A1/A1 Mini Timelapse Mod

📸 Easy Timelapse Mod for Bambu Lab A1 & A1 Mini

Hello everyone!
I created a simple mod for the Bambu Lab A1 and A1 Mini that lets you easily make timelapse videos using your phone.

Timelapse videos are a great way to showcase your 3D prints in a fast, engaging, and satisfying format.
They perform extremely well on platforms like TikTok, Instagram, and YouTube Shorts, where short-form content grabs attention quickly.
The printing process becomes visually captivating in just a few seconds, increasing your chances of going viral or reaching a wider audience.

🧰 What You Need

Bluetooth remote shutter (1$): Aliexpress, Amazon.com
Your Android/Ios smartphone
A Free editor app: such as DaVinci Resolve (Desktop) or Velocity Lapse (Mobile);

🛠️ Installation

To install the mount:

Unscrew the front screw and bottom screw on the left side of the X-axis of your printer.
Attach the holder in place using those same screws.
Change the gcode on your print profile (see next step)

⚠️ Important

If the button does not press correctly in your case, you can modify the pin length from makerworld:

🧾 Timelapse G-code Setup

To make this work, you'll need to slightly modify the timelapse G-code section in your print profile.
IMPORTANT: if your print quality drop, please enable smooth timelapse, this will enable a purge tower.

Replace:

M400 P300

With:

M400 P10
G1 X10
M400 P300

🔍 This sequence does the following:

M400 P10: short 0.1s pause at the current position (X = 0)
G1 X10: moves the printhead away from the camera view
M400 P300: 3-second pause so your phone has time to take a picture

💡 If the printhead is still visible in your frame, feel free to adjust the G1 X... value.

Step 1:

Open Printer Settings

Step 2:

Under the ‘Machine gcode’ tab , scroll down until you find the Time lapse G-code, if you dont have the ‘Machine gcode’ tab please enable Advanced options

Step 3:

Locate the line ‘M400 P300’ after the external shutter comment and replace the G-code

Bonus Step (Thanks @user_1855328232):

I strongly recommend moving the printing bed forward before taking the photo. This will give the time-lapse better lighting, without any shadows. To do this, replace the following line:

G1 X0 Y{first_layer_center_no_wipe_tower[1]} F18000 ; move to safe pos

With:

G1 X0 Y250 F18000 ; move to safe pos

Step 4:

Save your profile
