PEI working marvelous but not the cold plate. HELP!

PEI working marvelous but not the cold plate. HELP!

When I’m printing with the PEI prints awesome but when I swap to the cryo plate all I hear is scratches (terrifying) can I fix it when printing directly from my phone ( not using Bambu studio ) ?

Help please!

Please can someone help with a really basic dummy guide!

My son (aged 13) has the Bamboo A1 Mini and is designing his own things through OnShape!

He does this on my work laptop so we can't install anything!

Is there a way to get his designs from OnShape to print on the 3D printer?

If yes please can you help with a dummy's guide as I am really struggling to help him!

Thank you in advance!

High pitch whirring/buzzing when idle?

I know PSUs etc can do this but just wanted to check

Today is day Zero - Hi

Picked up a used A1 Mini this morning with a decent bundle attached to it, couple of build plates, three nozzles including a hardened 0.6 for whenever I get there, a Sunlu S2 dryer, and a spool of Fiberon carbon fiber nylon that I have no business touching yet. Firmware updated, sitting on the shelf in my garage workshop with a role of PLA I picked up this afternoon. Good enough for now.

Not looking to be any kind of expert, I’m a tinkerer with too many projects and not enough enclosures. Got ESP32 and Heltec boards that have been sitting naked on the bench longer than I want to admit. Also have a Realistic 31-2020 graphic equalizer missing some slider caps that I’ve been meaning to do something about for years. Now I might actually be able to.

I’ll figure it out. I’ll be reading the sidebar, but any day zero recommendations for a new Bambu owner are welcome. Just wanted to do the intro, say hi and let you know I’ll be lurking and learning.

Which of these 2 for the rails?

So ive seen these 2 recommended but was wondering which is best. Also seen 21013 for the other parts.

Need help troubleshooting

When I print this piece, my printer leaves a bit of filament inside the square while trying to cover the top of it, and this only happens on the first layer. I am using the default settings. Do you have any advice?

Modifying the default Bambu Lab filament profiles based on calibration results

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.

https://preview.redd.it/1f01w03nf32h1.png?width=588&format=png&auto=webp&s=ae0c92bf8d148ba032dbd590462428805712a3fa

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.

Anyway to Save?

i used a friends third party filament and let it print overnight....

anyway to save?

EDIT: freed the blob! Thanks for the advice!

my 9-yr old learnt CAD to make this - a tiny version of his 3D printer!

It might have taken hours of messing around with tinkercad tutorials, teaching him that the printer cant print in thin air, and showing him how to use the slicer, but he was finally able to design and print this - a miniscule model of his printer!

If anyone wants to print their own, ive uploaded his model to makerworld: https://makerworld.com/en/models/2807327-tiny-a1-mini-model#profileId-3124056

TPU buckles and bends while loading into A1 Mini (No AMS)

I can't load soft TPU into my Bambu A1 Mini. Since the filament is too flexible, it just bends and buckles inside the toolhead before reaching the extruder gears. Every time I push, it flexes instead of going down. How do I get it past this bottleneck?

UK users which lube do you use?

Did my first round of maintenance and after reading the guide multiple times still put the lube in the slightly wrong places lol.

Which do you use? Ive seen superlube recommended but doesnt seem available in the UK.

Also which grease for when I run out of that

Many thanks

I built an Android app to manage 3D printing filament — looking for beta testers 👀

I got tired of tracking filament with spreadsheets and random notes, so I started building my own Android app for it 😄

It’s called rocchetto and it’s focused on making filament management actually useful during the real printing workflow.

Current features:

  • spool inventory (FDM + resin)
  • OCR label scanning
  • NFC tag support
  • .gcode / .3mf import
  • MakerWorld & Printables link analysis
  • automatic filament usage estimation
  • print cost calculation
  • low stock notifications
  • filament color matching + finder

The app is still in beta and currently completely FREE because I’m trying to find bugs, improve the UI/UX, and understand what makers actually want before release.

At the moment it’s Android only.

I’m looking for some testers from the community 👀

If you’d like to try it, just leave a comment and I’ll contact you in DM with the beta access link.

You can also see the project showcase here:

A1 mini left alone. The 3d printing newbie shenanigans

Hey there,

I started playing with 3d printers around 1 year ago, so I don't consider my self any kind of expert. I would like some help to identify the root cause that led to my 3d printer behaving in this way. I have an A1 mini that was gifted to me (brand new), with a black PLA basic, by bambu. Before every print, I set the auto bed leveling and the flow calibration to ON.

I wanted to print some stuff on Saturday, so here is the timeline of what happened.

I stared in the morning by printing 2 models, around 3 hours each. Both models came back very nice and I was happy with the result.

On mid-day I sent another print, a bed scraper model, which took around 40 minutes to complete. This is the first print that I enabled the ironing function, with a speed of 65 mm/s, flow at 22% and line spacing at 0.15 mm. Print came out perfect.

On the evening I sent the printer this model, the "no texture, light 15% infill" version. All was going smooth up to a point that the printer screen showed an error with the SD card (MicroSD card read/write exception; please remove or replace the Micro SD card [0500-C010 ....]). So, I remove the SD, re-insert it and still the same error appears. I remove th SD again, plug it into the PC to check the free storage, and I removed some of the timelapse videos I had, to make some space. I plug the SD back and the printer continues to print like normal.
At this point, there were around 30-40 mins to finish the print, but I had to leave the house, so I left the printer alone.
I came back 4-5 hours later, only to find the print still "trying" to print. Head and fans where moving, no fillament was flowing, but I saw that the printer had walked a bit (around 45 degrees relative to it's normal position) and panicked so I immidiately stopped the job without observing much more.
You can find all the pictures I took here.
Strangest thing is the scratch on the bed surface and the tiny nick of the Z axis column (you can see that in the pics). Could something trigger the printer to restart at some point?
Is it possible that the ironing made some fillament get stuck on the head and/or damage the silicone sock, leading to this?

Thanks!
