| Software notes | Native Klipper firmware with Moonraker API. Recommended web interfaces: Mainsail or Fluidd. Compatible with standard slicers: UltiMaker Cura, PrusaSlicer, OrcaSlicer, IdeaMaker, Simplify3D. No proprietary software required. Unlimited root access: the user can modify configurations without restrictions. | The A1 works natively with Bambu Studio, Bambu Lab's proprietary slicer available for Windows and macOS, which handles slicing, automatic calibrations, and remote monitoring via the Bambu Handy app. Third-party slicers — including PrusaSlicer, SuperSlicer, and Ultimaker Cura — are supported via standard G-code export, but advanced features such as vibration compensation and active flow control are only available within the Bambu ecosystem. |
The differences that matter
- Price about 334 € vs 429 € → the M1 Pro S1 costs about 95 € less.
- Native Klipper with root access only on the M1 Pro S1 → configuration can be changed without restrictions.
- Bambu Studio and the Handy app only on the A1 → automatic calibration and remote monitoring ready out of the box.
- Multicolor up to 4 colors with an accessory on the A1 → the M1 Pro S1 doesn't state it.
Which one to choose
Choose M1 Pro S1 if…
M1 Pro S1: native Klipper with Moonraker, a Mainsail or Fluidd web interface, unrestricted root access and your choice of slicer among Cura, PrusaSlicer, OrcaSlicer, IdeaMaker and Simplify3D. It is for anyone who wants to change how the machine is configured. The trade-off: calibration and monitoring are yours to manage, without Bambu Studio's guided flow.
Choose A1 if…
A1: Bambu Studio runs the automatic calibrations and remote monitoring goes through the Bambu Handy app; multicolor reaches 4 colors with an accessory. The trade-off: about 95 € more, an open frame with no enclosure, and features such as vibration compensation and active flow control available only inside the Bambu ecosystem.
