Prints started to get all wonky about a week ago. I couldn’t figure out the problem. Changed the nozzle, tighten the belts, lubed the z screws, and cleaned the carbon fiber rods. Disassembled the extruder and I didn’t see any clogging, but when I disassembled the hall sensor, I noticed a lot of wear. Then I found a piece of metal inside the extruder that I suspect broke off from the hall sensor somehow. A new extruder arrived yesterday and the X1C is printing like a champ again.
3000hrs straight usage? That’s impressive.
I noticed that towards the last couple of hundred hours it started to clog/jam a lot more. I thought the gears might be wearing but it looked ok upon visual inspection. I wonder it’s an early warning sign. I only print PLA and PLA+ so nothing abrasive.
What are the replacement costs for this? I’ve heard that Bambu uses all proprietary parts so there’s no buying Chinese knockoffs at a discount.
That’s more than a year of work at a full-time job (2200 hours) for reference.
Are you trying a 3ed party extruder or going with the official replacement?
Official replacement. Already arrived and printing again.
I had the same basic experience with the hot end on my Prusa MK3S recently. Naturally it loves to kick the bucket anytime I’m making a gift for someone on it and not when I’m printing something unimportant.
Yeah, I need to have a bunch of spare parts available. Since Bambu’s warehouse is on the west coast, it takes a week to get to me on the east coast.
