Pywing is a all-in-one software for hot wire foam CNC cutting. It can generate G-Code for other softwares or directly communicate with a 4-axis(XYUV) Grbl through serial link (see https://github.com/proto3/grbl/tree/hotwire).
It has no drop down menus, so everything you need is visible. Just try scrolling on each field and you will see instantly what it does in the 3D view.
First of all, clone the repository and open a terminal inside pywing folder.

# create a python3 virtualenv inside pywing folder
virtualenv -p python3 env
# activate your virtualenv
source env/bin/activate
