I’m using the non-laser version, set up in a stable, undisturbed environment — no external interference. But the issue isn’t false positives… it’s radio silence. Total inaction.
At one point, there was even a flake almost the width of a finger hanging in front of the camera — like a veil or blind — and yet, according to the AI, everything was just fine. No alerts. No intervention. Nothing.
I’ll likely have to investigate further and try to pinpoint the root cause myself. But here’s the real question:
Why should I have to?
Why did I pay for a smart, inspected, and “ready-to-go” machine… only to end up doing its job for it?
And yes, I am frustrated over some wasted filament — not because of the material cost alone, but because this isn’t a printer sitting in a student’s bedroom churning out keychain Pokéballs.
This is a production tool in a working environment, and every failed print means not just lost material, but lost time — something far more valuable when you’re running a workshop.
At this point, it’s becoming harder to defend the “smart” features when they consistently fail to deliver where they matter most.
Before this new firmware my AI detection seemed hyper-responsive, last night I had a basic print fail and it looked like the spaghetti detection should have caught it ALOT earlier than it did. I almost had the blob of death on the nozzle, but luckily did not.
I’m getting alot of “Nozzle Offset Calibration” errors with this firmware and its really annoying me… I have to constantly turn the printer off and on again, and I’ve done a nozzle offset calibration twice already. This firmware version sucks.
It highly depends on where you put your H2D, whether there’s sun light hitting from the side window or door or not; also the color of the filament. It’s weakest at shiney/oily filaments with dark colors, like a black petg.
if something goes wrong with the calibration here, something is wrong with the hardware. You can go back to previous firmware but I doubt if it would help.
Maybe, but I know I did not have this many nozzle calibration errors before the latest update. I’m going to switch filament rolls and see what happens, the quality of the left nozzle has nose dived as well so maybe its the filament.
I’ve left mine on the standard setting and couldn’t be happier. I’ve only had one model or situation where it triggered repeatedly with false alarms. However, on that one, I noticed after the print that a single string of wispy filament was attached under the tool head, and in front of the camera. I have since cleaned it and haven’t had a problem with it since.
The detection has been better than I could have ever hoped. A print failed and literally, 10 seconds later it stopped. Again… I couldn’t have hoped for better performance. I only have 200 or so hours on it, but its good for me in all sorts of print scenarios.
After this update, I found that when I intended to calibrate using the 100W laser head, the system notification indicated that the 4K overhead camera needs to be initialized. I’m not sure how to do this, and I can’t use the laser functionality now.
" 4. Optimized print quality with the 0.2mm nozzle."
What exactly is being updated? Already happy with the .2 print result after my own fine tuning. curious, but also cautious since it’s so vague.
I can verify that doing this in the HT with bambu TPU 90a, I was getting thinning layers but I believe it’s due to the rollers not spinning as freely as normal dry boxes. I immediately stopped the print and switched to my sunlu dryer and got better results.
Also why didn’t they put a standard USB port on Macs? Also more maddening? Why did Apple release a studio display with a single input… never again Apple…
I printed a lithophane with the older firmware and now the new firmware with 0.2mm nozzles. The new firmware has made the lithophanes significantly more detailed and the vertical surfaces are smoother than before.
Interesting, more detailed, in terms of top surface infill or wall sharpness? If we can have a comparison photo that would be superb.
Sounds like there’s less micro z-banding as well.
Tbh I’m quite mad at Bambu not using a USB-C as well. But in a second thought, many USB-C drives are super small and while they do well in normal day to day use, they might suffer when heat comes in. Which is a common case for H2D printing high temp filaments. A drive too small might get suffocated by the temperature as they don’t have enough surface to dissipate heat.
My AI was working pretty well prior to this firmware change. I also had a print that did some spaghetti at the end and it continued printing, and even over the spaghetti. So yeah, something with AI detection has changed. I’m debating rolling it back, but I like the new updates so a bit torn. I may try to change AI detection to the higher setting. @SupportAssistant It would also be great if they would give us access to the nozzle camera so we could see what’s going on and tell if it’s blocked, etc. I may try cleaning that as well to see if that helps.
