updated firmware on one of 2 x1c re calibrated it… it forced me to use new Bambu studio, I installed new studio, resliced file, Print time increased for the same file +45 minutes, I thought whatever and sent it… print completely failed, texture rough like a scotchbrite pad, sent to other printer which didn’t have new firmware, same thing happened. uninstalled studio and installed 1.10.01.5 and sent to non upgraded firmware printer (print time back to what it was originally) and file is printing fine. not sure what to do outside of downgrade on other printer and close the upgrade warnings constantly. anyone else have issues?
I just upgraded my firmware and studio and had the opposite result. faster and cleaner prints. I did recalibrate the printer after firmware update. Also I had just done routine maintaince as well (not that that should make a difference).
Until the 25th of March, I could print with any filament without any trouble. Then I had to accept the latest firmware, two new versions of Bambu Studio in a few days and now, I can’t print anything properly.
I first though that moisture had gotten to my filament. I tried with a new toll of PETG-HF (a matrial I was using just fine til then), and yes, I had thoroughly dried it in the X1C for 12 hours, with the right settings as defined by Bambu Lab. Still a disaster. It strings, it makes holes, it’s a disgrace.
Any advice for a desperate guy?
I had to roll back to previous firmware on printers (in handy app) and reinstall older version of bambu studio, prints just fine with the previous combo.
I figure the same things happen to me here. I did a ton of troubleshooting and calibration, and I nearly drove myself crazy over it.
Thanks for posting this to confirm my suspicion.
It happened to me as well. Twelve hours ago, out of nowhere, the 2nd/3rd layer looked terrible, and there was a loud noise/vibration from the nozzle colliding with the previous layer (1st). I stopped the print because I didn’t want to deal with any mechanical damage, and I have tried to troubleshoot ever since.
I will try to revert the firmware/studio and come back to confirm.
Here’s the printed part compare to the flow calibration sample (Sadly I have a ton of flow calibration).
Yup, it worked. I just downgraded the slicer to version v01.10.02.76, and it works!
Note: For this to work, I have to ditch the old 3mf file and start the new project file with a clean slate.
thanks to you both, Eric_M and ratchanonspk for pointing me to the right software. Although…
I guess I am not lucky. I’m still in the same situation.
backtracked the firmware.
backtracked Bambu Studio.
used a freshly dried roll of PETG-HF, a material that served me well so far. To dry it, I ran it in the printer’s drying routine for petg, setting the temp to 80°C for 12 hours.
cleaned up my 0.4 nozzle (purge, needle, metallic brush) and even added some repellent on it.
used a clean plate with glue on.
left the door opened during the prints as required.
Thank You!!! I will try.
I have had similar issues with the new firmware and new Bambu studio. Previously my X!C was working perfectly or near perfect. I already downgraded to the previous version 1 firmware, didn’t help either, from the Bambu Handy app. I will try reinstalling the version you suggested of Bambu studio. I did not compare print times so I can’t comment on that issue on my printer.
My issues have been the following…
I get globs of filament coming out of the nozzle on the first layer. Could be that the wipper is not working but one part on the front right of the bed lays down perfectly then when it prints the next part I get the 2 globs of fiilament Spits in the middle portion of the bed.
I got twice that the build plate could not be detected on whether it is installed correctly
One print will print near perfect and the next I will get the globs spits. Also other times I get the center part to print first layer perfect easy to remove and then if it prints the first layer correctly it will bond to the bed to hard and I have a hard time to remove the first layer which peals off the part when I try to remove it.
There maybe other issues I don’t remember. So I am hoping that your suggestion to go back to the previous Bambu Studio will get me up and running again. I wish they would test this stuff before makeing a new firmware public. I thought I heard somewhere that the AI was not working correctly.
Did you start a new project and not use the corrupted 3mf file?
If you have a G-code file from a previous good print, you can try it to rule out the issue caused by the slicer.
Hope it works for you.
I went and picked up several 3mf’s from MakerWorld. BS took them normally, but either the filament starts stringing right during flow calibration, or it does after the actual prints starts.
I also tried redoing a successful prior print with the same results.
Edit: So far all my problems have been with the 0.4 nozzle, so I need to rule it out tas the potential defect. Coincidences exist after all…I’m currently trying a test cube in PETG-HF with the 0.2 nozzle. I’ll switch to 0.6 after that and see…
Thanks for the details, ratcha, I appreciate the help
It’s like you say, only a bit more random. Sometimes, the first layer does work out, sometimes not. And the flow grid gets messed up too, randomly.
I’ll follow your list with what I did so far:
First list:
Swap filament: check
Dry filament: check
Clean the nozzle using a needle/cold pull: I did the needle thing, not the allen wrench pull.
Run the flow calibration: check
Power cycle: if you mean switch it off totally and then restart it, then check
Second list:
Change the model print: check. I tried with different items.
Change nozzle, ideally brand new: haven’t yet replaced the 0.4 nozzle. More on this below.
Factory reset: not done. Is it safe? What will it entail?
Clean the nozzle using the cold pull method: If it’s the allen key method, no. I only did the needle thing.
Check for physical damage inside the extruder gear/compartment: check. But more on that later.
Bed tramming: no idea what that is
Checking belt tension: not done, more below
Try silence mode (lower the print speed): not done, more below.
–
The things I haven’t done yet (cold pull, tensioning belts etc.) I have put on hold for now because I’m still testing with my 0.2 and 0.6 nozzles. I don’t have a prebuilt 0.4 assembly at hand, only a spare nozzle and I don’t think I have thermal paste either so I’ll probably need to order before I can test 0.4 again.
A test cube in 0.2 came out absolutely perfect with PETG-HF. A tiny benchy, about as tall as the cube, came out perfect as well. I am now printing a 60/31/48mm benchy, again with the 0.2 nozzle, to see if messes up or not. It’ll take 3 hours.
I’ve had a poop left dangling after the filament loaded, that I had to remove manually before it landed on the plate, and some curl of filament occasionally sticks to the nozzle tip, but aside from that 0.2 is behaving so far.
I’ll post the progress as soon as I have more results.
