Because you mentioned temperature changes as part of the FW: If it was with the standard presets in the slicer (Bambu Studio) it has not changed by the FW itself.
If you have your own presets for filaments, an update of the Slicer and for sure not an update for the FW will not overwrite that information
I was able to finish printing the AMS tool by changing nozzle temp to 230c and first layer bed temp to 65c.
I also noticed the calibration lines that are printed at the bottom of the plate has globs at the end of the line since the FW update. Could it be the bed /nozzle temp and flow ratio are inaccurate since the update, e.g., 225c nozzle and 55c are actually lower and .98 flow is more than it show?
I believe those blobs exist because of a previous firmware fix where previously we would get filament oozing when the print was bed leveling and after the first layer inspection
There are moves now that although the boogers of filament are still present after the first layer inspection or even if you use Orca like many of us do and have first layer inspection off youāll find the print head tries to get said blobs hung up on the tail end of the last line laid down then again on the purge lines at the back
This way (99% of the time) we have a clean nozzle at the beginning of the actual print
If you turn off first layer inspection and watch the first line at that your printer puts down at the front before it shoots over to the back corner for the purge lines the print head will quickly move a bit to the right then back where a little nugget should get stuck to and pulled off the nozzle before it travels to the back center and purges X then Y and back to the rear center again before givin er
I ve had the same problems exactly after havin* nothing but success for weeks???
Hello all,
My first post. I did not know about this issue and upgraded my firmware on Apr 8th. I had problems with bed adhesion but have mostly sorted them out.
Here is what happened with me:
I do all my prints with at PLA at 220 degrees with the PEI sheet @ 60 and a layer height of 0.2mm.
After the update, had problems with bed adhesion. First thing that I found was the area on the PEI sheet where the head cleaning is done had worn a spot down to the metal. This had been causing the head not to get clean and it would get bits of plastic stuck to the head which was dragging up stuff printed on the first layer. I flipped the sheet over to a fresh PEI sheet and cleaned the head. I removed the silicon cover and made sure all filament was gone from the head. This improved printing a lot but still had problems often.
The change which got me back to having successful prints most of the time was to set the first layer height to 0.15mm. I suspect the firmware bed height alignment has changed and maybe is now higher than it used to be. I wish I had a way to test for this.
Hope this helps someone else.
This wear is intentional, not a fault. It does not affect your prints.
Check the description of the plates in the Bambu store. They all say:
Before auto-leveling, it is necessary to repeatedly rub the nozzle in the special wiping area of the build plate to completely remove any residual material at the tip of the nozzle. The coating in the special-designed wiping area will gradually become worn over time. This is normal and does not affect print quality or nozzle lifetime, so there is no need to worry about any quality issues.
I am completely unhappy with Carbon X1-C
Having so many issues from first days to now. I have just send them a request please refund my money back or take this machine and send me a working one.
Here are some of the issues:
MCU fan fixed.
Extruder and AMS issues many.
Print quality issues. Software / firmware just too many to list.
Just like I been complaining to Bambu Lab tech āI am NOT a beta tester!ā My expectations and companyās promises are not met.

Hi Chad!
Iām sorry to hear you are having issues, but I see this is only your second post here looking for help.
I donāt know your 3D printing level of knowledge, but we get a lot of people starting in the 3D printing game that have expectations that itās like buying an inkjet printer - plug and play. Itās not.
Bambu markets this printer as an āeasy to useā machine.
It is.
But that is only compared to the other printers in the market!
3D printing is a complex subject. We are trying to create objects using melted plastic from many companies, each is a unique blend requiring proper settings. Weāre also trying to do this to hundredths or even thousandths of a mm accuracy!
Even the smallest change can result in failure, and sometimes thatās after hours of work.
If youāre not up to having that reality, I absolutely agree your should return your printer.
I get your frustration, trust me on this, I do. Iāve been in this crazy world since 2015 and canāt tell you the number of times Iāve wanted to take a hammer to my damn printer, so I get it.
However. If you want to make this work, there are many helpful people here eager to help you solve any problems you run into.
But be aware that it will take a few things on your end -
Seriously. You can get help here. Most issues are settings or misunderstandings of the subject and we can help with those.
The fan is a known issue and there are solutions. BL will happily send you a fan or give you a store credit. Read this, thereās a long discussion with solutions:
https://forum.bambulab.com/t/noisy-mc-board-fan-and-possible-fix/
Now, if youāre just p*ssed off and want to send back your machine, fine. Best of luck if you feel youāll find an easier one to deal with. You wonāt.
But if you want help - see the list above.
BTW - If you do wish help, in the future make a new post about each issue rather than leaving a comment on a similar one. Youāll get hundreds more people seeing it and faster responses. Many of the āregularsā here only look at new posts, not ones that are long discussions, often marked āsolvedā.
This discussion is about a firmware released months ago and since updated. Your post has nothing to do with this subject, eh?
I canāt print anything that uses supports. 100% failure on tree supports and with regular support it messes up the print so bad itās not worth it.
Not sure what changed. I even slowed the prints down to 30 and still the trees break or fall over. Nothing works. Support filament, more walls, infill, auto settings are the worst.
Anyone else not able to print anything with supports? Iām kinda fed up at this point. Did a full maintenance cycle and ran a test print with all Bambu filamentā¦ Tree supports came lose at the base and fell over. Essentially my printer canāt print supports. The advice I keep getting is to slow the printer down but if 30mms is to fast how slow should I be going? 1? 0.5? 0.01?
Hi I_Anthony,
Did your problem start with the current firmware and was it ok in the past ?
Iām running the current firmware with no problems but I also use custom gcodes with the WhamBam and the Bambu Texture plate.
What bed plates are you using ?
What filament are you using PLA ?
What Slicer are you using Bambu or Ocra ?
Can you post a photo of the item you are trying to print and the tree settings used.
This will help so we can see if we can help you out with a solution.
I was having the same issue but found that the settings for the āCool Plateā were set to 0 degās. Once I reset those, they stuck just fine. In fact, sometimes too good. I mainly use MH Build PLA and I set the nozzle to 220C, the build surface to 35C for the first layer and 40-45C for the remaining layers.

I was able to resolve the problem with the help of this group.
I reset the printer and reinstalled the update. Same for the slicer. I then resliced the file and it worked. Not sure what the problem was but it has been resolved.
With Bambu, are you locked into the loaded or new replacement firmware, or is there flexibility to backdate if a specific feature or element is changed, but does not work for your needs?
Previous versions were inaccessible before the last firmware update. Latest version added ability to go to previous version if using the Bambu Handy app.
I had the problem and I asked for a way to roll back. I got the run around. Then later the Handy App had the ability to roll back. I tried at least 10 times after the update and followed all the directions. Once I rolled it back it worked. I then updated and rolled back for a total of 4 times. Each time updates the printer would give z axis stuck. Roll back and it worked fine again. That clearly lets me now it is firmware related. And now once again Iām stuck with a printer that canāt print because the rollback firmware folder has no content. Fml.
