A simple python script to send gcode file using serial to various machines.
This is a simple python script to send gcode file using serial to various machines, such as 3D printer, laser engraving machine, CNC machine and etc. The script has currently been tested on Windows 10 to send a gcode file to a DIY 3D printer (MKS TinyBee motherboard and Marlin firmware). The gcode file was generated using UtiMaker Cura.
Features
- Automatically detects available serial port
- Update sending status dynamically
- Programmatically sends gcode over a USB port
- Easy to use, only needs pyserial and tqdm installed python3 environment

Congratulation!!!
Welcome to use this simple script again. Best wishes.
====================================================================================================- Caution: When you use this script for the first time in a new environment, please always monitor the running status of your machine to avoid unexpected situations.
- When the script is running, single click on the terminal console will suspend the sending process. Press "Enter" key to continue.
- Baud rate of host computer and microcontroller must be same. If baud rates are different, no error will be thrown. However, the machine will not work and the program stay stuck. The next situation is an instance.

Just wait until the temperature increased to specified value patiently.
