bambu-farm

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/

1. 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.

2. FTPS Connections needs SSL Session Reuse via Bouncy Castle

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

3. Getting the LiveView to work requires additional software. For more details check the docker/bambu-liveview README.
4. 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.

I just want to run it

• Make sure you have Java 21 installed, verify with java -version

[user@build:~]# java -version
openjdk version "21.0.1" 2023-10-17 LTS
OpenJDK Runtime Environment Zulu21.30+15-CA (build 21.0.1+12-LTS)

Batch Print Section

Default batch printing options is below:

bambu.batch-print.skip-same-size=true
bambu.batch-print.timelapse=true
bambu.batch-print.bed-levelling=true
bambu.batch-print.flow-calibration=true
bambu.batch-print.vibration-calibration=true
bambu.batch-print.enforce-filament-mapping=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.

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

Display Filament Type instead of Name

Add to .env:

bambu.dashboard.filament-full-name=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;
}

Ordering items inside printer box

• Move display order of image / status / filaments “down” so that progress is after name

.dashboard-printer .image {
    order: 3;
}
.dashboard-printer .status {
    order: 4;
}
.dashboard-printer .filaments {
    order: 1;
}

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
