I am looking through Bambu’s spare parts for the X1C. They show a dual LED Lidar assembly. As for the associated Circuit board, they only show a PCB for the single LED Lidar.
I had gotten on the Asian Babmu site by mistake before. That site had both the dual LIDAR assembly and DUAL PCB. They also had the parts I really wanted that are out of stock in the USA (Grrrrrrr). I really wanted a new filament sensor assembly, so I was grabbing other items to make a minimal of $50 to save shipping. I really couldn’t find much.
I was then thinking (I have a lot of spare parts in stock) I do not have a lidar assembly, if ever needed. Now I don’t know what my X1C has. It is an early unit from this time last year (that may have been 2022 - time flies). I would assume I have the single LED LIDAR assembly. They do not sell that, only the DUAL, but do not have the PCB needed for the dual.
