Unable to install plasmac configurator.py file not found

Hello everyone I am asking for help and insights with installing plasmac to a base machine configuration of a cnc plasma table. I tried installing plasmac using the terminal and following instructions however when I enter the command to start the configurator it says "python: command not found". so I use the alias command to point python to python3 and then I get this second error "no such file or directory". I then checked where my path was pointing to in file explorer and there is no plasmac folder in the by_machine folder and also searching the whole system shows no configurator.py file. I just want to install plasmac any help or insights are greatly appreciated!
