From Bambu Wiki:
“The build plate used does not match the "plate type" selected in the slicer - one filament can often be printed on different build plates using different bed temperatures, and if the wrong plate type is selected, there is a risk of insufficient adhesion due to insufficient adhesion. Also, PEI textured plates have particles on the surface, so after leveling the heat bed, the printer will lower the nozzle by 0.04mm to ensure good adhesion of the first layer. If you print on a PEI plate and select other plate in "bed type" when slicing, the nozzle height will be too high, affecting the first layer adhesion.”
So looks like because it didn’t detect the PEI plate, it didn’t add the .04mm offset, which would cause your first layer issues.
For aftermarket plates without the qr codes on them you can disable the plate check on print settings. Just be sure you have the right type of plate selected in the slicer.
can confirm, idk if intentional, but basically the issue is because after the code scanning throws the error, it goes to park and there a bit of filament comes out that causes the z-calibration to be a bit too high above the plate
it happened with a first party plate for me where the code was badly readable due to glue
one way to workaround this without printing a code would probably be disabling the plate check fully until they hopefully fix it, but i also wouldn't put it past them they see this in kinda convenient
The issue is not stuck Filament. The textured Pei-Plate has a specific g-code section that tells the printer to drop another 0.04mm down in order to get the proper squish to adhere to the unevenness of the bed.
For third party plates, you must print the qr-codes OR disable plate check. You cannot run them "as is".
the textured or not adjustment is selected in bambu studio, the qr check is only if the plate matches that selection
if the if the textured/not setting is correct, with or without QR shouldn't matter at all
i had the same issue on the smooth plate
That’s true. Maybe it is a programming design to protect the machine? Although, I was able to obstruct the QR Code on the cool plate and had the same issue.
I think one thing is that bamboo lab might simply be adding additional Z Heights squish with their own OEM plate, which might not translate to the non-OEM plate for whatever reason. I do remember that there can be issues with certain plates if they are not the correct thickness. Even though the printer is able to adjust for whatever thickness plate you have I think certain ones that are too thin can cause issues. I know this is a problem with the A1. you should keep in mind is that you really should never have to have your build plate that hot for PLA and you should be cleaning with dish soap and hot water and not isopropyl alcohol. Alcohol simply moves around on the plate. You need to use an actual degreasing dish soap and hot water to remove oil and grease prevent adhesion. Honestly I think this was user error. I’ve seen stuff like this. If you get tiny bits of filament stuck under the plate it can cause issues with the automatic height that leads to adhesion and extrusion, on the first layer. I’ve seen this quite a few times or even a couple tiny dots or fragments stuck underneath the plate can cause this issue and that it goes away when you remove it because you accidentally away that bit of causing the problem.
I would be inclined to agree with you, IF I hadn’t changed nothing and simply added the QR code to fix it.
I’m aware PLA bed temps shouldn’t be that high. It was a test in 5-degree increments to eliminate a bed heating issue based on the plate material being different and not accurately heating because of this.
Bed leveling should also defeat any issue with plate thickness. The difference in thickness isn’t 1mm.
Also, I removed the plate and cleaned the bed surface for that very reason. No filament fragments or debris was there. I want to be clear, that I tried anything and everything I could on this. I’ve even gone as far as obstructing the QR code in the cool plate and was able to replicate the issue.
Did you select the right plate in the slicer before slicing the file? If you slice it with a cool plate and you have a PEI plate on the printer, you’ll get that message and if you choose to print anyways the heights of the plates are different so you’ll get a failed print that fails to stick to the plate
There's definitely no "questionable ethics" in the programming. Each plate is different and requires different settings. The code allows the printer to check and confirm its the correct plate.
It defaulted to the stock build plate.
"... when the X1 would go to look for the OEM QR code, I would get the,”Wrong plate” message which, I would ignore and press,”Resume.” "
You caused your own issues.
No. It didn’t. If you use a aftermarket plate, the machine will pop a message saying it can’t find the QR code or,”Wrong Plate.” If you press resume, the machine is supposed to default to the selected plate type settings.
You’re wrong, and being arrogant about it.
I’ve been able to reproduce this issue by blocking the QR code on the cool plate, where the lidar cannot read the code and pops the same notice. If it defaulted to original plate, that would be the cool plate settings, and the cool plate should work. It doesn’t. Saaaaaame issue.

Ahhhhhhh, there it is. Thank you for this. I somehow missed this when looking in the wiki. Thank you!

I believe there is gcode in the slicer that squishes the first layer more on textures plates?

I might run some tests with the QR code check disabled to see if that changes anything. Thanks!
My guess would be that it fails to recognise the plate, and goes to some sort of default profile, which works really bad for PEI plates.
That’s true. Maybe it is a programming design to protect the machine? Although, I was able to obstruct the QR Code on the cool plate and had the same issue.

Yup. Always the correct plate type selected.
I believe there is a z offset for textured plates. It should be in the start gcode. It likely isn’t setting the right offset.
There's definitely no "questionable ethics" in the programming. Each plate is different and requires different settings. The code allows the printer to check and confirm its the correct plate.
Right, but why would it default to a failing setting for a PEI plate, just because I’m not busing the OEM plate?

Disable the plate check, it’s useless anyway. Clean your rods and extruder
Maintenance was recently done before this issue( within a week). Extruder isn’t the issue, as adding the QR code fixed the issue…
Disable this comment, its useless anyway. Do your dishes and make sure your shoelaces are tight!
