I don’t have the same issue as the hunkytenor, I simply can’t get the printer to stick anything to the bed. Not even the calibration lines. I provided bambu support with a video that showed this very clearly. Waiting for their feedback as they already sent my logs to the engineering team
I’m not by any means suggesting user error or that I know more than anybody here
My only goal with the bed leveling suggestion was to assist in if not finding the solution to your issue perhaps you might pick up on something about how the printer is performing the leveling procedure during a calibration or pre print sequence after manually leveling
The failure looks to me like the nozzle is too close after the first layer on the bottom left
Is it still doing a full bed level pre print or has that changed after your firmware update ?
Perhaps that is something to do with the firmware and z offset ?
I wrote that I am doubtful that it’s the firmware but also that I could be wrong
If we never made mistakes then we would never learn anything
Sorry I did not see that you did already level your bed
It was just a suggestion
I’ll sit down now
Good luck
My feedback with my machine is that its printing on the textuered plate, i need to go back to the cold plate and up the temps to see if this will work as the calibration lines wouldnt even stick to the cold plate.
I have added to my log file though that the same part file from before the update is now getting awful top layer finish but that was with a newly sliced file.
If nothing else its been another great learning experience. I have stripped out the hot end and extruder as i wanted to be sure it wasnt a blockage.
I have my 2 ender 3 machines running other jobs so im still ticking along.
Correlation does not imply causation.
I don’t think anyone is implying user error in this thread.
Exactly why the meme was posted in response to that particular user.
Seems like multiple issues then.
It’s a tough question to answer without more info. But hardware does fail and sometimes people make mistakes. These are complicated machines doing complicated processes with different user inputs and a bunch of variables. I completely understand wanting to blame the firmware, as it would be the simplest explanation (and that’s usually the right answer). But, it still doesn’t mean it was the firmware. At the same time, it doesn’t mean it wasn’t either. You guys very well could be right that it is the firmware. I would just be surprised by that, given how many of us are not having these issues.

Yeah, that’s weird.
Maybe those of you with these issues should post when you purchased the machine and when you received it. Then also confirm if you have a completely flat heat bed. Maybe some of the warped heat beds are causing more issues with a firmware tweak?
But I checked the firmware release notes and nothing jumps out at me as a change that would cause these kinda problems, so I’m stumped.
I agree that it may possibly have to do with the batch or a slight change in production during a certain time for only a couple of these machines to be affected this way. Ive been facing similar issues where everything has been printing flawlessly until the update and suddenly nothing has been sticking to the bed.
I bought my X1c around mid January and it arrived on the 20th of January. Have been printing almost everyday with no issues until a few days ago.
The only thing I saw was a change to thermal runaway protection which you would hope would not actually change the temperature control loop, at least not without complaining about something and still why only a very few machines?
Yeah, that was the only one that I thought might be causing problems, but I assumed that one would be impacting more of us if it was the issue.
I guess it’s important to note release notes don’t always contain all changes. The notes are merely a list of changes a software developer decided to share.
@SirWill May be it would be an idea to release a new BETA version of the firmware, which is the old FW and only enable it to those who have the problem, may be 3-4 users, so that they can check whether this will eliminate the problems ?

This would be a great way to just rule it out

Just to rule out the following:
Since the new firmware release date was quite close behind the release date of the new BambuStudio software, did you by any chance also update the BambuStudio software? If so, have a look at the Printer Settings, Machine start G-code and check if there is some new Z-offset in there that is higher than previously.
I am not running the latest firmware and slicer software. With one of the previous releases of the slicer i think they made an adjustment to the Z-offset for the textured plates, assuring better adhesion to that plate. Maybe there is something changed again, causing the filament to not adhere to the plates.
Actually, this might also be something that you could test: try to lower the Z-offset in the machine start G-code, does that help with the bed adhesion? I think this could be an easy test to perform. If it doesn’t help, well… But if it does, at least this might be a temporal solution for anybody who is currently suffering from bad bed adhesion.

It could be a batch of hardware components that are impacted by the FW update, if it is indeed FW related. Maybe the sensors are misreading for some people leading to incorrect Z offset or Z levelling of the bed. Hope you guys find a solution soon. My X1C and X1 seem fine on the latest FW

I fully agree with that BUT it may be more complicated than that - for example, Bambu could use different suppliers for the exact same parts / same specs but still without in some situation different behaviors over time, and hence you may have some differencies over time between the exact same models. Or one supplier for first batch and then (to reduce cost) another supplier for next batchs. And so on.
Not saying this is happening, but this is something that has already happened for many hardware devices. And of course the firmware should accomodate with that (#IFDEF supplier1 …).
Here it seems only a very few number of people have some issues, so i would also suppose that it’s something else (maybe something broken “by coincidence” at that time, thermistor, fan regulation, whatever).
Hi Gander,
I read your post and wanted to try my X1C at printing with pei textured plate. My printer is from October 2022.
All new firmware and software updates completed. Oem presets and profiles for both PLA and PETG. The plate was not washed before i started it was just in my plate holder. Both prints stuck to the plate as it should. No zits on the PETG print. The AMS i used was at 20% humidty. Both spools came out of a new box straight into the AMS.
I really hope everybodys issues are fixed soon.

The Z offset being out makes perfect sense as I’ve seen other posts in here about the nozzle being too low and dragging across the bed ruining the build plate
I have also read and experienced my bed being at the bottom after a print, hitting home and the z axis motor skipping because it tries to drop down before it goes up
Here’s an interesting thing that previously with the old firmware I could not do, if my printer finished a print and I tried to manually drop the bed down the screen would prompt me to home the printer first
Now after a print I find that the Z, X, and Y axis can be moved without the error
The more I read the more I’m starting to think maybe this is a firmware related issue, not so much a bug or incorrect command but rather some commands that were unintentionally turned off // with a couple of others such as the z offset being tweaked slightly
If the Z offset does not switch back between the different plates when the printer scans the plate then + - 0.02mm can make a drastic difference
I’ll sit back again and continue to watch our saga unfold until a solution is found lol
Same boat, I am not new to 3d printing, have hundreds of hours logged on my X1C and haven’t been able to get anything to stick to the build plate since updating the firmware.
I cant confirm if it did it before the update but mine now certainly grinds at the start of a new print few times. Reading another thread it could well have been when a tall print was printed before it.

Where is it dragging?
Mine drags at the rear of the plate on the little extended part (but not on the printing surface) at the start of the print when cleaning the nozzle during bed leveling. Other users have have posted some pictures of the issue and I haven’t been able to find a clear answer on if this is normal or not (some say it is to be expected).
An image of the issue from another thread:
Because some of build plates in the shop don’t have coating on them, I assumed it was because this area was coated when it shouldn’t have been and the nozzle thinks the bed is in that area is lower than it is:
But what’s interesting to me about that thread, users are saying they had good prints for a while, and then all at once couldn’t get anything to work. The coating was rubbing into the nozzle and causing a clog.
This was back in December so before the firmware updates. Perhaps the nozzle tips are getting damaged and causing misprints? Maybe a firmware tweak with Z axis made this damage worse after the update (more damage all at once instead of a slow drip like before)? If the nozzle is bent or pinched, that would cause all sorts of problems to flow rates and temp, and probably cause bed adhesion problems.
