Cannot print with latest firmware

Important

https://wiki.bambulab.com/en/p1/manual/p1p-firmware-release-history

Bambulab decided to block printing via MQTT unless you enable lanmode only.

Consider downgrading firmware Reference !142

OR

Check the Cloud Section about enabling cloud mode

Bambu Farm

Web based application to monitor multiple bambu printers using mqtt / ftp / rtsp (no custom firmware required)

Technologies used:

Java 21 https://www.azul.com/
Quarkus https://quarkus.io/
Vaadin https://vaadin.com/

Features / Supported Devices

Feature	A1	A1 Mini	P1P	P1S	X1C
Remote View					³
Upload to SD card					²
Print .3mf from SD card¹					²
Print .gcode from SD card	?	?	?	?	?
Batch Printing⁴	?	?	?		²
AMS	?	?	?
Send Custom GCode

Currently only .3mf sliced projects are supported.

In Bambu Studio/Orca slicer, make sure to slice the place and then use the "File -> Export -> Export plate sliced file". This creates a .3mf project with embedded .gcode plate.

FTPS Connections needs SSL Session Reuse via Bouncy Castle

Without enabling bouncy castle, you will see 552 SSL connection failed: session resuse required

Getting the LiveView to work requires additional software. For more details check the docker/bambu-liveview README.
Batch Priting allows you to upload a single/multi sliced .3mf and select which plate to send to multiple printers, each with their own filament mapping.

Cloud Section

Enable MQTT connection via cloud instead of directly to printer. You can either provide the username/password or a access token.

Option 1 - username/password

Provide the username and password for https://bambulab.com/ in the format below

Option 2 - access token

The access token can be fetched from your browser cookies or a 1 liner curl

curl -v -X POST -H 'Content-Type: application/json' -d '{"account":"YOUR_USER_NAME","password":"YOUR_PASSWORD"}' https://bambulab.com/api/sign-in/form 2>&1 | grep token= | awk '{print$3}'

Configuration:

bambu.cloud.enabled=true

# Option1: Let bambufarm login and fetch token
bambu.cloud.login.username=YOUR_LOGIN_USER
bambu.cloud.login.password=YOUR_LOGIN_PASSWORD

# Option2: fetch token via curl and paste here
bambu.cloud.token=FULL_JWT_TOKEN_FROM_COOKIES

User Section

Remember to encrypt your passwords with bcrypt (eg https://bcrypt-generator.com/)

Current roles supported:

admin - full access
normal - only dashboard with readonly access

# https://bcrypt-generator.com/
#bambu.users.REPLACE_WITH_USERNAME.password=REPLACE_WITH_PASSWORD

# Insecure version:
#bambu.users.myUserName.password=myPassword
# Secure version:
bambu.users.myUserName.password=$2a$12$GtP15HEGIhqNdeKh2tFguOAg92B3cPdCh91rj7hklM7aSOuTMh1DC 
bambu.users.myUserName.role=admin
bambu.users.myUserName.dark-mode=false

#Guest account with readonly role
bambu.users.guest.password=guest
bambu.users.guest.role=normal

# Skip users and automatically login as admin (default: false)
bambu.auto-login=true

Preheat

Default preheat configuration is below:

bambu.preheat[0].name=Off 0/0
bambu.preheat[0].bed=0
bambu.preheat[0].nozzle=0
bambu.preheat[1].name=PLA 55/220
bambu.preheat[1].bed=55
bambu.preheat[1].nozzle=220
bambu.preheat[2].name=ABS 90/270
bambu.preheat[2].bed=90
bambu.preheat[2].nozzle=270

Remote View

Remote View is the ability to remotely view or stream the printer's camera.

# defaults to true, when false, disables remote view globally
bambu.remote-view=true

# defaults to true, when false, disables remote view for dashboard, but will still be available in detail view
bambu.dashboard.remote-view=true

# defaults to true, when false, disables per printer
bambu.printers.myprinter1.stream.enable=true

Live View

Live View is the ability to remotely stream the X1C camera (or any other webcam) and requires Remote View to be enabled.

Note

Getting the LiveView to work requires additional software. For more details check the docker/bambu-liveview README.

bambu.live-view-url=/_camerastream/

# For each printer:
bambu.printers.PRINTER_ID.stream.live-view=true

# Default LiveView URL
bambu.printers.PRINTER_ID.stream.url=${bambu.live-view-url}${PRINTER_ID}

# Custom LiveView URL
bambu.printers.PRINTER_ID.stream.url=https://my_stream_domain.com/mystream
#

Bouncy Castle

X1C needs SSL Session Reuse so that SD Card functionality can work. Reference: https://stackoverflow.com/a/77587106/23289205

Without this you will see 552 SSL connection failed: session resuse required.

Add to .env:

bambu.use-bouncy-castle=true

Add JVM startup flag:

bash / cmd:

java -Djdk.tls.useExtendedMasterSecret=false -jar bambu-web-x.x.x-runner.jar

powershell:

java "-Djdk.tls.useExtendedMasterSecret=false" -jar bambu-web-x.x.x-runner.jar

Uploading bigger files

Add to .env:

quarkus.http.limits.max-body-size=30M

Configure XY/Z movement speeds

Add to .env:

# values are in mm/minute
bambu.move-xy=5000
bambu.move-z=3000

Use Right click for menus

Add to .env:

bambu.menu-left-click=false

Custom CSS

If you want to modify the CSS, create a file next to the .jar file called styles.css

Changing the display columns

Display columns is a ratio and scale based on screen width

Refer to bambu.css

Example	value for XXX
always 1 column	1
2 columns with 1080p	3
4 columns with 1080p	5

:root {
  --bambu-default-columns: XXX;
}

Debug

For debugging the application, add the following to .env and uncomment DEBUG or TRACE logging sections

### Log To File
quarkus.log.file.enable=true
quarkus.log.file.path=application.log


### DEBUG logging
#quarkus.log.category."com.tfyre".level=DEBUG


### TRACE logging
#quarkus.log.min-level=TRACE
#quarkus.log.category."com.tfyre".min-level=TRACE
#quarkus.log.category."com.tfyre".level=TRACE
