trying to print directly from Bambu Studio after updating to this firmware gives 100% failures parsing gcode
edit: to be clear this is with bambu studio ver 2.0.2.57 - i’m rolling back to non-beta firmware on the printer as that was working fine. RIP using my AMS2’s drying functions yet.
Is this the update that everybody is duly trying to avoid?
You mean that auth control firmware? that’s not beta anymore. that hasn’t been beta for like two months now dude.
No, the update that everyone is trying to avoid right now is any of the 2. Bambu Studio releases as they are buggy.
moi il a fonctionner avec quelque bug , ne peu pas choisir la langues au redemarrage donc obliger de redemarrer l’imprimante , mais jai reussi a imprimer , et ams 2 pro et pris en charge aussi oui
I updated two of my X1C’s to this and they’re both giving me the same error every time I try to start a print. Even when I try to start one from the SD card. I’m currently downgrading them to the previous version.
Same error with my X1C …
Any official news ?
Reverting to 01.08.50.14 Beta was the solution for me.
PS: This Version has the new UI too.
this started on mine today after i did the update as well. the firmware is broken.
Downgrading to see if that fixes the issue 
i tried “previous versions” and it didn’t offer me that one. is there a way i can tell it either via handy or at the UI to pick that specific beta?
Same problem. Internal original g-codes too.
Next problems in this firmware what I found:
Filament sensor not work if using external filament. AMS works OK for me (tested Auto Refill with 4 filaments - all OK)
Not possible (or buggy) regulating fan speeds while printing.
I realy love this new GUI. And from fw 1.8.50.14 is saved K-faktor into filament presets in AMS - not needed to setup it every time after power on.
For the Beta-Versions like 01.08.50.14 Beta, you have to enter the Beta-Firmware-Program. Then you can see this version in the mobile app at the older Firmware list.
I had to enter beta program to get 1.08.50.18 - but i never had 1.08.50.14 (joined after) so it isn’t listed in “previous versions” for me
You probably don’t see this version in the old versions because you are not on a newer one.
I don´t know if you can choose this version without installing the buggy one 01.08.50.18 Beta first.
Sigh. Omg bro. Seriously?
I’m OP. I was on the buggy version. When I rolled back it didn’t offer me. The .14 version as an option. Just the 18 and the non beta I had been on previously.
Maybe I can update one of my X1C again to the .18 version to show you the list of the older version when I´m back home from work.
I’VE SEE THE LIST OF OLDER VERSIONS
it did not contain the .14 version for me, because i’m assuming it’s based on your install history - not their posting history.
Nope, I´ve never installed .14, I jumped directly to .18 from a non beta firmware.
I can confirm 1.08.50.18 is bugged while downgrading to 1.08.50.14 works.
