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.
- Not for production farms. Run beta builds on a test printer or a single FarmLoop unit you can babysit, not on the whole farm.
- Things may regress. Trigger reliability, OTA behaviour, MQTT routing - anything we changed is fair game for unintended side effects.
- Please report what you see. If a beta misbehaves, send us the OTA log +
.gcode.3mfunder the Technical issue category. Mention the beta version in the subject line. - You can always roll back. Each beta lists the stable build it diverged from - re-flashing that file from the main Firmware page returns you to a known-good state.
Current betas
Section titled “Current betas”There are no beta builds right now.
The previous beta wave shipped as official releases in July 2026 - P/X
v2.94, A series v1.50, and H series v3.1 are all available on the
main Firmware page. If you were running one of the final beta
revisions (2.94-beta-rev4, 1.50-beta-rev3, 3.1-beta-rev3), the stable
build is identical - updating is optional but keeps your version string clean.
Flashing a beta
Section titled “Flashing a beta”The flashing procedure is identical to a stable release - pick the route that fits your setup:
- USB-C flash from your browser - recommended when you have a USB-C cable handy.
- OTA upload from the board’s web page - no cable needed; works from any phone or laptop.
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:
- The FarmBoard log - the Download .txt button on the board’s web page (see Getting logs from the FarmBoard).
- The
.gcode.3mfof any print that triggered the issue. - A one-line description of what you expected vs. what happened.
We read every report and reply within one business day.
