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.

Please note this is the first release so use with caution and run lots of tests. Any problems contact me via the comments or the website Happy foam cutting
