v2.72

PicoBETH v2.72 Release Notes

Various fixes and improvements

1. Added Boot Mode Selector

• By pressing and holding specific keys, then powering on, you can now enter different modes:
  • Up Key: Enters Reliability Testing mode
  • Down Key: Enters Software Update mode
  • Middle Key: Enters Hardware Function Testing mode
  • Right Key: Displays system logs (sys_log.txt)
  • Exit Key: Performs a Factory Reset

Note: Do not release the keys until you see the mode displayed on the LCD screen.

2. Enhanced System Log Recording

• Improved error handling by using try-except to capture exceptions and log the details into sys_log.txt for more effective debugging.

3. Improved Constant Pull Mechanism

• Enhanced the smoothness of tension control during the constant pull process, providing a better user experience.

Important Notes:

We highly recommend following the software update instructions carefully, which can be found at Firmware Update Instructions.

In the fast mode after version 2.70, when the speed is set to L7 or higher and the tension exceeds 30LB, the original 12V3A power supply may be insufficient, potentially causing the motor to slip. Therefore, this version has been upgraded to a 19V4A power supply. If you also plan to switch to a 19V power supply, please ensure that your 5V power converter can handle a 19V input voltage. Additionally, if you are using an external UPS, it should also be upgraded to a version that can accept 19V input and output.

If you encounter any issues during the upgrade, please revert to the previous version and report the issue in the GitHub discussions. We also invite you to share photos of your completed projects and join the conversation in the GitHub discussions!
