A1 mini Firmware 01.01.01.00(2023.11.02)

Overview

[New Features]

  1. Added support for printer model verification of 3mf files when printing from SD cards.
  2. Added Y-axis guide rails maintenance reminder.

[Improvements]

  1. Optimized tool head flushing filament position
  2. Updated the filament list

[Bugs fixed]

  1. Fixed some incorrect copywriting
  2. Fixed the problem where when printing is paused due to AMS abnormality, it cannot be resumed after replacing the hot end.
  3. Fixed the problem where printing was initiated in Bambu Handy’s print history and selected to skip some parts, but the skipping does not take effect.
  4. Fixed the issue where the printing process stopped abnormally but prompted printing is complete.

Added support for printer model verification of 3mf files when printing from SD cards.

Bambu Studio version needs to be 1.8.0 or higher.

Due to structural differences between the A1 mini and other Bambu Lab 3D printers, slicing files configured for the X1 or P1 will cause errors when printed on A1 mini. In this version, we have added printer model checking for 3mf files.


Printer Configuration Selection

Rule:

  1. If A1 mini is selected when slicing, there will be no prompt when initiating printing.
  2. If X1, X1 Carbon, X1E, P1S, or P1P are selected when slicing, a compatibility prompt will appear when initiating printing, and printing will not be allowed.
  3. Gcode files will not be verified.

A1 mini Firmware 01.01.00.00 (2023.10.19)

Overview

[New Features]

  1. Added support for model objects being skipped from Bambu Handy; SD card and LAN printing are not yet supported.
  2. Added heating protection when the hot end is not installed.
  3. Added support for preheating the heat bed when downloading sliced files.
  4. Added a maintenance mode that allows users to heat the hot end heating assembly without having the hot end installed.
  5. Added a pop-up prompt when controlling the extruder with the nozzle temperature below 170°C.
  6. Added support for modifying color presets over for colors when printing via SD card.
  7. Added display of 3mf error prompts for SD card printing.

[Improvements]

  1. Optimized extruder motor noise.
  2. Optimized filament tangle monitoring trigger threshold; added display of the wiki QR code when filament tangle monitoring is turned on.
  3. Optimized automatic color mapping function in SD card printing.
  4. Optimized time-lapse in traditional mode.
  5. Changed report status to “Canceled” when canceling prints.
  6. Updated the list of supported filaments for the printer.
  7. When the hot end temperature is abnormal, the current temperature of the hot end will be displayed normally to prevent burns from the actual high temperature nozzle unless the hot end temperature sensor circuit is shorted or disconnected.

[Bugs fixed]

  1. Fixed the problem of incorrect 3mf color preset display when initiating a print from the screen
  2. Corrected some translation errors in the text
  3. Fixed the problem of some files with special characters not being displayed in the file interface

[Remaining issues]

  1. When printing with an SD card and the temperature of the heat bed for slicing is higher than the softening temperature of the filament, an error prompt will appear to open the front door, which should be “keep in a ventilated environment”
  2. When initiating a print, if the FTP channel is used to transfer the print file, the preheating function will not work.

Added heating protection when the nozzle is not installed and maintenance mode.

The hotend of the A1 mini includes the hotend heating assembly and the quick swap nozzles. When a quick swap nozzle is not installed, the hotend heating assembly could still work independently and maintain high temperatures, which could potentially cause burns.

The hot end protective function is triggered and automatically turns off the hotend heating assembly when it detects that the hotend heating assembly is in a heating state and the hotend is not installed. At the same time, an error pops up on the “Assistant” page of the printer screen. This protection can be cleared in the following 3 ways after the hotend is reinstalled:

  • Reboot the printer
  • Start a new print task
  • Click the “Resume” button during printing
  • On the “Settings->Maintenance” page, turn on and then turn off maintenance mode.

The hotend of the A1 mini needs to be regularly cleaned to remove substances stuck on the surface of the hotend heating assembly for optimal performance. Some of the substances need to be cleaned after appropriately increasing the temperature of the hotend heating assembly. Users can temporarily turn off the uncovered protective function of the hot end after disassembling it, by turning on the hot end maintenance mode in the “Settings -> Maintenance” page. The hotend heating assembly can be heated independently after turning off. Please refer to the hot end cleaning instructions. A1 mini Maintenance Guidelines: A1 mini Maintenance Guidelines

Traditional Time-lapse

Because the hot bed will continuously move back and forth during the printing process, when the printer is shooting time-lapse photography, it will suffer from image timing issues, and the time-lapse will appear distorted.

In version 1.7.7.89, Bambu Studio calculates the center of the model in the Y direction for the first layer. Then, the inner and outer walls of models are printed before the printer moves to align the camera to the center of the model while the toolhead moves to the purge wiper. After the photo is taken, each layer continues to print.

Notes:

  1. During this process, a small amount of filament leakage may occur when the tool head moves. The majority of this leakage will be removed by the extrusion assembly, while a small portion will be used as infill inside the model, minimizing the impact on model quality due to print pauses.
  2. Since this process requires writing into the sliced file during slicing, the estimated model printing time may increase.
  3. Time-lapse is not supported when printing by object or in vase mode.
  4. Enabling time-lapse photography in traditional mode and using the part-skipping feature may affect the printing outcome.

A1 mini Firmware 01.00.00.00

Overview

[New Features]

  1. Added non-LAN binding.
  2. Added dynamic flow calibration.
  3. Added motor noise cancellation calibration.
  4. Added filament tangle monitoring.
  5. Added nozzle filament wrapped detection.

Added support for filament tangle monitoring

Filament entanglement, usually refers to the entanglement of the filament on the spool, resulting in the extruder unable to pull the the filament during the printing process and thus stop the extrusion. And usually in this case, the filament detection sensor of the tool head is still be triggered, it cannot trigger the filament-run-out reminder, which will cause the phenomenon of “air printing” during the printing. The Bambu A1 mini is equipped with a filament tangle monitoring module to deal with this situation. When the filament is tangled, due to excessive feeding resistance, the corresponding sensor will be triggered, and the printer will automatically pause printing and pop up a reminder of filament entanglement. Customers can re-arrange the filament on the spool and continue printing. Avoid “air printing”.

  1. Function Usage Restrictions
  • The filament tangle detection function is supported by both external filament tray printing and AMS lite printing.
  • The filament tangle detection function is not applicable to all types of consumables. Also, incorrect installation of the filament tube or tray will affect this function. For more information and usage precautions about filament tangle detection function, please refer to https://wiki.bambulab.com/zh/ams-lite/manual/filament-tangle-monitoring-intro

Added support for nozzle filament wrapped detection.

Nozzle filament wrapped, usually because the filament does not stick to the build plate, wraps the nozzle, causing printing failure or even damaging the extruder. Because of the possibility of damaging the device, Bambu A1 mini is equipped with a nozzle filament wrapped detection module to deal with this situation.

The extrusion force sensor is used to detect whether the nozzle is wrapped by filament, if the nozzle is wrapped by filament, or if the build plate is placed incorrectly, the force on the nozzle will change. When the nozzle filament-covered-detection is turned on, the nozzle will move outside the heat bed after the printer finishes printing the outer wall of the third layer, and then continue to move down. If the nozzle is wrapped by the filament, forming a thick material mass, the process of the above movement will cause the material mass to hit the heat bed and cause the force change. The change in force will be detected by the extrusion.

When the nozzle filament wrapped is detected, the printer will automatically pause printing and pop up a nozzle filament wrapped reminder. The user can judge whether it is a false alarm or a problem. If there is a problem, please perform processing corresponding to the nozzle filament wrapped detection, clean the wrapping nozzle or relocate the build plate.
