- Fix the problem of incorrect extrusion acceleration and printing acceleration in the configuration file.
- Fix the temperature measurement problem of PT100 between 200℃~210℃.
- Optimize parameter input. When inputting parameters, it is no longer necessary to delete the original parameters first, and users can directly input new parameters.
- Optimize the timing of the motor direction drive signal and pulse signal to ensure that the motor drive timing meets most external drives (the establishment of the direction signal takes priority over the pulse signal 10us).
- Add the function of automatically saving the LED parameters, so that the brightness of the LED and the color of the RGB LED will be the values at the time of the last shutdown when the device is turned on next time.
- Increased the stability of wifi file transfer.
