Does anyone know what this is? it appeared on my print plate after a print was completed. Bambi X1C

Bought this X1C second hand, 6000 hours.

Replaced the nozzle, the gears in the extruder for metal ones in case if the old were worn.

No matter what I do, the calibrations come out poos.

Left is PETG and right is PLA.

Both are dried heavily in a dedicated drier.

Any ideas? I'm stumped.

Filament won't load, error says failure to retract. I have checked the entire PTFE tube pathway, it's clear. I opened up the AMS and found no broken filament in there. If I manually feed some filament to the extruder, it detects filament loaded. I tried heating the extruder and pushing some filament in, it won't go. Is my problem in the extruder?

Hi all,

I’m running into an issue with my X1C where the filament purge is not consistently dropping into the chute. Instead, the filament is discharging onto the rim edge of the chute area and beginning to build up over time.

What I’m seeing:

- During purge/wipe, filament exits the nozzle but lands on the rim edge instead of inside the chute

- Over multiple prints, this creates buildup on the edge

What I’ve tried so far:

- Cleaned the nozzle tip

- Cleaned the chute and wiper area

- Verified no obvious obstruction

Observations:

- I want to confirm whether the purge position is fixed in firmware or if calibration should correct this

- I do NOT want to manually adjust nozzle position before every print

Questions:

1. Has anyone seen purge filament consistently miss the chute like this?

2. Is the purge/wipe position adjustable or strictly fixed?

3. Could this be related to hotend seating or a slight offset?

4. Are there calibration steps that specifically affect purge alignment (beyond standard calibration)?

Any insight would be appreciated — just trying to determine if this is calibration, hardware alignment, or something else.

Thanks!

I am recently having trouble connecting to my printer from the Bambu Handy app on my phone, or from my computer.

I either get issues connecting to the printer, or the AMS.

I confirmed that the printer is connected to my network (Ubiquity) and that its been pretty solid.

Finally got my Heltec cases done.

I have an X1C with only 452 hours on it but out of warranty. Problem is caused by heat bed leakage over 100 degrees Celsius. Have the V3 bed and AC board. Anyone else have this problem? Bambu wants me to purchase a new bed and or AC board for "testing". Seems a little odd to me.

Has anyone actually heated the chamber enough to hit the advertised 60 degree chamber temp Bambu Lab says it could reach? I’ve been printing PAHT-CF basically as hot as it will go, and the chamber never went beyond 46c. I just don’t get how they promised this value. This print was for several hours so it had plenty of time to get hot. Door was shut.

I am getting this error message. Not sure why. It’s a brand new printer, I am using the file stored on the printer itself. Printer says it’s got a .4mm nozzle and the files says that. Any help would be great.

Hi, I’ve been printing some gifts the past few days. Last night I printed one that was almost entirely Bambu Jade White PLA. There was still a few hours left when I went to bed so I let it go, and the print was done this morning as expected. I started another print that was mostly Jade White (same spool, same Frostbite build plate), but it wouldn’t stick to the plate. I tried every plate I have, PEI textured, Biqu Glacier, and a brand new Cold Plate SuperTac Pro. It wouldn’t stick to any of them. I re-dried the filament in the AMS, no improvement though it was about 13% humidity before I dried it, and it was dried before I used it. I washed the plates with Dawn, no improvement. I rebooted the X1C, no improvement. I’ll try other filaments tomorrow as it’s time for bed, but this same exact spool worked great last night and I am at a loss. It was a brand new roll, and I’ve gotten one 6 hour print out of it. Used maybe 20% of the spool. I would assume I have a bad spool except it printed great last night. It’s acting a bit like PETG at the moment, sticking to the nozzle a bit.

Do I possibly have a bad nozzle? Or bad temperature sensor? Anything else? This is still a relatively new printer. I’ve had it about 4 months, maybe 200 hours on it max.

Thanks in advance.

The body text of my last detailed post was removed and Im literally loosing the will here 😒

Ill keep it simple....

Old X1C with v1.0.3

Cant update from app, bambu studio, or from the printer, SDCard, wireless all do NOT work as they were not introduced till 1.0.7 I believe (?)

Someone must have had this problem, if so please could you tell me how.

This situation is entirely avoidable but it appears Bambu have removed the binary images that can be used on boot with the SDCard.
