CNC hot wire foam cutter using Marlin 3d printer firmware Part 2

The 4-axis CNC foam cutter until now required a Windows computer to run the software to send g-codes to the controller. Several times I have been asked if there is a way to run the foam cutter like a 3d printer by just inserting an SD card with the g-code. In this video, Part 2 covers hardware and software for compiling the firmware, installation, configuration, calibration, homing, hot wire settings and cutting a test aerofoil.
