Bambu CLI

Overview

Use bambu-cli to configure, monitor, and control BambuLab printers over MQTT/FTPS/camera, producing exact commands and safe defaults.

Defaults and safety

Confirm the target printer (profile or IP/serial) and resolve precedence: flags > env > project config > user config.
Avoid access codes in flags; use
```
--access-code-file
```
or
```
--access-code-stdin
```
only.
Require confirmation for destructive actions (stop print, delete files, gcode send, calibrate, reboot); use
```
--force
```
/
```
--confirm
```
only when the user explicitly agrees.
Offer
```
--dry-run
```
when supported to preview actions.
Choose output format: human by default,
```
--json
```
for structured output,
```
--plain
```
for key=value output.

Quick start

Configure a profile:

bambu-cli config set --printer <name> --ip <ip> --serial <serial> --access-code-file <path> --default

Status:
```
bambu-cli status
```
Watch:
```
bambu-cli watch --interval 5
```

Start print:

bambu-cli print start <file.3mf|file.gcode> --plate 1

Pause/resume/stop:
```
bambu-cli print pause|resume|stop
```

Camera snapshot:

bambu-cli camera snapshot --out snapshot.jpg

Task guidance

Setup & config

Use
```
config set/list/get/remove
```
to manage profiles.

Use env vars to avoid flags in scripts:

BAMBU_PROFILE

BAMBU_IP

BAMBU_SERIAL

BAMBU_ACCESS_CODE_FILE

BAMBU_TIMEOUT

BAMBU_NO_CAMERA

BAMBU_MQTT_PORT

BAMBU_FTP_PORT

BAMBU_CAMERA_PORT

Note config locations: user

~/.config/bambu/config.json

, project

./.bambu.json

Monitoring

Use
```
status
```
for a one-off snapshot; use
```
watch
```
for periodic updates (
```
--interval
```
,
```
--refresh
```
).
Use
```
--json
```
/
```
--plain
```
for scripting.

Printing

Use
```
print start <file>
```
with
```
.3mf
```
or
```
.gcode
```
.
Use
```
--plate <n|path>
```
to select a plate number or gcode path inside a 3mf.
Use
```
--no-upload
```
only when the file already exists on the printer; do not use it with
```
.gcode
```
input.

Control AMS:

--no-ams

--ams-mapping "0,1"

--skip-objects "1,3"

Disable flow calibration with
```
--flow-calibration=false
```
if requested.

Files and camera

Use

files list [--dir <path>]

files upload <local> [--as <remote>]

Use
```
files download <remote> --out <path|->
```
; use
```
--force
```
to allow writing binary data to a TTY.
Use
```
files delete <remote>
```
only with confirmation.
Use
```
camera snapshot --out <path|->
```
; use
```
--force
```
to allow stdout to a TTY.

Motion, temps, fans, light

Use
```
home
```
,
```
move z --height <0-256>
```
.
Use
```
temps get|set
```
(
```
--bed
```
,
```
--nozzle
```
,
```
--chamber
```
; require at least one).
Use
```
fans set
```
with
```
--part/--aux/--chamber
```
values
```
0-255
```
or
```
0-1
```
.
Use
```
light on|off|status
```
.

Gcode and calibration

Use

gcode send <line...>

gcode send --stdin

(confirmation required;

--no-check

skips validation).

Avoid combining
```
--access-code-stdin
```
with
```
gcode send --stdin
```
; use an access code file instead.

Use

calibrate

with

--no-bed-level

--no-motor-noise

--no-vibration

when requested.

Troubleshooting

Use
```
doctor
```
to check TCP connectivity to MQTT/FTPS/camera ports; suggest
```
--no-camera
```
if the camera port is unreachable.
Assume default ports: MQTT 8883, FTPS 990, camera 6000 unless configured.
