My fairly new (less than 100 hours) had filament stuck in the extruder, I removed and cleared the blockage. Ever since I cannot print and get the ‘Cutter is stuck’ error message.
I have read through previous threads, but no luck in fixing as yet.
I’m 99.9% sure I have all the cables connected & seated properly.
The fan does spin briefly when switched on, and I can manually turn the fan on via the front panel, so I’m pretty sure the filament cable is connected and seated properly.
I cannot see how to access the rear of the cutter lever arm to check the magnet is in place, how can I do that?
I have ordered a spare sensor cable just in case, but likely not here for a week.
Remove the front cover and you can better see the entire cutter assembly.
I added some text to pictures. Even though the page is a year old, if you have a P1S it is 100% accurate still. That just the page revision date.
With the front cover off, push the cutter lever inward and you should see the Cutter Blade move into and out of filament path through the extruder.
The cutter lever is spring loaded and SHOULD spring back on it’s own which should pull the cutter blade out of the filament path.
Make sure the cutter blade is attached th the cutter lever and that the lever/blade assembly is free to spring back when you release from pushing it.
The magnet, if missing, has activated the switch but absent the magnet, it can not deactivate the switch.
Do you have a set of metric hex drivers in 1.5mm, 2.0mm, 2.5mm. You absolutely will need those hex drivers to work on printer.
In last picture, the actual cutter blade has arrows pointed at it. This fault is indicating this blade is stuck pushed in. The magnet activates/deactivates switch upper arrow is pointing to.
See if this helps.
The video shows how the lever and cutter work together.
Make sure the cutter blade is attached to the lever as shown in video. It should slide back and forth easily. Do not completely remove the screw that holds the lever. Just back it out several turns and the lever should be free to drop and blade should come completely out of the filament path.
I have had this same problem for months and it kept getting worse. Bambu sent me a new filament sensor, which made the problem slightly better temporarily. Now, I cannot print at all. I have disconnected and reconnected all cables on both circuit boards in the toolhead. This helped a little previously, but no longer. All cables are plugged into their sockets properly and the magnet in the cutter handle is present. Could the new sensor be defective? has anyone solved this problem by replacing the extruder interface board or the toolhead circuit board? I have not yet taken the back off the printer to reseat the cable going to the toolhead - would that be worthwhile? Thanks!
Hello, I also have the same issue with my printer. It kept saying “cutter stuck” for days, but somehow it can print again after a few week’s leave unused. However, it only prints for 10 mins or so before the “cutter stuck” error shown again …
I’m pretty sure that my cutter isn’t stuck, and i tear down the extruder, cutter and Hall Board(which i also changed a new one) and reconnect all cables, but it just didn’t went right. I think that it works SOMETIMES can proof theres nothing wrong with my wiring and hardwares.
Has anyone here resolved this? I have the same issue with my X1C where it will print for a bit until it gets hot, then the “cutter is stuck” error shows up. It’s not even trying to cut the filament, it just pops up in the middle of a print. Letting the nozzle cool back down causes it to start working again until the next failure. I’ve replaced the cutter blade and the sensor board to no avail.
