Hello, I am a new user on Bambu but I have some experience with other printers.
I’ve had the X1 Carbon for two days. And I’ve had the same problem twice.
The filament is jammed in the extruder just before entering the head. It was impossible to load or unload it without completely disassembling the extruder. In bambu studio I chose generic PLA.
My failure looked very similar to the photo posted on the wiki (extruder clog) the filament was bent and flattened.
On the wiki you wrote that the distortion is caused by too high temperature, but how to get rid of this problem?
The other problem is that the printer does not detect this case and continues to print in the air.
I printed at a temperature of 220C, will changing to 190C solve the problem? The same problem happened to me twice. Is there anything else I should change?
The best thing to do here is lower the chamber temperature. Don’t lower the nozzle temperature, instead open the door or take off/prop up the top lid. What is happening is that the filament is sofending in the PTFE tube before the print head and when it is pushed into the nozzle by the extruder it budges and clogs.
Have you printed a temp tower for your filament? Bambu printers often require a higher nozzle temperature than what is spec’d on the filament because of how fast the printer runs.
Too low of nozzle temperature can cause issues as the printer really has a harder time pushing the filament out of the nozzle. This puts a lot of pressure on the filament between the extruder and nozzle and can cause it to budge.
Just out of curiosity, what slicer are you using?
Both Bambu Studio and Orca Slicer have a Calibration section, that allows you to calibrate filaments.
For any kind of PLA I try to keep chamber temps from going above 40-42C. That’s the third metric from the top on the left in your temperature/axis tab of the touch screen. Any higher and you run the risk of heat creep causing this kind of jam. I have the AMS and nowhere to put it besides the top so I wedge the glass open with a couple scraps from my old printer when printing with PLA in addition to keeping the door open, that way the part fan in the tool head has better access to cool air and I don’t have to constantly pull the glass top off. Also just an unrelated personal suggestion I put a dab of clear ptfe super lube on the top of the tube running to the extruder because mine was making a high pitch squeal as it rubbed the bottom of the glass.
Also when you get into carbon fiber infused filament, its going to heat creep easier because carbon fiber has higher thermal conductivity so you have to be even more diligent with chamber and nozzle temps with CF filaments,
Thanks for the detailed description, you were right. Previously, the temperature inside reached 45C, now after opening the window it is around 33C. This actually seems to solve the problem. It’s a pity because the printer is much louder but it works
you can get the anti vibration feet from the store for the x1, I just got mine installed today and even with the door open they dropped the noise resonating from the table by ~20%. even more with the chamber sealed for ABS.
but it works
