So after the latest update my printer just gets stuck in the “preheating buildplate” mode and wont start the program. Anyone else having the same issue?
The flow rate auto-calibration feature is broken. The auto-calibration just prints air.

Currently using the previous firmware patch. Was the only way to get it to work again.
please how can i return my old firmware. after update printer doesnt work properly. UI is terrible. im i hate this one. help me please
Go to “devices” in bambuhandy app. on the icon up in right corner you can enter and see “firmware version”. After clicking scroll down and you can choose “i want to downgrade to a previous version”.

Just updated to latest version and having similar issue. I printed things fine then today it just decided to not print anything from wifi or local.
Me!!! However, if I cancel the job and start it directly from the printer’s screen, it prompts me to select which filaments to use from which AMS. After making the selection, the print starts normally and the filament loads as expected.
Broke my own rule this morning and updated the X1C firmware even though nothing was wrong with the existing firmware, and got exactly this behavior. The WiFi interface associates, and the Windows program believes it has downloaded the print job to the X1C, but then it just sits there “preheating” forever.
Reflashed back to the previous version, but now it simply refuses to accept print jobs via WiFi. Copying a job to the MicroSD card and then manually selecting it works great (it’s printing right now). But somehow the firmware “upgrade” has broken the ability to print via WiFi.
Thanks, Bambu.
I now have a glorified Ender 3D that only prints from an MicroSD card.
Never, ever, EVER “update” your firmware unless it fixes a specific problem that YOU are personally experiencing!
Does it actually start to heat?
Can you send and print using LAN mode? Using Developer mode?
It does not start to heat. Bambu Studio believes it has successfully sent the print job “through the cloud” but the printer just sits there “preheating the bed”.
Manually loading the STL file on an SDCard, and then manually starting it from the card, works fine.
I have not tried Developer mode (didn’t know it existed). My X1C doesn’t have a LAN (Ethernet) port of which I’m aware. Is there one? I much prefer wired to wireless connections.
To be clear: The X1C does receive the job because the little rendering of the part appears on its screen. But the printhead doesn’t heat, nothing ever changes, and it just reports “preheating the bed”.
I was trying to isolate the problem to the firmware, Bambu servers, or the software. LAN-only mode sends the file directly to the printer over your wifi. “Local Area Network” only means data never leaves your network and does not use the internet, whether it is transmitted over ethernet or via wifi.
As I understand it, Bambu’s new firmware requires that any heating or motion commands be authorized by the Bambu servers, whether they are sent through the Bambu cloud or sent directly from your computer to the printer in “LAN-only” mode. This introduces more points of potential failure. In your case, since the model thumbnail is seen, it sounds like the print is getting through the cloud to the printer, but without the necessary “authorization” to actually print. (firmware/server error).
Developer mode, selected on the printer, is supposed to allow you to send prints in LAN-only mode without the Bambu “authorization”.
So “local” means “we still need a remote connection”. Stupid, stupid, stupid.
When will people realize that autonomy, and lack of dependence upon remote connections all the time, is a GOOD thing?!?
Where do I select Developer mode in Studio, to get around this design flaw? I’ll give that a try for the next print.
Yep. This.
I’m still on the pre-security-changes FW and slicer revisions. Everything I need it to do, it does just fine. No plan to update, ever, unless there’s some significant feature change I want.
Never update “just for the heck of it”.

Not the Develop(er) Mode in Bambu Studio, but the Developer Mode on the printer touchscreen. On the touchscreen, go to Settings, then scroll down to LAN Only. Turn it on and also turn on the Developer Mode (for 3D printing only).
I have the latest firmware version. It runs without any problem, with or without Developer Mode on.
Just to be sure, you ran a calibration after the firmware upgrade, right?
Yes, ran a calibration. Didn’t seem to help.
But waiting an hour or so DID seem to help. I tried again after some delay to start via “the cloud” and magically it worked. This time. Fingers crossed.
