PicoBETH v2.91 Release Notes

Differences from v2.90

This version includes all improvements and test results from the v2.90A and v2.90B BETA versions. It delivers major enhancements to motor responsiveness, interface flexibility, and real-time tensioning accuracy.

1. Constant-Pull System Optimization

  • Significantly improved response speed of the constant-pull system.
  • Now stabilizes to the target tension in under 1 second, on par with ZeroBETH.

2. Tensioning Start Behavior

  • Tensioning now begins with near-zero delay, greatly improving overall smoothness.

3. Pre-stretch Setting Optimization

  • Pre-stretch values under 5% now adjust in 1% increments.
  • Available values: 0% / 1% / 2% / 3% / 4% / 5% / 10% / 15% / 20% / 25% / 30%.

4. Tension Indicator Light Logic

  • The yellow LED now lights up only when the target tension is reached, offering clearer feedback.

5. Faster Stepper Motor Operation

  • Increased motor speed and improved motion control for faster, smoother tensioning.

6. Internal Tension Logging Disabled

  • Disabled the previously unused tension log recording function to reduce memory usage.

Important Notes

  • This version requires manual upload of the updated LCD library: pico_i2c_lcd2.py to the src folder.
    → OTA update alone is not sufficient.

  • If issues occur after upgrading, revert to the previous firmware and report them in the
    GitHub Discussions.
