Yes: Hardened Steel Extruder Unit - X1 Series
$44.99 USD
It’s listed under accessories.
Went through the site twice, brain fart time right there, thanks for the help
I forgot to ask this earlier, unlike previously, the tube on the top of the toolhead will not release. How would I go about getting that to go without forcing anything? I have removed it, I believe, 4 times previously so I do know where to push but this time it is just not moving.
The end of my ptfe tube had swollen a bit and was hard to remove just by pushing by hand until I printed this which made it a lot easier
Thanks , I’ll put that on the list, I did finally get the tube removed but it was a significant issue. Hopefully it reassembles easily
Got everything back assembled and now I am getting the “failed to feed filament into the toolhead” error. I am watching the AMS push filament all the way through the tubes and it is getting to the toolhead with no problems . I also took off the tube and it is feeding the filament right out of the end of the tube so I don’t believe the tube is the issue. Perhaps I did not reassemble the extruder correctly but I have done it three times before without this issue coming up. Bambu did finally get to my ticket so we will see what they say but if anyone has ideas I am all ears.
Thanks
Usually when that happens is because the filament sensor lever is stuck. I would also check the filament sensor connector is fitted correctly
Looks like there was a small clog in there as well, now the unit is recognizing filament is in there but still not extruding it. I remove the tube, heat the hot end up and put a piece of filament in manually, hit the extrude button twice and it moves down but then anything after that the unit just clicks repeatedly. I tried a print and it went through the entire process and started printing but no filament was getting deposited. Surprised there is not a sensor for that.
I am attempting to post the video of this I sent to Bambu but it seems t hat it is not able to upload onto here.
Maybe your nozzle is clogged, also, you had issues with your cutter arm, is the cutter working correctly, maybe the cutter blade is blocking the filament.
Cutter is now G2G. Good idea on the nozzle, I do have a couple spares. I’ll do a swap and see what happens. Leading contender to me at least, is some sort of stripped extruder gear even though I inspected them during reassembly.
To verify the extruder can push filament through it, before installing to the printer, hold in the orientation that it would be installed, put a piece of filament into the top of the extruder and spin the yellow gear clockwise with your finger and the filament should come out of the bottom of the extruder. Spin the gear the other way to back the filament out. The screw going into the side of the extruder with the spring is the tensioner, I have always had mine fully tight, if that were loose it might not be able to push the filament to the nozzle.

Follow the unclog procedure on the wiki, using an Allen key heated up to remove the filament from the top of the hotend. Also check the heater and thermistor plug is actually in the connector properly. There’s no error for that either, it just won’t heat up.
I’ll try that, it is getting to the 220c I set it at, at least according to the display

If you need to get medieval with it, these uncloggers look like they will provide a lot more persuasion than an accupuncture needle:
Those are designed to be pushed through the extruder not from the nozzle up, like the needle is. They won’t work on X1C/P1 unless you remove the hotend, as it won’t push past the extruder gears. On the Prusa they show in the picture you can remove one screw and the extruder idler gear pivots out the way.

Thanks for pointing that out.
Do the BBL nozzles have any kind of coating on them to increase heat conduction or lubricity or anything else? Or are the hardened steel noozles just hardened steel and nothing more? If there’s a coating, I’m guessing it might get severely damaged by the unclogger, leading to a need to replace the nozzle/hotend soon after. If that’s the case, then I guess just save time and frustration by moving directly ahead with the replacement and skip the unclogger. Maybe a wooden toothpick would be a better tool if working from that same direction, as it would be less likely to cause severe damage.
I don’t know if they have any coating on them. I doubt if they do, or they would be advertised as such.
The method in the wiki using a small allen key heated up and pushed into the top of the hotend and then drawing out once cooled works well to remove clogged filament. It requires you to undo the 2 retaining bolts so you have room to put the tool in.
I find I get most clogs after running added filaments e.g. CF, glow, wood, so I make a point of running some cleaning filament through before going back to PLA or PETG.

By that do you mean a filament whose sole purpose is to clean, not to print, or do you mean a filament of the same type but without the junk (glow powder, CF, wood, etc) in it?
This is the one I use. It lasts for ages, I think I’ve only used about 1/4 of the roll in 4 years. You only need to draw through enough until it comes out clean.
