X1Plus version 3.1, supporting Bambu Lab X1 and X1 Carbon printers.

To update to X1Plus 3.1 from version 2.0 or higher, use the built-in over-the-air update mechanism. From earlier versions, please follow the "manual upgrade" steps in the user manual.

In this release:

• Added experimental support for connecting to Polar Cloud; you can now remotely manage and print to an X1-family printer without using the Bambu Cloud! This feature is disabled by default. For more information on Polar Cloud, visit https://polar3d.com/. Thanks to Polar3D, Inc. for sponsoring the development of this feature!
• Added support for updating firmware on all four AMSes.
• Added support for displaying data in the GUI from sensors connected to X1Plus Expander.
• Fixed X1Plus firmware bug with selecting TPU for AMS on device (not to be confused with the Bambu firmware bug that I fixed in the previous release and then created this bug, oopsies).
• Updated to Bambu filament database 02.01.00.25.
• Fixed a bug where the printer could not download a 3MF from the cloud without WiFi being connected (even if Ethernet was also connected).

Known issues:

• Actions from Gcode may infrequently fail to trigger, especially if the printer is under heavy load.
• The Bambu camera service has a resource leak across connect/disconnect cycles; this issue comes from the base firmware, but can be exacerbated when Polar Cloud is active. If the camera becomes unresponsive, restart the printer.
• AMS 2 Pro and AMS HT are not yet supported in X1Plus.

Offline install files

To install this version of X1Plus onto your printer without a network connection, you will need to download the following files:

• Place the 3.1.x1p from this release into the root (/) of your SD card.
• Place the MC firmware, mc_rev7-firmware-v00.00.27.26-20240422094119_product.bin.sig, at /x1plus/firmware/mc_rev7-firmware-v00.00.27.26-20240422094119_product.bin.sig on your SD card. It should have md5sum 44b644103fde8f38f1e4db28c0fd61e0.
• Place the AMS firmware, ams_rev8-firmware-v00.01.06.62-20250331204240_product.bin.sig, at /x1plus/firmware/ams_rev8-firmware-v00.01.06.62-20250331204240_product.bin.sig on your SD card. It should have md5sum 61d0b28d20f1de27d341323116210f1f.
• Place the AP firmware, update-v00.00.32.39-20240805174856_product.img.zip.sig, at /x1plus/firmware/update-v00.00.32.39-20240805174856_product.img.zip.sig on your SD card. It should have md5sum 1e1003789a9ea7326c206aa99c174632.
• Place the filament database, ota-filament-v02.00.00.89-20250506161431.zip.sig, at /x1plus/firmware/ota-filament-v02.00.00.89-20250506161431.zip.sig on your SD card. It should have md5sum d04c4d74f71a77b4d383d1abb085f299.

Please note that if you are copying files to your SD card over FTP while it is inserted into your printer, it can take a few minutes for the file to finish being written to the SD card, even when your FTP client says that the transfer is complete. Restarting your printer before this completes will result in the file being corrupted on your SD card, which could cause installation to fail. To avoid this, when using FTP, wait three or four minutes before restarting your printer to ensure that the files have been fully written.
