Broken toolhead rear housing after update

[justin.shafer777]

Just updated the firmware last night and today I come back to the poop chute full and chucking piles everywhere. Found the chunk of the back toolhead on the build plate. Over 1700 hours of printing and this is new. Did something change with the update?

I dont know if it was an update, but it happened to me not to long ago. Right around 1800hrs.

Print Head Rear Cover

Lasr week my printer started to have unusual poops. Long and stringy, hanging up in the poop chute. Triggering the high level alarm. The next day I noticed the rear cover was breaking apart. So when the print head went to perform a perfect poop it wasn’t able to close the poop chute door. Thus the long and stringy poops. Here is a couple of pics. [20231106_165649] [20231106_153353] [20231106_165700] It took 4 days to get parts to the house. Good job Bambu Lab USA! It took about 10 minute…

Mine looks the same. I only print ABS, ASA, and PC. The thin plastic is just gone. I wonder if someone has made a model to print one out?

Got a video of it happening. HA

With this happening to more people as printers age there might be a printable version but for $5 I’d rather just add one too my next order as a spare.

Hi, I’ve had the X1C for a few days and read most of the threads with problems. To be aware when something similar appears.
For this problem, I can think of reinforcing the back wall of the cover with a piece of plastic or carbon? How long is it new? I don’t know how much space there is behind this piece. Will another 1-1.5mm insert fit? Of course I can take the cover apart and find out for myself. But it seems pointless to me if you already had it out there. I apologize for my English.
Thanks for the reply Fanda
Ahoj, mám X1C několik dní a pročítám většinu vláken s problémy. Abych měl povědomí až se něco podobného objeví.
U tohoto problému mě napadá, vyztužit zadní stěnu krytu plátkem plastu nebo karbonu ? Dokud je nové ? Nevím kolik prostoru je za tímto dílem. Vejde se další 1-1.5mm vložka ? Samozřejmě můžu kryt rozebrat a zjistit sám. Ale zdá se mi to zbytečné, pokud už jste to měli venku. Omlouvám se za mou angličtinu.
Díky za odpověd Fanda

Greetings Arachna, welcome to the forum.

I would not worry about this as it might only affect people who print 1000’s of hours at high temperatures.
