I am having issues with my printer not loading the filament. The error message was “Please remove the external filament from the extruder. If an AMS is to be used later, please connect the PTFE tube to the coupler and click the “retry” button. [07FF 8003 175352]”
I checked and removed my AMS, no clogs there. I removed and replaced the hot end. I also ran filament through the extruder, and it came out on the other side with no issues. I am trying to get it to load filament from a spool off the back just to get it to load. I even blew out the entire thing with compressed air.
I think it’s an issue with the extruder, and it not sensing the filament. When I hit the load button, the gear isn’t turning, and it’s not doing anything, and it keeps telling me the same thing, retry.
I don’t want to replace the extruder unless I know that’s it. I can’t find anything online with someone who has the same issue. What can it be?
I’ve seen posts from people who accidentally severed the ribbon cable that wraps around the extruder when trying to use a tool to manipulate the plastic ring holding in the PTFE tube… this ribbon cable is connected to the toolhead board from the filament runout sensor on the extruder… check the cable seating and if the cable is intact?
I’ll check that. When I looked at a video on how to install a new extruder I noticed my extruder ribbon looked a little different than the one in the video. I’ll check that.
I am having the same issue. My X-1 C is three weeks old. I disconnected and unplugged the AMS and still displays the same message, so I don’t think it is the AMS. I removed the Boden tube from the Extruder, which all looks clear.
Is there a filament switch in the Extruder that could have gotten stuck?
Does anyone have a suggestion?
I am getting this same message. But I’m trying to print from the AMS. I can print without any problems with a spool on the back and not using the AMS, but when I try to print with the AMS I get this message. I’ve checked every PTFE tube and there is NO broken filament blocking any pathway.
Same issue. AMS has been connected all along and I’ve never used external. I did remove and reconnect the PTFE coupler but had a successful print after that.
I’m having the same problem too. What ended up being the solution? I’ve ordered a new extruder, hoping replacing the holl sensor will fix it? It’s even worse with the ams on there!!
This just started happening to me as well and no matter what I can’t get passed the error. I’ve cleared every tube and checked the hub, all looks good. The machine’s error is telling me the filament tube is blocked (it isn’t) and the response code in Studio is that I need to use the AMS (I am).
What’s the use of this form when somebody post that they got a solution but they don’t tell you what the solution is and they’ve been asked several times I have this problem too and I’m trying to figure out what’s wrong it’s no big secret to share the solution
Hey folks, if this is what I thought it was, you don’t need a new extruder, nor a new filament sensor, since the problem is a design flaw! It turned out that there’s a little lever the filament pushes off to the side as it enters the extruder head, and that lever acts as a switch to detect whether there is filament in the extruder or not. Due to the mechanical design, this lever can get hung up on a ledge and stuck in the deflected position, causing the printer to think there’s filament present when there’s not. You can temporarily solve this by taking it apart, and permanently solve this by shaving off a bit of plastic to eliminate the flat surface the lever can get hung up on. A warning that taking that part apart is delicate, and putting it back together is a PITA because you have tiny spring-loaded lubricated parts that need to be wrestled into place at the same time. Below are some photos showing the major steps - the 3rd is exactly where I shaved off some plastic to permanently fix the problem.
I have never had the problem again since doing this. However, I suspect that if you don’t do everything described above, but just firmly flick the spring-loaded manifold just below the Bowden tube connectors, in the X-axis direction (so towards the back of the printer if you’re looking head-on at the extruder), it will hopefully shake that lever loose so it can reset and stop falsely detecting filament present. If you look down into where the filament feeds, you should be able to see a shiny metal thing in the way of where the filament needs to go. If you don’t, it may still be stuck off to the side.
I made two YouTube videos, one shows a quick full assessment of the extruder head to diagnose potential filament pathway problems, and the second shows the full detail of the modification/fix that I made to keep this problem ever happening again.

By the way, note that if this is in fact your problem, doing a warranty replacement of the filament sensor will not solve the problem because that component doesn’t include the lever mechanism. You would need to replace the buffer and hope the replacement has this design flaw fixed.
