2.5 hours of melted filament curled back up and around to the top of the heater, completely encased the lower nozzle and heater, wiring also encased in filament. Unable to access any screw for removal.
If anyone has any suggestions.
Support ticket submitted over a week ago with no response. I guess the recall has taken top priority and this will be returned for a refund.
Heat the nozzle and use tweezers to remove the filament, it sucks, but just about the only option.
You might need to enable the Maintenance mode in the settings, this will disable the abnormal heating popup and keep the heater on even if it detects the nozzle is gone or something else is wrong. (Don’t leave the printer alone while this is enabled)
Hello,
The problem is not leaving the machine alone, it is that not even the camera in the cell phone app works well and you are monitoring it to be able to stop it if you see something that does not fit with a good impression.
I had this issue as well. I took my soldering iron and tweezers to start peeling it away. Unfortunately it had gotten all over the thermistor wires and they were toast. I ended up having to replace the thermistor. I also ended up having to replace the TH board, but I think that’s just because I plugged in my thermistor too aggressively. I heard a snap when installing it and then it would not stay seated.
I had the same issue and needed to replace the hotend heating assembly because of the thermistor wires damage… they are too exposed and are so fragile. Bambu should review this design and provide a safe conditions to.
I had the same issue as described in this thread (only about 10 min of printing) but now I am getting a “Nozzle temperature malfunction” It told me that I need to make sure the connector in the back was plugged in at it is so I think I will need to also get a new hotend heating assembly.
It is possible to replace just the heating element and thermoster with proper cables - it is cheaper than the complete assembly.
