It seems like my first layer has issues with under-extrusion/lines having gaps and not adhering correctly.
I have tried the following:
Increasing the flow rate as per calibration (The calibration doesn’t seem the best, I will post the results below. If I could get some assistance on recalibration, that would be amazing!)
Cleaning the textured plate with warm water and soap as well as 99.8% IPA.
Flipping the plate over
Trying a different 0.4 Nozzle (Had a hardened steel one)
Print settings were printed with Flow Rate Compensation enabled
What I haven’t tried
Bed Tramming
A Cold Pull
The Filament was ESUN PLA SF In standard black. All settings default as per Bambu PLA except for flow rate which was calibrated using bambu studio calibration.
Attached below are the images of the best calibration I could find as well as the first layer print results:
I have looked at the other posts and tried what they suggested but to no avail, I normally saw the nozzle too close to the bed but this seems like it’s too far.
I have a similar issue…tried everything you listed and more, including tramming and making sure everything mechanical is in order., but no fix yet.
Bambu us not even responding to my ticket for weeks, I don’t really know what to do anymore.
I am really depends on good first layers for my designs, rendering the printer almost useless for my intended use.
Looks like I in the same boat, I have a few sections where it bends as well and it seems to be in the same location of the “seperation”
I tried the following: Bed Tramming, Hot end tightening, Cold Pull, Checked the extruder gears, watched the entire print to ensure the extruder didn’t skip, and I checked it and whilst mine doesn’t look as bad as yours, it lines up. Did the exact same thing after flipping the textured plate, exact same location. It has to be the bed at this point.
I have opened a ticket and let’s hope they reply. The only thing I haven’t tried is adjusting the Z-Offset and that’s because that’s a bandaid fix to an issue.
Yup, Bambu is sending me a new bed.
Mine seemed almost twisted, there was no real rhyme or reason to where it had dips.
I had to mention the word chargeback to the live chat person before they even looked at my ticket (its been 2.5 weeks of troubleshooting this)
I also tried the z-offset, lowering it by .002, and it performs better, but as you said, its a band-aid, but it will at least tide me over until the new bed gets here.
Still a bit salty about having to tinker this much with a brand new bambu.
I have spent over half a decade tinkering on other machines, and I just wanted a tool this time.
This is my first printer, so I was really confused when it happened…
Mine looks like it’s bent where the magnets were, there’s dips before every magnet, Top left also has a dip across the 45 degree angle. It’s the only thing I can think of, I improved the print quality by increasing the flow rate so that’s helped a lot even if my edges are overextruded on the first layer now.
The original photo in my first post was bottom right, was the top left as per this photo.
Yeah, I got mine about a month ish ago myself. Its a good printer, just marred by that one issue. (They probably had to get so many bed out due to the recall earlier this year that it affected QC)
Luckily I have more than enough technical competent to do the assembly myself, I do feel for the ones that dont feel they can.
