Why first layer scan didn't stop the print?

Bambu Lab X1 Series Troubleshooting
1

I’m new to X1C and this is my 6 print. So far all prints looked pretty good but on this print it starting to fail. It printed the first layer and I got the dialog that says scanning first layer and once it finished it continued printed. As you can see from the results of the first layer, I would have expected it to stop.

Is there something wrong with the printer or should I have done something different? Also, if anyone have suggestions to why the print came out that bad, it would be greatly appreciated.

This print is the first layer of the phone stand that came build-in with the printer.

Welcome to the forum.

It looks like your bed is some what dirty.

You can try to wash it with soap and water to get it clean again.

Try to keep your fingers off the printing surface. Always handle from the sides even when removing finished prints. Use the front tab to load the build plate back on the heatbed.

In Bambu Studio.
Under the device tab, click print options button on the right upper corner. Of the four options, the first one is the one you want to check if the setting is high, medium or low. I keep my selection at medium. Not to many false alerts.

Thank you @Barryg41 I’ll clean the plate. I hope it will help. I checked my AI monitoring and it’s set to medium.

Honestly I Don’t think it’s working properly at all. They just had a survey asking how it performed or if it did and if you had it on or off. If I have mine on it causes first layer issues if I turn it off I don’t have a lot less issues, but mine has all started since I updated the firmware to the 01.07.01.00. So may just be a firmware bug at the moment but good luck hearing anything from Bambu.

On my printer i know for sure first layer checks work and also spaghetti warnings work. Watched it happen and watched the alarm pop up with the printer stopping the print.

With all the latest firmware updates, this is my experience for my printer.

One of the lucky ones lol. But there are different components on the printers which require different firmware same “version” different code, and most likely I got the wrong firmware for my printer.

7

In my case, it obviously didn’t work. I am on the latest firmware as this is new printer. I thought of opening a ticket with Bambu lab but it require the 3mf file. Is there a way to get the 3mf from the pre-loaded models?

8

I don’t think they need the 3mf it might help them but they will ask you for your log’s, from what I’m told and after you send them the logs it still takes them forever to assist.

9

I agree they don’t need it but when you click submit it tells you that you need to upload the 3mf file.

Thats strange what did you put a Issue type? Here’s my ticket I didn’t have to summit a 3mf

That works they should be able to pull the 3mf since its theirs. Hopefully yours gets answered sooner maybe since it’s a different issue type yours might get address quicker.

I’ll post their answer here once I get it

I appreciate it, and same here if I hear anything back I will sure to post it as well.

I heard back - below is the thread. I’m surprised that they are using AI to determine if it’s a failed print. I thought they are comparing the LiDAR image against the slice as it only checks first layer if it was sliced using studio. If it does use AI, I can see why it might not work as they probably don’t have enough data yet. Collecting prints from our printers can help improve it. I assume they do. Brings privacy into question but I would like to believe they anonymize the source.

Hi Rick,

Thank you for your answer Rick. I learned something new today about how AI works in the printer, which is a bit different to my general understanding about AI.

Usually, AI models are trained offline by gathering many images. These images, along with labels indicating success or failure, help create the model. Once developed, the model is embedded in the firmware to recognize similarities based on what it has learned.

To clarify, the training process doesn’t happen while people use the printer. If needed, the model can be improved by collecting images from different printers for training in your offices.

Best,

Yaniv

Hello Yaniv,

This can happen in newer machines, as the AI needs data to be able to learn and confirm. You should see an improvement, the more you use the the printer.

Kind Regards

Thank you Rick for the response. My question was why the first layer print LiDAR check didn’t fail the print? I saw the dialog popup saying it’s checking and it succeeded and went on to continue printing. Thanks, Yaniv

Hello Yaniv,
Thank you for contacting Bambu Lab support, thank you for your patience, and we apologize for the delayed response. We had staff off over the Christmas break and we are doing our best to catch up on the backlog.
My name is Rick, and I will be assisting you.
I am sorry to see that you are experiencing problems with our product. We will do our best to assist you and provide a solution to your problem.

The phone holder that is pre-loaded is for printing with PLA, I can see from your images that you are printing in a silk filament. The print speed is likely too fast for the silk filament (printed at a slower speed). To print this file successfully you would need to re-slice it using one of the silk profiles within Bambu Studio (you could try changing the print mode on the printer to silent, as this will slow down the print speed).

I can also see that you may not be using a bed adhesive. This is a recommendation when using the cool plate as you will have adhesion and release issues otherwise. This can also result in a damaged build plate surface. The use of a bed adhesive would have helped in getting a better first layer.

I hope this information is helpful.

I look forward to your response
Kind Regards
Rick
