Beta firmware

Beta builds are pre-release firmware we publish here so the community can help validate fixes and new features before they’re promoted to the stable Firmware page.

Current betas

Section titled “Current betas”

This wave adds web access to the FarmBoard over your normal WiFi, including firmware updates directly from the board page. The latest revision also keeps far more history in the board’s log, which makes support cases much easier to trace. Roll back targets: P/X v2.94, A series v1.50, H series v3.10 on the main Firmware page.

P/X Series - 2.95 beta (rev 13)

Bambu P1P, P1S, P2S, X1C, X2D

Release notes

  • Set your printer model first. After updating, open the board page (on rev 12 that means config mode: tap SW2 five times and join the FarmLoop WiFi) and choose your printer in the Printer Model box at the top, then press Save. Do this before your first print. It sets the direction the bender arm travels, which is not the same on every kit, so leaving it wrong will drive the bender the wrong way.
  • Rev 13: the LED now shows the connection. Off means Mechanical mode. One blink per second means Digital mode is connected to your printer. Two quick flashes then a pause means Digital mode is on but nothing is arriving from the printer. This works without opening any page, which matters while the board page over WiFi is switched off.
  • Rev 13: Reboot now to connect. After saving printer details in config mode, a reboot button appears. The board runs its own WiFi network while you are on that page, so it cannot reach the printer until it restarts.
  • Rev 12: board page over your WiFi is switched off. This is deliberate and temporary, to test whether it is what disturbs the connection to Bambu printers. Reach the settings page with config mode instead: tap SW2 five times and join the FarmLoop WiFi network.
  • Rev 11: shorter address for the board page (rev 11 and earlier only). The board answers to http://farmloop.local when it is the only FarmBoard on your network, so there is no board code to look up. With several boards, the page lists them all so you can pick.
  • Rev 10: much easier setup. The setup page now opens by itself when you join the FarmLoop WiFi, lists nearby WiFi networks instead of typing, and tests the WiFi and printer connection with clear results before you save.
  • Rev 10: update from the board page. A Check for updates button downloads and installs the newest stable firmware for you, with confirmation. No more file downloads.
  • Rev 10: built-in diagnostics. A self-check panel spots the common problems (weak WiFi, printer connection, switch not registering) and a single Download diagnostics file gives support everything needed in one attachment.
  • Web access over your WiFi (rev 11 and earlier only, switched off in rev 12): open the FarmBoard page at http://<board IP> or http://farmloop-XXXXXX.local without config mode.
  • Firmware update in the browser: upload new firmware directly from the page. Works only while the unit is idle and the printer is not printing.
  • Better support logs: the board now keeps a record of many ejection cycles instead of only the last one, so a problem can still be traced after it happened.
  • More reliable on unstable printer connections: if the connection drops and comes back, the limit switch stays active for two minutes, so a missed trigger still fires mechanically.
  • Live status and log: check the connection, watch the live log and download it for support tickets.

FarmBoard 3 needs to be powered via the AMS plug before USB-C flashing - the USB-C port alone doesn’t power the chip.

Flashing a beta

Section titled “Flashing a beta”

The flashing procedure is identical to a stable release - pick the route that fits your setup:

Rolling back

Section titled “Rolling back”

If a beta misbehaves, re-flash the matching stable build from the main Firmware page. Both USB-C and OTA support the round-trip - there’s no special “downgrade” mode.

Reporting issues

Section titled “Reporting issues”

Bug reports are what make betas useful. Please open a Technical issue ticket and attach:

  1. The FarmBoard log - the Download .txt button on the board’s web page (see Getting logs from the FarmBoard).
  2. The .gcode.3mf of any print that triggered the issue.
  3. A one-line description of what you expected vs. what happened.

We read every report and reply within one business day.
