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 1 shows how it works and Part 2 will cover compiling the firmware, install, configuration and calibration test.
A full post on my website covering the above. https://rckeith.co.uk/4-axis-cnc-foam-cutter-using-marlin-3d-printer-firmware/
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
