r/BambuLabA1

I had tried to print something that the print called for pla and I used petg . It seemed ok i change temps to adjust. 16 hrs into it . I had some air printing . I was watching it remotely from work. So I stopped the print .230am I dont allways make wise choices I hit the home button twice after toolhead came down in the failed cobra fang print. Now im not sure did I break it?3 more hrs til I can check

Hello, im really hoping someone can help me out here on why the O and R are filled in ive tried different fonts and every setting i can think of and nothing works because i do not want the O and R on the word Frontier and Volunteer are filled in in the middle meanwhile the R D and P on Fire Dept arent filled in i dont get why those arent but, the O and R are filled in im super confused so im really hoping someone here has a solution for me, this is getting really frustrating why i cant figure this out on my own

Hey everyone,

I currently own a Creality Ender 3 V3 KE and overall I’m pretty happy with it. The print speed is already quite good, and I mostly print smaller things with PLA.

Lately I’ve been thinking about upgrading to a Bambu Lab A1 Combo mainly because:

• it seems much more user friendly
• less tweaking/calibration
• automatic filament changing
• multi-color printing with the AMS Lite
• more “it just works” experience

At the same time, I know my Ender is already pretty fast, so I’m wondering if the upgrade would actually feel worth it in daily use.

I also don’t print huge models very often because filament costs add up quickly for me.

For people who made a similar switch:

• Did it feel like a big upgrade?
• Is the AMS Lite actually useful long term?
• Did you end up printing more because it was easier?
• Or is it not worth upgrading if the Ender 3 V3 KE already works well?

Would love to hear honest opinions from people who have used both 🙂

Hey folks, I’ve got an A1 and I’ve really been enjoying it. I find timelapse videos of prints really satisfying and wanted to make some of my own.
I’ve found the Timelapse looks a bit pish if I use the default camera option and tried printing a GoPro mount that attaches to the cutter but it’s a bit shaky.
Has anyone got any good set up ideas/recommendations on how to film some?
I’m guessing that maybe a tripod separately would be better but thought I’d ask the group to save some trial and error.

Today I learned how to manually update the default Bambu Lab filament profiles with my calibration results (i.e., without having to use custom profiles). I've seen a lot of frustrated posts here and on other sites about not being able to change the default Bambu Lab filament settings in Bambu Studio, so I thought I would share.

Before I go into the process, please note that this requires some basic technical skills (i.e., understanding JSON) and backups should be made before modifying any files.

Situation: You want to use the default Bambu Lab filament profiles, but want to change the default nozzle or bed temperature, fan speed, retraction, etc. You cannot presently make these changes through the Bambu Studio interface (it will only let you save any changes as a user preset). This is a problem if you want to use the RFID tags with the AMS or you have to remember to later select those filament profiles.

Solution: You can manually edit the JSON files for each filament preset in the application's configuration. What follows is a summary of how to do this on a Mac, but presumably you can find the same files on the PC and Linux versions as well.

Step 1: Open the Configuration Folder

Go to the "Help" menu and choose "Show Configuration Folder". These are also accessible under Library > Application Support > BambuStudio

Step 2: Navigate to the filament presets.

These are located under system > BBL > filament.

Quick overview of how the filament profiles are saved: The filaments are JSON objects that can be edited using TextEdit or any coding software. The files themselves use a system of inheritance.

- The base class is fdm_filament_common.

-- Then there are instantiations of the base class for each filament type (e.g., fdm_filament_pla).

--- The filament base class is then instantiated for each manufacturer (e.g., Bambu PLA Basic @ base, SUNLU PLA Matte @ base).

---- Then the manufacturer filament base is instantiated for each printer (e.g., Bambu PLA Basic @ BBL A1)

----- Finally, if there is a nozzle, specific profile (e.g., 0.2mm nozzle), then there will be yet another file (e.g., Bambu PLA Basic @ BBL A1 0.2 nozzle).

Step 3: Modify the JSON.

Each files contains set parameters (e.g., manufacturer, what it is inheriting from) and which printers it is compatible with (e.g., "Bambu Lab A1 0.4 nozzle", "Bambu Lab A1 0.6 nozzle". Any and all other parameters can also be set by adding them to the JSON (e.g., textured_plate_temp_initial_layer). The parameter names can be found by hovering your mouse over most input fields.

For example, I updated the base Bambu Lab PLA Basic profile to use lower temperatures because I am getting overextrusion.

Before making any changes, I recommend saving a copy of the profile in that same folder. This way you can quickly revert back if something goes wrong. Also, please note that updating Bambu Studio will overwrite any changes you make so you might want to save backups of your edited profiles.

Step 4: Confirm that it worked!

To see if the changes were successful, you can click on the three dots next to the filament to and choose "Edit".

You should then see the updated settings showing in the filament profile (see the lower PEI Plate and nozzle temperatures for PLA Basic).

Potential Use Cases

• Changing basic settings such as the bed plate temperature, nozzle temperature, flow rate, or fan speed for the first layer and for all other layers.
• Updating the cost information if you live in another country
• Reusing RFID tags (untested) with third-party filament.

I’ve never 3D printed anything before, but I’m very impressed by some of the things I see people make on r/fdmminiatures with the A1 and think I’d like to try it myself.

I am concerned with the fire risk posts I’ve been seeing lately, on one post with a failed thermistor there were maybe 5 other people who said they’d experienced the same thing. I saw a post claiming there have been over 200, which sounds like a lot, but if it’s only old models and they’ve sold hundreds of thousands of A1’s with no issues since I could probably accept that. How isolated are these incidents?

Also, for every post where someone says they’ve been running an A1 for hundreds of hours with no issues, there’s at least one post of someone getting very upset troubleshooting.

It seems people have very different experiences with the A1, but they seem mostly favorable for the price point. This might not be the best place to ask, but would you recommend the A1 as a first and hopefully only 3D printer? Do people typically spend as much time troubleshooting as they do printing? Are there a lot of hidden costs with troubleshooting, buying replacement parts and filament from failed prints? It seems like it could be a very frustrating hobby, but if I can get the results I’ve seen on r/fdmminiatures a dozen or so hours of troubleshooting seems worth it.

Thank you for any help!
