibrations) or burn away somewhere due to excessive currents (I can’t and don’t want to imagine that).

I notice recently lots of “Old” topics are being brought back up.

  • To clarify on OP, if and when an issue has been solved please update with a solution so no one is mislead along the way and ends up reading a post without checking the date of original posting.

With that said, I can affirm that the X1-C’s Micro Lidar doesn’t have the OP’s issue being widespread. This is actually the first instance I’ve seen regarding this issue with multiple users from a year ago now. I’ve yet to have any error message regarding lidars function on any of the X1C’s in my inventory (besides “Failed to read build plate” - remedy is re-setting placement of plate)

After regular use I’d suggest going over the inside & outs of the toolhead and the complete machine itself. Dealing with electronics, if anything is loose or barely connected and happens to make contact while powered will cause shorts or failures with anything.

Due to the sheer movement of these machines, I always advise to add silicone glue to whatever is plugged in and suffers from movement/vibrations. It doesn’t take much and the silicone glue doesn’t damage anything as it’s dielectric as well. I can’t tell you how many connections I’ve had semi-loose while performing a full machine PM (Preventative Maintenance) which could’ve resulted in future damages to electrical parts.

Best of Luck to everyone and make sure to check dates on these topics and refer to official bambu labs wiki page for updated support on these instances. Sometimes there’s remedies already in place and issues can be resolved much faster than posting here in the forums.

Happy Printing!

Oh dear…

Had a bit of a story with that. Few are affected but depending on where the issue sits, it can be arduous.

First the USB cable, which has a high likelyhood of being squished during assembly and is subject to some movement, then the Lidar replacement, then the TH board replacement…

In my case, something else blew just before the TH board replacement and I got a new printer on warranty. Overall, it took 5 months.

So make sure to check and document if there was any pre-existing damage on the USB cable.

This must not happen during assembly.

My printer is working again.

Mine after 5 days the Lidar sensor died! He turned off out of nowhere, always giving me error!I followed all the guides that indicated the error code but nothing! Quini is not just a coincidence.I have written to support with the hope that they will respond soon.
